Multifunctional gas integrated sensor

Abstract

The invention belongs to the field of sensors, particularly relates to a multifunctional gas integrated sensor, and aims at solving the problems that an existing gas integrated sensor is poor in heatdissipation performance, external dust easily enters the sensor in the heat dissipation process, and the service life of the gas integrated sensor is seriously affected. Themultifunctional gas integrated sensor in the following scheme comprises a sensor main body, a base is fixedly connected to the bottom of the sensor body, side boxes are fixedly connected to the two sides of the sensor body, a sealing plate is slidably and hermetically mounted in each side box, an upper plate is fixedly connected to the top of each sealing plate, first air holes are formed in the sides, away from each other,of the two side boxes, and first one-way valves are fixedly connected into the first air holes. And a first dustproof plate is fixedly connected in the first air hole. The sensor main body is good inheat dissipation effect, dustproof processing is well carried out in the heat dissipation process, and the indicator lamp can flicker intermittently during heat dissipation to remind that heat dissipation is carried out normally.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a multifunctional gas integrated sensor. Background technique [0002] An integrated sensor is a sensor made using a silicon semiconductor integration process, so it is also called a silicon sensor or a monolithic integrated sensor. The analog integrated sensor came out in the 1980s. It is a special IC that integrates the sensor on a chip and can complete the measurement and analog signal output functions. [0003] After retrieval, the application publication number is a multifunctional gas integrated sensor disclosed by CN 107907635 A, which includes a housing, an integrated chip and a sensor. Sensor, negative ion sensor and carbon monoxide sensor, described PM2.5 sensor, VOC sensor, temperature sensor, humidity sensor, negative ion sensor and carbon monoxide sensor are respectively connected with described integrated chip correspondingly, described PM2.5 sensor, VOC sensor, te...
