Thermometer Project Kit

The kit uses a thermistor to measure the temperature which is then displayed on an LED scale. A PIC micro-controller, pre-programmed with special software, is used to process the output of the thermistor and light the relevant LEDs.

The thermometer has two temperature ranges. One designed for indoor use and the other for outdoor use (selected by a wire link). The temperature is displayed every 10 seconds or can be displayed on demand by adding either a normally open / normally closed push button switch.
