Air Monitoring PM2.5 CO2 Formaldehyde TVOC Temperature Humidity Air Quality Sensor

M702 is a multi-in-one gas alarm sensor module that can measure various kinds of gas at the same time. The sensor module incorporates CO2, formaldehyde, VOC, and a laser particle sensor. The sensor module also has a built-in temperature and humidity probe. These parameters will be unified in the form of digital interface output. The appliance sensor module by optimizing the internal structure, to reduce the size of the module, also to the sensitivity of the sensor is guaranteed.
