Shengshi IoT PMS5003T particulate matter sensor PM2.5 sensor

working principle

PMS5003T is a digital universal particle sensor based on the principle of laser scattering. It can continuously collect and calculate the number of suspended particles of different particle sizes in the air per unit volume, that is, the particle concentration distribution, and then convert it into mass concentration, and use a universal digital interface form output. This sensor can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particles in the air, providing timely and accurate concentration data.

This sensor uses the principle of laser scattering. That is, the laser is irradiated on suspended particles in the air to cause scattering, and the scattered light is collected at a specific angle to obtain a curve of the scattered light intensity changing with time. Then, the microprocessor uses an algorithm based on the Michaelis-Menten (MIE) theory to obtain the equivalent particle size of the particles and the number of particles of different sizes per unit volume.
