Mine-used Intrinsic Safety Temperature Sensor Based on PIC MCU

This article proposed a new temperature sensor design idea based on PIC MCU, band-gap temperature sensor, CAN bus communication, remote sensor supply, slow start switching power supply and other technologies, and analyzed its design principle and provided software design flow chart. A universal temperature sensor which can access to current monitor system was implemented, it can also be used as a new-type temperature sensor for self-sustaining bus distributed real time temperature detection system.
