PMS5003 High Precision Laser Dust Sensor Module PM2.5 PM10 Air Quality Detection
Overview
PMS5003 is a digital general-purpose particle concentration sensor based on the principle of laser scattering. It can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume, that is, the particle concentration distribution, which is then converted into mass concentration, and the general number
Interface format output.
This sensor can be embedded in various instruments and meters or environmental improvement equipment related to the concentration of suspended particles in the air to provide timely and accurate concentration data.
Main features
1. The principle of laser scattering realizes accurate measurement
2. Zero false alarm rate
3. Real-time response and support continuous acquisition
4. The minimum resolution particle size is 0.3μ m
5. Brand new patented structure, six-sided all-round shielding, stronger anti-interference performance
6. The direction of the air inlet and outlet is optional, the application range is wide, and the user does not need to design the air duct.
Working principle
This sensor uses the principle of laser scattering.
Even if the laser is irradiated on the suspended particles in the air, the scattered light is collected at a certain angle to obtain the curve of the scattered light intensity with time.
Furthermore, the microprocessor uses an algorithm based on MIE theory to obtain the equivalent particle size of the particles and the number of particles of different sizes per unit volume.

Circuit design should pay attention
1. PMS5003 needs 5V power supply because the fan needs 5V drive.
But other data communication and control pins all need 3.3V as high level.
Therefore, the motherboard MCU connected to the communication should be 3.3V power supply.
If the motherboard MCU is powered by 5V, a level conversion chip or circuit should be added to the communication lines (RXD, TXD) and control lines (SET, RESET).
2. SET and RESET have internal pull-up resistors, if they are not used, they should be left floating.
3. PIN7 and PIN8 are used for internal debugging of the program and should be left floating in the application circuit.
4. Note when applying the sleep function: the fan stops working during sleep, and it takes at least 30 seconds to stabilize the fan to restart. Therefore, in order to obtain accurate data, the sensor working time should not be less than 30 seconds after sleep wakeup.
