Simple Heat Sensor Circuit using a Single Transistor
To begin with, this Simple Heat Sensor Circuit using a Single Transistor and one special resistor like thermometer. When it get hot this resistor changes to how it work because of which the transistor sees this change; also the transistor work like a door and if temperature changes it opens or closes for electric. So […]
