Module10: Digital Temperature Sensor(SE017)
1．Introduction
This module has both analog signal output pin and digital signal output pin, which is
different from analog temperature sensor(module33) and other temperature sensor
module.
A thermistor is a type of resistor whose resistance is dependent on temperature, more
so than in standard resistors. The word is a portmanteau of thermal and resistor.
Thermistors are widely used as inrush current limiter, temperature sensors (NTC type
