Features  Good long-term stability  Good consistency  High sensitivity  Rich interface output methods  Easy to install and maintain Applications Air purifier Air refresher Air ventilating device Air conditioner Technical Parameters Portable...

Zhengzhou Winsen Electronics Technology Co., Ltd Basic dimensions Detection Principle Heater Leading gas sensing solutions supplier in China!

Zhengzhou Winsen Electronics Technology Co., Ltd Remarks The ZPH01B dust sensor uses a power resistor to heat the air, and the rising of the hot air drives the ambient gas (PM2.5) into the detection light path to perform detection. The optical structure determines that the installation and placement of the sensor have certain specifications, otherwise it will cause abnormal detection data. Pins Definition UART model Control pin(refer the detailed instructions) Remarks The two modes of ZPH01B can only be set before the sensor is normally energized. Please make the hardware connection in advance....

Packing box 2: 630×280×405mm, can fit 20×2×19=760 sensors Matters needing attention when using the sensor Terms of Use 1. Installation requirements: The sensor is installed vertically to ensure a smooth detection gas path and avoid contact with organic solvents. 1.1 Must be installed vertically. The sensor as a whole must be fixed and...

Zhengzhou Winsen Electronics Technology Co., Ltd 1.2 Ensure a smooth detection air path. The external air flow can enter the optical cavity of the sensor smoothly and be discharged in time. When applied to an air cleaner, the air flow of the fan cannot affect the stability of the air path detected by the sensor, and it can be installed on one side of the body. 1.3 Avoid light The dust sensor uses a specific wavelength light LED and a photoelectric sensor with visible light to detect dust particles. The external light radiation will affect the optical signal of the dust sensor. It is recommended...
