For the problem of temperature drift, inexact and great transmission loss of the monitoring of environment temperature and humidity under the mine, this paper proposes the temperature and humidity monitoring and optical fiber communication transmission system under the mine based on TMS320LF2812(DSP) by controlling the digital temperature sensor. The system adopts RS232 serial communication, uploads data by optical communication. Data are dealed with by host computer to improve the speed and capability of system .The actual test results show that the system can work stably ,the measuring accuracy of temperature and humidity is up to 0.1 and 1%RH. It can realize reliable data transmission.
