A pack of components to build 10 temperature sensors, ideal for class projects with students working in small groups.
This general-purpose temperature-sensing circuit uses a thermistor to detect changes in temperature and switches the LED on or off accordingly. The sensitivity of the circuit can be set by adjusting a potentiometer.
