Multi parameter environmental air quality sensor

Model: WCME301 series

Product Introduction

The WCME301 series multi parameter ambient air quality sensor is developed based on Weiqin Sensing's self-developed SensorEdge intelligent sensor platform. It can simultaneously detect multiple physical quantities such as PM2.5, PM10, CO2, VOC, formaldehyde, temperature, humidity, etc. It has good performance such as high accuracy, anti electromagnetic interference, and low power consumption, and can be used for environmental monitoring applications in office, home and other scenarios.

Features

1、It can simultaneously measure various physical quantities such as PM2.5, PM10, CO2, VOC, formaldehyde, temperature, humidity, etc;

2、Working temperature of -10~50 ° C, suitable for use in most office and home environments;

3、RS485 digital communication, with a long communication distance and the ability to connect to platform systems;

4、New circuit design with strong resistance to electromagnetic interference;
