Abstract :
In the data gathering for the signal of dual-channel about Infrared Methane Sensor, the accuracy of 12-bit ADC embed in MCU can reach 14 -bit by Over-sampling, it improves the performance of system, make the system meet the demand for intrinsic Safety and reduce production costs. This paper describes the over-sampling technique and its implementation of hardware and software in the detection system of Infrared Methane Sensor.
