Understanding NTC Thermistor
NTC thermistor is a temperature sensor that changes its resistance in accordance with the temperature. It comprises a small resistor that is used to detect the temperature of a particular component or pipe. The resistance of the thermistor can be determined by measuring it. In the case of an NTC thermistor, the resistance is usually around 10 kilms. When the thermistor is heated, the resistance drops immediately. This is in contrast to a PTC thermistor, which increases its resistance when heated.
Connecting NTC Thermistor to Arduino
In order to connect an NTC thermistor to an Arduino, one must first create a bridge between the thermistor and a normal resistor. This bridge is then connected to the Arduino board. The Arduino board is then programmed to read the resistance of the thermistor. The resistance is then used to calculate the temperature of the component or pipe that the thermistor is attached to.
Calculating Temperature with Arduino
Once the thermistor is connected to the Arduino board, the board can be programmed to calculate the temperature of the component or pipe. This is done by measuring the resistance of the thermistor and then using the Steinhart-Hart equation to calculate the temperature. The equation takes into account the resistance of the thermistor, the temperature coefficient of the thermistor, and the ambient temperature. Once the temperature is calculated, it can be displayed on an LCD screen or sent to a computer for further analysis.
Understanding NTC Thermistor
NTC thermistors are temperature-sensitive resistors that exhibit a decrease in resistance when the temperature increases. These devices are commonly used in temperature sensing applications, as they are highly accurate and reliable. The resistance of an NTC thermistor is determined by its material composition and the temperature of its environment. The resistance of an NTC thermistor is typically expressed in ohms ().
Connecting NTC Thermistor to Arduino
Connecting an NTC thermistor to an Arduino is a relatively simple process. First, a 10K ohm resistor must be connected to the thermistor. This is done by connecting one end of the resistor to the thermistor and the other end to the 5V pin on the Arduino. The other end of the thermistor is then connected to the ground pin on the Arduino. Once the thermistor is connected, the Arduino can be programmed to measure the resistance of the thermistor and calculate the temperature.
Measuring Resistance
In order to measure the resistance of the thermistor, the Arduino must be programmed to read the voltage across the thermistor. This can be done by using the analogRead() function. This function will read the voltage across the thermistor and return a value between 0 and 1023. This value can then be used to calculate the resistance of the thermistor.
Calculating Temperature
Once the resistance of the thermistor has been measured, the temperature can be calculated. This is done by using the Steinhart-Hart equation. This equation takes the measured resistance of the thermistor and returns the temperature of the environment. The equation can be programmed into the Arduino and used to calculate the temperature.
Connecting NTC Thermistor to Arduino
The NTC thermistor is a temperature-sensing device that can be connected to an Arduino board to measure temperature. The thermistor is connected to the Arduino board through a voltage divider circuit, which is composed of two resistors and the thermistor. The two resistors are connected in series to the 5V and GND pins of the Arduino board, while the thermistor is connected to the middle pin of the voltage divider circuit. The output of the voltage divider circuit is connected to the analog input pin of the Arduino board.
Creating the Voltage Divider Circuit
The voltage divider circuit is created by connecting two resistors and the thermistor in series between the 5V and GND pins of the Arduino board. The two resistors are connected in series to the 5V and GND pins of the Arduino board, while the thermistor is connected to the middle pin of the voltage divider circuit. The output of the voltage divider circuit is connected to the analog input pin of the Arduino board.
Writing the Code
Once the voltage divider circuit is created, the next step is to write the code to read the temperature from the thermistor. The code should read the analog voltage from the analog input pin of the Arduino board and convert it to temperature. The code should also be able to display the temperature in degree Celsius, Fahrenheit, or Kelvin. There are several code examples available online, which can be used as a starting point for writing the code.
Testing the Circuit
Once the code is written, the circuit can be tested by connecting the Arduino board to a computer and uploading the code to the board. The output of the voltage divider circuit can be monitored using the serial monitor of the Arduino IDE. The voltage should decrease when the thermistor is touched, indicating that the circuit is working correctly.
