The purpose of the project is to create a thermometer that can be plugged on any free serial port without using any programmable components such as microcontrollers.
The project shows how the FGM-3h sensor is made to create a high resolution flux gate magnetometer that is used to measure variations in the earth’s magnetic field.
A digital thermometer construction from beginning until the end is illustrated on this project with the use of an 8051 microcontroller and a thermistor.
