Recently the company wanted to do a PM2.5 testing equipment, probably studied the PM2.5 related knowledge, as well as sharp dn7c3a006 sensor applications.The following is a brief introduction to it.1, its own dust-free voltage (nodust_v), the nominal temperature (base_temp), the two values are scanned by a QR code, such as the scan we purchased to obtain the "149190104F 1.31 * * * * 25.8", can be obtained nodust_v = 1310mv, Base_temp = 25.8 ℃ (but the
As an environmental data monitoring station, the first step is to obtain the data of respirable particulate matter in the atmosphere. In order to detect PM25 data, we use the HLPM025K3 model sensor, the Beijing Maritime Union, which uses a laser method to measure PM25 and PM10 data.This type of sensor detects the following objects:M2.5: Measuring 0.3-2.5 micron particulate matter in air;PM10: Measures 0.3-1
