Product Introduction
Digital universal particulate matter sensor PM2.5 sensorPMS7003 Description:
PMS7003 is a digital universal particulate matter sensor based on the laser scattering principle. It can continuously collect and calculate the number of suspended particulate matter of different particle sizes in a unit volume of air, that is, the particulate matter concentration distribution, and then convert it into mass concentration, outputting it through a universal digital interface. This sensor can be embedded into various instruments or environmental improvement devices related to the concentration of suspended particulate matter in the air, providing them with timely and accurate concentration data.

Note 1: The maximum range refers to the sensor ensuring that the highest output value of the PM2.5 standard value is not less than 1000 micrograms per cubic metercubic meters. For values above 1000 micrograms per cubic meter, actual measurements shall prevail.
Note 2: The particulate matter concentration consistency data is data 2 in the communication protocol (see Appendix A) under the measurement environmental conditionsis 20°C, humidity 50%.
