Crowtail- Thermistor Temperature Sensor

Wiki & External links

Features

• Voltage: 3.3 ~ 5V
• Max power rating at 25℃: 300mW
• Zero power resistance: 10 KΩ
• Operating temperature range: -40 ~ +125 ℃

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.
