SM300D2 7-in-1 PM2.5 PM10 Temperature Humidity CO2 formaldehyde TVOC Sensor +

Detail 

 
Description:
 
 
SM300D2 seven-in-one sensor module is a high cost-effective digital serial output sensor module. It uses two output modes, RS485 data bus and UART serial TTL level. It integrates CO2, formaldehyde, TVOC, laser PM2.5, PM10, temperature and humidity. It can real-time and comprehensive detection of the environment, has good stability, very convenient for customers to use.
 
Application area:

Air quality control in hotel rooms
Environmental monitoring of agricultural greenhouses and outdoor farming sites
Fresh air ventilation system
Air purifier, air conditioning
Air quality monitoring equipment
Air exchange control system for kitchen and toilet
Intelligent Home Appliances
 
Characteristic:
Export carbon dioxide, formaldehyde, TVOC, PM2.5, PM10, temperature and humidity at the same time.
High sensitivity and data stability
Two output modes, RS485 bus and UART TTL level, are adopted to facilitate customers to choose and use them independently.
Temperature accuracy to 0.1 C, humidity accuracy to 0.1% RH
Seven sets of monitoring data are automatically output per second through RS485 interface
With anti-backconnection protection function of power supply
