Problems solved by technology

However, when the airflow is continuously separated by the filter membrane for a long time, the substances collected on the filter membrane will cause the loss of volatile and semi-volatile substances with the change of airflow and temperature; The pore size of the membrane or the dust baffle is determined. At the same time, the composition of the air has changed after passing through the separation part, and the sensor does not measure the real-time dust particle value.

Abstract

The present invention discloses a high-accuracy dust monitoring apparatus, which comprises: a first dust sensor (1) and a second dust sensor (2), wherein the first dust sensor (1) and the second dust sensor (2) are respectively used for obtaining dust particles with a particle size of more than 1 [mu]m and a particle size of more than 2.5 [mu]m; a microcontroller (3) respectively connected to the first dust sensor (1) and the second dust sensor (2); and a WiFi module (4) connected to the microcontroller (3) and used for receiving data processed by the microcontroller (3) and transmitting to a server through a network.

Description

technical field [0001] The invention relates to the field of air quality collection and monitoring, in particular to a high-accuracy dust monitoring device. Background technique [0002] Existing detection methods for dust particles include: gravimetric method, micro-oscillating balance method, β-ray method, optical principle sensor method, etc. Among them, the existing sensor method is mainly to filter and remove particles larger than 2.5 microns in the air through the separation part, and the outlet end of the particle separation part is connected with the inlet end of the dust particle detection sensor, so as to realize the measurement of the dust particle parameters in the air . However, when the airflow is continuously separated by the filter membrane for a long time, the substances collected on the filter membrane will cause the loss of volatile and semi-volatile substances with the change of airflow and temperature; The pore size of the membrane or the dust baffle i...
