Abstract
The utility model relates to a smoke detection module comprising a smoke sensing circuit and a single chip microcomputer control circuit, wherein an output signal of the smoke sensing circuit is transmitted to an A/D data conversion circuit, an output signal of the A/D conversion circuit is transmitted to the single chip microcomputer control circuit, and an output signal of the single chip microcomputer control circuit is sent to an optical coupling linkage circuit. According to the smoke detection module, analog-to-digital conversion is carried out by using a voltage value output by a smoke sensor, the voltage value is output to a single chip microcomputer system for processing, and gas concentration changes are converted into different digital outputs through a signal conditioning circuit. The smoke detection module has the advantages of being highly integrated, stable in performance and simple in control and is widely used in fire monitoring and alarming systems.
Description
Technical field
The utility model relates to a kind of detecting module, particularly be a kind of smoke detection module.
Background technology
