Let me just tell you like how that device was actually made here. We go Music, Music, so yeah thats how that device was actually made, and now in this video ill. Let you know everything about this device like what i specification. What kind of sensors comes built in this particular device uh? What is in its built in firmware how its built in firmware actually works that ill, let you know and in the end ill also let you know how to program this board using arduino ide for fetching all the census, data and printing them on the serial monitor. So this is the only video to watch for your all the smart, uh gardening based projects and without wasting time lets start with this video. Now talking about the specifications of this board, then this board is based on the esp32 chip, so we can expect the built in wi, fi and bluetooth connectivity option, along with the 4mb of flash memory built in now. What makes this board different from the other boards are the built in sensors, so this board has built in capacitive, soil, moisture sensor, an ec sensor or electrical conductivity sensor, which can sense the amount of source in the soil, dht11 sensor for measuring temperature and humidity bh1750. For light intensity monitoring and a dedicated i2c port for connecting external i2c based sensor now, along with that, there are a couple of more features which makes using this board more convenient, which is it has battery connector port, along with the battery charging circuit on board.

It also has a type c connector for both powering up the board and charging the battery, and in case we need to add more sensors or relays or any input output devices. We do have couple of gpio pins exposed on the boards so that we can easily attach the input, output, devices and last, but not the least. This board also had a dedicated reset button on the board, so that was all about the hardware specification of the board. Now lets try to power up the board and lets see what we are getting in the built in firmware so now ill. Let you know what comes in the built in firmware of this ttgo high growth. So right now i powered on this device and all the devices like when you get this new product uh it already uh, be having its built in firmware. You just need to power it up. It will start working okay, so what it will do it will be acting as a hotspot, okay or access point which you can connect it on your smartphone. So i directly connect it to the statigo board, so ill go to my wi fi section and uh. Here, probably a new network should appear lets just wait for it. Okay, so here it is t high growth, so ill connect to it directly. It is an open network. It got successfully connected now ill go to my web browser and type the ip address as 192.

168.4.1. Now this will be the static ip address, so the ipaddress will be same for all the users. Okay. So when i open that link, it should show me one web page lets just wait for a couple of seconds. Okay, so page is loaded right now and, as you can see, we are able to see the data of different different sensors. The first is the light sensor. Second, is the soil moisture sensor? Third, is the salt value salt percentage, then the battery value? Then the bme sensor, which is not at all connected, so the value, is zero. Zero and dht temperature is 27 degrees celsius. Then dst unit is 35 percentage. Okay, so all the census data we are getting straight away in the built in firmware so ill insert the sensor in the port and lets observe the real life data, real life values of all these sensors, so ill, dig it inside this soil, uh, okay and lets See the values okay, so right now the value is uh like the light value is almost same because the light condition havent changed, but soil value changed to 50 percent. So the moisture level of the soil is decent enough. 50 is good. Salt value is also good enough, which is 163 percent. Now, in the latter video like later in this video ill, let you know uh how the salt number reveals that whether this plant needs some soil or sorry need some salt or not so ill.

Let you know while well be programming this particular port. Okay, then the battery voltage will be the same and the temperature inverted will be the same. Lets try to add some water and lets see what happens with the you know: soil, moisture values, okay, so ill. Pour some water in the pot and, as you can see, the value increased to 63 percentage 62 percentage. I added a little bit of water to it. Uh just to test everything is working or not. Okay, so everything seems pretty defined like pretty working fine. So whenever you get the sensor, its a standalone device, its ready to be used, so you can plug it in and youll be working flawlessly without you know programming any damn thing inside this board. But still, if you want to program, we do have the option for that as well. We can definitely program it using arduino ide. So now let me take you to my arduino ide and let me show you how to program the board to get all the sensors data individually so that we can use it for our next projects. So heres my arduino ide screen and here is the demo code, which i made to fetch the sensors data, like all the sensors data individually, and it will require a couple of library to be installed. But before that, you need to have the esp32 boards package already installed onto your arduino ide, so make sure you do that step if you dont know how to do that ill.

Leave the link for that video down in the description so that watch it out and install the esp32 board after installing the board. You also need to install the dht11 sensors library uh, the bh1750, the light sensor library. Then you need to download yeah thats, pretty much it uh. Other sensor will be based on the i2c protocol, so wire dot. H will be enough for that particular thing. Great pretty common. After that we have defined the pins for all the uh, sensors and yeah. All these sensors and the buttons you can say the boot button and also the power control now the power control is a really important thing. If you program the board program, this particular tt group board by just you know, reading the sensors data it wont work with all the sensors. Yes, i tried that out. If you simply upload the code of reading sentences data, it wont work its just because of this power control. Pin is the power control, pin is kind of an architecture, kind of a design that ttco made its a brilliant design for sure. But if you dont know its design, if you dont know this single pin, you wont be able to use the sensors data. You wont be able to fetch the sensor. Even the sensor wont get powered up okay. So what you could do is to use the sensor. You need to power this power control, pin as one or rather you need to provide a digital high signal to this pin and then youll be able to read the census data thats thats, the catch.

You can say, okay, you. Let me know why this ttgo team had did this particular thing into that architecture. Do you know the reason i know my team know, but what about you do you know that do do? Let me know if you know the reason down in the comments, if you dont know. Well, i let you know the reasons, maybe in instagram sorry to follow me on instagram as well great okay. Those lines of code were not really important for this video. It is about my upcoming project so ill. Let you know about that project in the end of the video stay tuned. So here you just need to mention the minimum maximum soil moisture value. Now how you can get this value? Well, you just need to use this sensor and you need to you know dip this sensor inside a bowl of water and that will give you the maximum value and just remove the sensor. Just drop this uh capacitive soil, moisture sensor and whatever the value you get. Will be the soil minimum value, so you need to diff, you know, take out those values and mention those values here. In my case, it is one six, three, eight four maximum one, three, two, eight five for the minimum value ticket, uh and likewise youll – be able to map like whether the soil, moisture, zero percent or hundred percent great. After that, the uh initializing. This light sensor is liking, the dht one more sensor, pretty common and then yes, what we did is.

We are just printing the data of all the sensors. Now this was pretty common. The only catch here was the power, control, pin and thats. Why? I need to discuss you uh about this thing in this video. Everything is pretty common now. One thing is this: this particular thing is also a soil, a salt sensor, okay, so whether this flower pot do require some salt or not look how we will be able to judge that. Well, here i have provided some values, or rather i got the values from the official uh td go library or did you go get a page and they said that if the value is less than 201, that means it needs some sort. It needs some or what you can say organic compound. You can see okay if it is uh less than uh 251. It means its. It has some salt, but it is a low amount. Okay, 351 is the optimal. It is good good number and above 350, its too high okay. So, accordingly, you will be able to see whether this plant or your smart garden has enough amount of salt or not okay. So this will give you the salt advice and then temperature humidity and battery status pretty gone because yeah, all the things is pretty straightforward, using the library and thats it about this particular code, nothing much nothing major other than the power control pane. Now, what ill do is select the right board, which is especially the ruler, module, write, com, port and straight away, hit the upload button and after the code gets uploaded.

Let me show you how the data looks like in the serial monitor. In the meantime, you can do one thing, which is you can like this video. If youre really interested in this particular sensor, i want to try it out for your next project. Do click the like button. Also, let me know in the comments about what will you be making after you get this kind of sensor in your hand, and also, let me tell you, im planning to make a future video about the smart pot. 2.0. Okay. So if you dont know what the smart pot is, then here is the video of a smart pot, which is about expressing the feelings of the plant. Whether the plant is feeling thirsty, whether planting plant is feeling cold hot. Every expression is like displayed onto the display and im thinking to make a better version advanced version, a very uh like a different thing, like updated version of this plant, which will be smart, pod, 2.0 and im really excited to drop the video of it. And maybe you are excited too so ill soon drop the video of that and yeah. In the meantime, the code got already uploaded, so i open the serial, monitor and lets see the data here. As you can see, printing all the data of all the sensors ill pause this as of now so lux values, 786. So light is very very good here, because there is a ring light here.

There is a dome light here. Okay, then, the soil moisture says seven. This is something very strange: uh, seven percent. Okay, is it seven percent only. Let me just dig it deep inside the soil and let me check the values again. It should not be seven yeah, its 83 percent, so it has adequate amount of soil, moisture. Uh salt advice is needed; it needs some salt, so ill. Take care of this particular thing. Temperature is 27, humidity is 40 percent battery voltage is 5 because i powered up with the usb cable, so yeah. Of course, it should be showing as 5 volt only chicken. That said, that is all the data that we are getting here and like. If i turn off the light sensor, if turn off the lights here well, the value will decrease uh. Let me just turn off the light yeah. So now the light value is 0.83, so its totally 1.6 and so its totally dark here. So yeah everything is working pretty fine. Let me turn it on everything again and yeah. That was all about this ttgo high growth. Sensors and i covered pretty much everything about the sensor from the specification to the demo firmware to the demo code, which ill definitely provide you onto my github repository, which i think you can find in the description of this video and yeah thats it about this. Video. Do subscribe, my channel if you want to see that smart point 2.

0 video and also some other project, videos in the field of electronics, iot and automation and yeah. That being said, i am just ending this video here and now. Just wait for my next explorer.
