Laser Particle Sensor ModulePM3003Q Applications ■ Industrial PM Monitoring ■ Factory Particulate Emission monitoring ■ Mining Site Dust Monitoring ■ Environment PM Monitoring Alarm System The PM3003Q laser dust sensor module adopts the principle of optical scattering, which can accurately detect and calculate the number of suspended particles of different particle sizes in the air per unit volume. Real-time output of PM2.5, PM10, TSP mass concentration ■ Industrial grade laser with high reliability ■ Anti-dust design, meet the measurement of high dust environment ■ Small size, easy to install...

*Gold Sample traceable instrument is TSI8533, calibrated in ISO 12103-1 A2 test dust environment www.gassensor.com.cn

Table 2. Connector Pin Definition

Typical Application Circuit 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 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 Sending format of software:

CUBIC 4. Detail Description of UART Protocol 3.1 Read Particle Measurement Result Function: Read concentration of particle and particles number. Note: Read particle concentration (pg/m3) Note: Part of reserved bit is used for internal testing. Reserved bit is not related to function www.gassensor.com.cn

User Attention ※ It is the best installation method that the plane where the air inlet and outlet are located is close to the air hole connecting the inner wall of the user machine with the outside world. If this is not possible, there should be a structure between the air inlet and outlet to isolate the air flow in and out, so as to prevent the air from flowing back inside the user machine. ※ When this product is installed and used in the system, the air inlet and air outlet should be unobstructed, and there should be no large airflow facing the air inlet and outlet; the internal section of...
