RS485 Soil Moisture & Temperature Sensor
The RS485 Soil Moisture & Temperature Sensor is a device designed to measure the moisture and temperature of soil. It operates at 5 volts and can be interfaced with any microcontroller using the RS485 communication protocol. The sensor has a built-in temperature sensor and a soil moisture sensor, with a range of 0 to 50C and 0 to 100% respectively. It also has a built-in EEPROM memory which stores the calibration values.
Max 485 Module
The Max 485 Module is used to convert the serial data to the RS485 protocol. This protocol is used to communicate with the sensor. It is connected to the data pin of the sensor and the ground pin of the Arduino.
OLED Display
The OLED Display is used to display the values of soil moisture and temperature. It is connected to the Arduino and the values are displayed on the display.
Testing the Sensor
To test the accuracy of the sensor, various tests are conducted. The values of soil moisture and temperature are measured and compared with the values obtained from other sensors. If the values match, then the sensor is deemed to be accurate.
Altium 365
Altium 365 is an electronics product design platform that unites specific design, MCAD, and management and teamwork with Altium 365. It provides a centralized cloud storage, a fast search engine, and allows teams to work together on a single product. It also helps with component management and can send designs to a manufacturing unit.
This display is used to display the measured value.
RS485 Soil Moisture & Temperature Sensor
The RS485 Soil Moisture & Temperature Sensor is designed to measure soil moisture, worms, and wetness. It is compared with a high-quality German sensor to ensure accuracy and reliability. This sensor is quick to give results and can be left in the ground for a long time without being covered or damaged due to its waterproof construction. The sensor works between a voltage range of 4.5 to 30 volts DC with a typical power consumption of 0.4 watts. The moisture measurement range is between 0 to 100 percent, while the temperature range is between 40 to 60 degrees Celsius. The probe material is made of 304 stainless steel with an IP68 production class.
Using the Sensor
The sensor can be used in two ways. The first method involves inserting the three needles in the soil vertically, making sure the needle does not hit any hard objects. The second method is for long-term usage, whereby the sensor is buried in the soil and the readings become stable. This method can be used for several days, months, or even longer to measure soil, humidity, and temperature values.
Components Needed
Using this sensor requires the following components: an Arduino Nanoboard, a Modbus RDU module, and a 0.96 inches I Square c o LED display. The Nanoboard is used since the sensor output is RS485, while the Modbus RDU module is used to easily interface the sensor with a microcontroller. The LED display is used to display the measured values.
Connecting the Components
To connect the components, the Arduino Nanoboard is connected to the Modbus RDU module. The Modbus RDU module is then connected to the RS485 Soil Moisture & Temperature Sensor. The LED display is connected to the Arduino Nanoboard. Once the components are connected, the Arduino Nanoboard can be used to read the values from the sensor and display them on the LED display.
Introduction to RS485 Soil Moisture & Temperature Sensor
The RS485 Soil Moisture & Temperature Sensor is a device used to measure the moisture and temperature of soil. It is equipped with a 4-wire interface, allowing it to be connected to an Arduino board or other microcontroller. The sensor is capable of measuring the moisture and temperature of the soil, and can be used to monitor the health of plants and crops.
Connection Diagram
In order to use the RS485 Soil Moisture & Temperature Sensor, a breadboard is required for prototyping and assembly. The connection diagram for this project is as follows: the Arduino Max 485 is connected to the soil sensors, and a 5 volt supply is connected to the Arduino Nano.
Reading Sensor Values
In order to read the sensor values, a sample code is developed. This code is used to read the sensor values from the manufacturer data set. The inquiry frame and response frame are explained in detail. Once the code is uploaded to the Arduino Nano board, the OLED display will show the room temperature values correctly. However, for soil moisture values, it may appear as 0. This is because the sensor may be exposed to dry air, causing the needles to move. When the sensor is touched with a finger, the conductivity will cause a change in the OLED display. After the finger is removed, the values will go back to 0.
Testing the Sensor
In order to test the sensor in the field, it needs to be dipped into soil. For demonstration purposes, a glass of soil can be used. When the sensor is dipped into the soil, a change in the soil moisture value will be displayed on the OLED screen. This will indicate the amount of moisture present in the soil. If the soil is dry, the values will be low, and if the soil is wet, the values will be higher.
Overview of RS485 Soil Moisture & Temperature Sensor
The RS485 soil moisture & temperature sensor is a device designed to measure the humidity and temperature of the soil. It is an ideal tool for farmers, gardeners, and other agricultural professionals who need to monitor soil conditions. The sensor is equipped with a built-in RS485 interface, which allows it to be connected to an Arduino board for data acquisition and control.
How Does the RS485 Soil Moisture & Temperature Sensor Work?
The RS485 soil moisture & temperature sensor works by measuring the electrical resistance of the soil. When the soil is wet, the electrical resistance is low, and when it is dry, the electrical resistance is high. The sensor is able to detect this resistance and convert it into a digital signal. This signal is then sent to the Arduino board, which can be used to control the device or display the data on an LCD screen.
How to Use the RS485 Soil Moisture & Temperature Sensor with Arduino?
Using the RS485 soil moisture & temperature sensor with Arduino is relatively straightforward. First, the sensor must be connected to the Arduino board via the RS485 interface. Once this is done, the Arduino board can be programmed to read the data from the sensor and display it on an LCD screen. Additionally, the Arduino board can be used to control the device, such as turning it on and off, or setting the desired temperature and humidity levels.
