Connector Description The interface connector of Sensor is A2501WV-8P. The pitch is 2.5mm. The connection cable with female connector at both ends can also be customized.

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 Attention ▪ When install PM5000S sensor module 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. The inner profile and recommended installation as instruction in previous page to avoid dust deposit on the sensitive apparatus surface for the influence of the sensor accuracy. ▪ The air inlet size in the user machine’s inner wall should not be smaller than the sensor’s air inlet size. ▪ It should not be installed directly in the air duct for purifying when applied in air...

UART Communication Protocol 1.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. 2.Format of Serial Communication Protocol Sending format of software: Start Symbol Detail description on protocol format: Protocol Format Start symbol Sending by software is fixed as [11H],...

I²C Communication Protocol 1. Brief Introduction 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 2. Communication Common 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...

3.2 Read Data Command Send by main controlled board: START+READ+ACK+P1+ACK+P2+ACK+……+P32+NACK+STOP Data Device address Byte content Sensor address and read/write command This byte is 0x51 when read data Frame header Frame length Number of byte, not including length of device address (from P1 to P32, 32 bytes in total) Sensor status Status “1” Means sensor is closing. Status “2” Means sensor is under measuring. Status “7” Means the faulty, temperature is too high or too low, or fan speed is too high or too low. Status “0x80” Means measuring data is stable (only for dynamic or timing...
