Design of Underground Gas Concentration and Humidity Monitoring System Based on RS-485

Abstract:

In order to achieve long distance monitoring of gas concentration and humidity underground coal mine,a new monitor of gas concentration and humidity,which contains upper computer,master station and a lot of monitoring points,is designed.Every monitoring point is consisted of gas concentration sensor MJC4/3.0L and humidity sensor HS1101,which is used to conveys the data to master station by RS-485,again by RS-485 transmitted to the upper computer and it realizes the real-time monitoring of gas concentration and humidity undereground coal mine.
