LM35 is a Low-cost temperature sensor. Consisting three legs namely Vcc Out and Ground.
It shows an increase in output voltage with respect to the temperature of the surroundings.
Detailed datasheet can be found here
Vcc can be connected to evive’s Vcc to provide higher logic level to the Temperature sensor.
Ground is provided to common the lower voltage level.
Output goes to the analog pin of evive (in our case A0) to read it’s status.
