Product category：Sensors
Product model：LoRaWAN-BGPM10
Product Overview:
PM2.5 is particulate matter in the atmosphere with diameter of 2.5 micrometer or less. Particulate larger than 10 microns are kept out of human nose. Particulate between 2.5-10 microns can enter the upper respiratory tract., but some can be excreted through sputum. However, particulate smaller than 2.5 microns is easy to be inhaled into the bronchial tube, which interferes with the exchange of gas in the lungs, and causes diseases including asthma, bronchitis and cardiovascular diseases.
Product Features:
● Follow standard LoRaWAN communication protocol.
● Able to collect data of PM1.0, PM2.5, PM10.
● Using LoRaWAN wireless communication method to complete data interaction with main station.
● Transmission power is automatically adjusted.
● Automatic network access and smart frequency hopping.
● Ultra-long communication distance and fast access to network.
● Automatic crystal oscillator temperature compensation. Stable and reliable communication.
● Low-power design for energy conservation and environmental protection.
