Abstract

The invention discloses a vehicle-mounted laser PM2.5 sensor. The vehicle-mounted laser PM2.5 sensor comprises a shell, an air inlet and an air outlet are formed in the shell and are respectively located on the opposite two side walls of the shell, an air induction fan is arranged in the air outlet, an air induction interface is arranged in the air inlet, an air induction pipe connector is arranged on the air induction interface, an air exhaust interface is arranged in the air outlet, and an air exhaust pipe connector is arranged on the air exhaust interface. The air induction interface, the air exhaust interface and the internally arranged air induction fan are arranged, so that the air in or outside a vehicle is introduced into the inner part of the sensor, the concentration of dust in the air is then detected through laser, then the air is exhausted into or outside the vehicle through the fan, the air exhaust interface and an externally arranged air exhaust pipeline, air induction equipment is not additionally added, an external connection pipeline is adopted, and the vehicle-mounted laser PM2.5 sensor is not limited by the installation position, is good in airtightness, is notaffected by external air speed, and is strong in anti-jamming capability and high in detection accuracy, and the detection result is reliable.

Description

technical field

[0001] The invention relates to the technical field of laser dust sensors, in particular to a vehicle-mounted laser PM2.5 sensor. Background technique

[0002] With the continuous deterioration of the environment, the detection of dust concentration has become increasingly necessary in various industries and even people's lives, and the demand will become larger and larger. As the core component of laser dust detection instruments, the performance of laser dust sensors is crucial to The quality of the testing instrument has a decisive influence. Existing PM2.5 sensors are mainly used in civilian purifiers, and they are all used in a static state. If the PM2.5 sensor is placed on the car, there will be the following problems: 1. The suction of the built-in fan in the car is too small, and the external airflow It is difficult to pass through the detection area of ​​the sensor stably and evenly, so that the detection of the sensor is easily affected by the exte...
