Product Description

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.

Application areas:

â— Hotel room air quality monitoring

â— Agricultural greenhouses, outdoor farming environment monitoring

â— Fresh air ventilation system

â— Air purifier, air conditioner

â— Air quality monitoring equipment

â— Kitchen and bathroom ventilation control system

â— Smart home equipment

Features:

â— Simultaneously output four sets of data of PM2.5, PM10, temperature and humidity

â— High sensitivity and stable data

â— Simultaneously adopt RS485 bus and UART TTL level two output modes, which is convenient for customers to choose and use.

â— Temperature is accurate to 0.1 Â°C, humidity is accurate to 0.1%

â— Automatically output these four sets of monitoring data through RS485 interface every second.

â— With power reverse protection

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:

Checksum	B17=unit_8(3Ch+02h+08h+0FCh+00h+79h+01h+D7h+00h+13h+00h+22h+1Bh+03h+30h+02h)=18h
