How to use

Project Seven - Temperature

Next on our Grove journey is the temperature sensor . It is an analog form of input, and as described

earlier returns a voltage potential relative to the ambient temperature. We measure this voltage using

an analog pin, and convert it to a temperature.

Connect the Temperature Sensor to the Analog A0/A1 input jack. The Grove unit produces an analog

voltage on its D1 output, which is connected to Arduino A0 analog input on the A0/A1 input jack.

int del=1000; // duration between temperature readings

void setup() { Serial.begin(9600); } void loop() { a=analogRead(0); resistance=(float)(1023-a)*10000/a; temperature=1/(log(resistance/10000)/B+1/298.15)-273.15; delay(del); Serial.println(temperature); } You can copy and paste the lines above to add temperature capability to your own sketches.
