Zhengzhou Winsen Electronics Technology Co., Ltd Pins Definition Pins Definition PIN1 Remarks The ZPH03's two mode settings can only be performed before the sensor is normally powered on. Please make a hardware connection in advance. In UART mode, Pin4 is serial port data transmitter In PWM mode, Pin4 is output of PWM Email: [email protected] Leading gas sensing solutions supplier in China!

Zhengzhou Winsen Electronics Technology Co., Ltd Application Circuit 1. PWM Mode Application Circuit 2. UART Mode Application Circuit Remarks: The sensor has two output modes: PWM or UART, which are set in factory. Email: [email protected] Leading gas sensing solutions supplier in China!

Zhengzhou Winsen Electronics Technology Co., Ltd PWM Mode In PWM mode, the sensor outputs PWM signal through PWM port (PIN 4). The PWM cycle is 1s, and the dust concentration value is calculated according to the width of low level. The low pulse width of PIN output corresponds to the average value of dust concentration. The value of concentration was processed by software filtering, and the pulsation amplitude was relatively small. Remarks：1. LT : the pulse width of low level in one period.(unit: ms) 2. UT : the pulse width of one period(unit: ms) 3. The low pulse rate: RT=LT/ UT × 100% 4. The...

Zhengzhou Winsen Electronics Technology Co., Ltd Cautions 1.Terms of Use 1.1 Installation Sketch Installation Board 3. Installation suggestions 2.1 the sensor should be installed in the air circulation position to avoid contact with organic solvents; 2.2 recommended air velocity: (1.0 ~ 3) m / s; air volume: 0.004 ~ 0.01 CMM; 2.3 it is recommended to keep the sensor terminal downward; 2.4 it is recommended to add 3-5mm thick black breathable filter cotton at the air inlet side of the sensor to prevent the accumulation of dust and other large particles; 2.5 it is recommended to keep away from...

Zhengzhou Winsen Electronics Technology Co., Ltd 3.2 To avoid strong electromagnetic interference, the sensor has certain anti-interference performance, but it should still avoid strong electromagnetic environment. When using wireless communication module (such as WiFi, Bluetooth, GPRS, etc.), it is necessary to keep a sufficient distance from the sensor, and the specific safe distance shall be verified by the user. 4.Transport & storage 1. Avoid vibration：Frequent transport and assembly process, excessive vibration will lead to optical device dislocation affect the original calibration data...
