Product Name: Laser Particle Counting Sensor Module Item No.: PM5000S Version: V0.2 Date: 6th Sept, 2023

Laser Particle Counting Sensor ModulePM5000S Applications Clean Room Pharmaceuticals Industry Precision Machinery Industry Microbiological Industry PM5000S laser particle counting sensor module is based on laser scattering technology, which can accurately detect and calculate the number of suspended particles with different particle sizes in the air. The sensor can simultaneously output quantity of particles in 6 channels including 0.3um, 0.5um, 1.0um, 2.5um, 5.0um and 10um (PCS/L). ■ Constant current sampling structure, ensure the even sampling flow ■ Better laser diode and strong fan with better...

Product Installation The surface of air inlet and air outlet closing to inner wall of user machine, this is the best installing method. If cannot do like this, there should be air isolation structure between inlet and outlet, thus to avoid the air flow return in the machine. The appropriate installation ways are recommended as below. Recommended installation Internal profile

User Attentions ※ When install the product in your system or equipment, please make sure of unobstructed air-inlet and air-outlet. And make sure that there is no huge airflow faced to air-inlet and air-outlet. Please follow the recommended installation to avoid dust deposit on the sensitive elements surface. ※ The inside diameter of user equipment’s air inlet should not be smaller than the product’s air inlet diameter. ※ When applying to air purifier, the product should be avoid being installed directly in the air duct. Or there should be a structure room to isolate the product in the air duct....

UART Communication ProtocolI.General Statement 1) The data in this protocol is all hexadecimal data. For example, “46” for decimal [70]. 2) [xx] is for single-byte data (unsigned, 0-255); for double data, high byte is in front of low byte. 3) Baud rate: 9600; Data Bits: 8; Stop Bits: 1; Parity: No 4) It is default by continuously mode after powering on. Working mode will not be saved after powering off. Sending format of software: 4.1 Read Particle Measurement Result Send: 11 02 0B 07 DB Response: 16 35 0B DF1- DF52 [CS] Function: Read measurement result.

Note: Read particles number (pcs/L). Note: Part of reserved bit is used for our internal testing. The data changeable of reserved bit is nothing related to function. 4.2 Open/Close Particle Measurement Send: 11 03 0C DF1 1E CS Response: 16 02 0C DF1 CS Function: Open/ close particle measurement 1. When sending command, DF1=02 means opening measurement, DF1=01 means closing measurement; 2. When receiving response, DF1=02 means measuring opened, DF1=01 means measuring closed; 3. When the sensor receives the command of opening measurement, it will be in default continuous testing mode.

CUBIC Example: Response: 16 02 0C 02 DA //module is under particle measurement open status Response: 16 02 0C 01 DB // module is under particle measurement closed status 4.3 Set up and Read Particle calibration coefficient Send: 11 02 07 DF1 CS // Set up particle calibrated coefficient Send: 11 01 07 E7 // Read particle calibrated coefficient Response: 16 02 07 DF1 CS Function: Read/set up particle calibration coefficient Calibration coefficient setting valid range: 0.1~2.5. Function: Read software version Should change the HEX code to ASCII code.

a. This is an I2C protocol for PM5000S. The sensor module is lower computer, which is not able to initiate communication automatically. Communication is initiated via main controlled board, which reads data and sends control commands. b. Communication clock frequency <=100Khz START: start signal, send by main controlled board; STOP: stop signal, send by main controlled board; ACK: acknowledge signal, send by the sensor module if in bold; otherwise, send by main controlled board; NACK: non-acknowledge signal, send by the sensor module if in bold; otherwise, send by main controlled board; Px: receive...
