Overview :

The SM300D2 seven-in-one sensor module is a cost-effective digital serial output sensor module. It uses both RS485 data bus and UART serial port TTL level output modes, collecting CO2, formaldehyde, TVOC, laser PM2.5, PM10, temperature , Humidity in one. It can carry out real-time comprehensive detection of the environment in which it is located, and has good stability.

Features :

● Simultaneous output of carbon dioxide, formaldehyde, TVOC, PM2.5, PM10, temperature, humidity seven sets of data

● High sensitivity and stable data

● At the same time, it adopts two output modes of RS485 bus and UART TTL level, which is convenient for customers to choose and use independently.

● The temperature is accurate to 0.1 ℃, and the humidity is accurate to 0.1% RH

● Automatically output these seven sets of monitoring data via RS485 interface every second

● With power supply anti-reverse protection function

Application :

● Hotel room air quality monitoring

● Environmental monitoring of agricultural greenhouses and outdoor breeding sites

● Fresh air ventilation system

● Air purifier, air conditioner

● Air quality monitoring equipment

● Kitchen and bathroom ventilation control system

● Smart home equipment

Sample Data :

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 result is obtained:

Checksum	B17=unit_8(3Ch+02h+08h+0FCh+00h+79h+01h+D7h+00h+13h+00h+22h+1Bh+03h+30h+02h)=18h
CO2	B3256+B4=08h256+0FCh=2300ppm
eCO2	B5256+B6=00h256+79h=121ug/m3
TVOC	B7256+B8=01h256+0D7h=471ug/m3
PM2.5	B9256+B10=00h256+13h=19ug/m3
PM10	B11256+B12=00h256+22h=34ug/m3
Temperature integer	B13=1Bh=27℃
Decimal temperature	B140.1=03h0.1=0.3℃
Humidity integer	B15=30h=48%RH
Humidity decimal	B160.1=02h0.1=0.2%RH

Note:

The CO2 value and CH2O value output by the module are the equivalent values of TVOC. Please pay attention when buying and using.
