Product Introduction
1. Description of AS520 Air Quality Monitor
Air qualityQuantity detectorAS520The wearable air quality detection system employs a complementary process of sensor technology to provide a complete and reliable assessment of air quality for portable devices carried on the person.
Electrochemical elements, laser optical particle counter,Temperature and Humidity SensorAll are included in the system, which also integrates a highly sensitive GPS receiver and a 3-axis accelerometer. The microphone on the surface detects ambient noise. At night, the base station provides storage for the sensor unit and allows charging via a 12V power supply. The base station also has a GPRS module, appropriate antenna, and SIM card, which can transmit data saved during the day to the central monitoring station.
