Basic Info

Model NO.
HW300D2
HW300D2 Four-in-one Air detection sensor module is a cost-effective digital serial port output sensor module. It uses RS485 data bus and UART serial port TTL level two output modes, integrating laser PM2.5, PM10, temperature and humidity. It provides real-time and comprehensive detection of the environment, with good stability and is very convenient for customers.
Pm2.5, Pm10, Temperature and Humidity Sensor

Application areas:
Hotel room air quality monitoring
Agricultural greenhouses, outdoor farming environment monitoring
Fresh air ventilation system
Air purifier, air conditioner
Air quality monitoring equipment
Kitchen and bathroom ventilation control system
Smart home equipment
Features:
Simultaneously output four sets of data of PM2.5, PM10, temperature and humidity
High sensitivity and stable data
Simultaneously adopt RS485 bus and UART TTL level two output modes, which is convenient for customers to choose and use.
 Temperature is accurate to 0.1 °C, humidity is accurate to 0.1%

Data example:
For example, if the value read is 3C 02 08 FC 00 79 01 D7 00 13 00 22 1B 03 30 02 18, the following results are obtained:
ChecksumB17=unit_8(3Ch+02h+08h+0FCh+00h+79h+01h+D7h+00h+13h+00h+22h+1Bh+03h+30h+02h)=18h
PM2.5B9*256+B10=00h*256+13h=19ug/m3
PM10B11*256+B12=00h*256+22h=34ug/m3
Temperature integerB13=1Bh=27ºC
Temperature fractionB14*0.1=03h*0.1=0.3ºC
Humidity integerB15=30h=48%RH
Humidity decimalB16*0.1=02h*0.1=0.2%RH
