Abstract

The invention provides a coal gas sensor with ZigBee wireless intelligent transmission. The coal gas sensor with ZigBee wireless intelligent transmission comprises a power supply, a coal gas sensor, arelay controller, a ZigBee template and an early warning template. The power supply provides power for the coal gas sensor, the relay controller, the ZigBee template and the early warning template; the relay controller is used for receiving information of the coal gas sensor and converting the information into a ZigBee signal; the coal gas sensor comprises a gas sensor and a sampling circuit; andthe ZigBee template comprises a ZigBee master control circuit, an information power amplifier, a radio frequency antenna, an external Flash unit and a crystal oscillator circuit. The early warning template comprises an input module, a buzzer, an alarm lamp and a gas valve.

Description

technical field [0001] The invention relates to a gas sensor, in particular to a gas sensor with ZigBee wireless intelligent transmission. Background technique [0002] With the promotion of gas in the vast number of families, gas safety issues also follow, and the gas sensor came into being to solve this problem, it is the last protection for the safe use of city gas. The gas leakage sensor detects low-concentration combustible gas in the surrounding environment through the gas sensor, and transmits the detection signal to the controller or control circuit with analog or digital quantities through the sampling circuit. When the value is set, the controller sends an alarm signal through the actuator or the executive circuit or performs actions such as closing the gas valve. The combustible gas alarm detects combustible gas sensors mainly include oxide semiconductor type, catalytic combustion type, and hot wire type gas sensors. There are also a small number of other types s...
