Typical Application Circuits Figure 2 Typical application circuit diagram of UART communication Notice for circuit design: ※The UART communication level is 3.3V. ※ PIN3, PIN4, PIN7 are the ports for internal debugging and should be left floating in the application circuit.

1) The data of this protocol are all hexadecimal data. For example, "46" is [70] in decimal; 2) [xx] is single-byte data (unsigned, 0-255); double-byte data high byte first, low byte after; 3) Baud rate: 9600, DataBits: 8, StopBits: 1, Parity: No. 4) After the mode is set, it will not be saved when power off. The power-on default is continuous mode. 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 quantity.

User Attention ※ When this product is installed and used in the system, the air inlet and outlet should be unobstructed, and there should be no large airflow facing the inlet and outlet air; the internal cross-section diagram of the sensor and the recommended installation method are as follows, so as to avoid dust deposition in the sensitive process during use. The surface of the device affects the test accuracy of the sensor. Figure 4 Internal section of the sensor Figure 5 Recommended installation method ※ The size of the ventilation hole opened for the air inlet on the inner wall of the user...
