Crowtail- Thermistor Temperaturen Sensor
Contents
Description
The Crowtail- Thermistor Temperature Sensor uses a Thermistor to detect the ambient temperature. The resistance of a thermistor will increase when the ambient temperature decreases. It's this characteristic that we use to calculate the ambient temperature.The detection range of this sensor is between -40 to 125 degrees Celsius with an accuracy of ±1.5℃. However it doesn’t output the temperature value directly. To get the specific temperature value, we will use the formula in the code below.The Crowtail- Thermistor Temperaturen Sensor uses a Thermistor to detect the ambient temperature.

Usage
Here is an example to show you how to read temperature information from the sensor.
1.Connect the module to the Analog port 0 of Crowtail - Basic Shield using the 3-pin grove cable.
2. Plug the Crowtail - Basic Shield into Arduino.
3. Connect Arduino to PC by using a USB cable.
4.Upload the following sample sketch:
#include <math.h> int a; float temperature; int B=3975; //B value of the thermistor float resistance; void setup() { Serial.begin(9600); } void loop() { a=analogRead(0); resistance=(float)(1023-a)*10000/a; //get the resistance of the sensor; temperature=1/(log(resistance/10000)/B+1/298.15)-273.15;//convert to temperature via datasheet ; delay(1000); Serial.print("Current temperature is "); Serial.println(temperature); }
5.Open the serial monitor. You should see current temperature.
