1000ma Battery Tuya Air Quality Sensor 5V DC For HCHO VOC CO2

Tuya WiFi Smart Multi-function Air Quality Monitor CO2/ PM2.5/ PM1.0/ PM10/ TVOC/ HCHO/ Temperature/Humidity Tuya Smart Life

Product Introduction

This product is IoT smart home system device. It can simultaneously measure PM2.5, HCHO, VOC, CO2, temperature and humidity in the air. With a big LCD display and powered by lithium battery, it can be moved to measure the air quality in different positions. WiFi communication, TUYA cloud platform, and mobile APP ensure users to check the environmental air quality anytime.

Working principle

PM2.5 detector adopts laser scattering principle. If laser scattering on the suspended particles in the air, at the same time at a specific angle collect the scattered light, get the curve of the scattering intensity changes over time, reuse algorithm based on the theory of the MIE (MIE), it is concluded that the equivalent grain size of particles of different size particles per unit volume and concentration.

Measuring Function

The detector can detect and display the concentration value of PM1.0, PM2.5, PM10, HCHO, VOC, CO2,. According to different concentrations, LCD display screen and LED light will show different colors.

Temperature and Humidity Measurement

The detector can measure and show environmental temperature and humidity.
