The basic principle of combustible gas detection is introduced from the working principle of TGS813 sensor.Low-power single-chip MSP430F149 is taken as the main controller of the hardware.TGS813 sensor is used to achieve signal acquisition.The part of wireless data transmission is designed by NRF905 chip.Measured value influenced by temperature were amended in the software part

which improved measurement precision

and controlled the communication module to achieve wireless data transmission.The experiments show that the precision of the system is higher than ±5 %F.S.

and wireless transporting distance of 330 meters can be achieved in open area.This system can meet most industries’ needs.
