❖ Description ❖
――――――――――――――――
In this tutorial, we will look at How to make "Heat Sensor Circuit using Thermistor" Step by Step completely
Simple heat sensor circuit designed to give alert sound when the temperature reaches the desired threshold, here we can adjust the temperature threshold level using Variable resistor RV1. This simple circuit is easy to construct and test.
This circuit utilize NTC (Negative Temperature Coefficient) thermistor hence the Resistance value of this device decrease when the temperature rises.
