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
