Smoke sensor

Abstract

The invention provides a smoke sensor which comprises a smoke sensor module, a signal processor, an output module and a display module. The smoke sensor module is used for detecting smoke density signals; the output end of the smoke sensor module is connected with a signal amplification module for amplifying the detected smoke density signals; the output end of the signal amplification module is connected with the input end of the signal processor for processing the smoke density signals; the output end of the signal processor is connected with the display module for displaying the processed smoke density signals; and the output end of the signal processor is connected with the output module for synchronizing the generated signals to a monitor room. The output end of the existing smoke sensor module is provided with an anti-interference circuit for filtering the interference of the collected smoke density; by amplifying the filtered smoke density, the smoke density parameters obtained finally are allowed to be more accurate; and meanwhile, when the smoke is little or thin, the smoke density can be collected normally, and accurate detection is achieved.

Description

technical field [0001] The invention relates to the technical field of type testing, in particular to a smoke sensor. Background technique [0002] A sensor is a detection device that can detect the measured information and convert the detected information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. Sensors are the primary link to realize automatic detection and automatic control, mainly including photoelectric sensors, acoustic sensors, temperature sensors, humidity sensors, smoke sensors, etc. [0003] In the prior art, the sensor mainly includes a power supply, a sensor module and a micro control unit (MCU, MicroControlUnit), wherein the power supply is used to supply power to the sensor module and the MCU, and the sensor module collects data for the parameters to be measured, and sends the coll...
