Eight-in-one Air Quality Module RS485 and TTL typeDescriptionThe RK14V seven-in-one air quality module is a cost-effective digital serial port output sensor module, using serial TTL level output mode, integrating CO2, formaldehyde, TVOC, laser PM2.5, PM1.0, PM10, temperature and humidity in one. It can conduct real-time and comprehensive detection of the environment, has good stability, and is very convenient for customers to use.
ApplicationHotel room air quality monitoring
Fresh air ventilation system
Air purifier, air conditioner
Air quality monitoring equipment
Kitchen and bathroom ventilation control system
Smart home equipment
Environmental monitoring of agricultural greenhouses and outdoor breeding places
Features:Simultaneously output seven sets of data of carbon dioxide, formaldehyde, TVOC, interface every second
With power supply reverse connection protection function PM2.5, PM10, temperature and humidity
High sensitivity and stable data
RS485 bus o r UART TTL level output mode, we can also provide customized services according to customer requirements (such as RS232, WIFI,lora,Cat1).
The temperature is accurate to 0.1ºC, and the humidity is accurate to 0.1%
The seven groups of monitoring data are automatically output through the UART TTL
