| Abstract: | It is absolutely necessary to have a methane density detector in the working of coal mine.Now a new-type methane density detector is put forward which is based on non-dispersive infrared spectrum absorptive fundamentals.In this design scheme,the key elements are a sensor named MSH-HC/TC manufactured by DYNAMENT and a MCU marked MSP430F157.The operational principle of the infrared methane sensors,hardware and software implementation schemes of the methane density detector are introduced in detail.The experim... |
