AQM-1000 - 8 in 1 Air Quality Monitor

AQM-1000

Features

AQM-1000 can measrue (1) Temperature (-40 ~ 100 C), (2) Humidity (0 ~ 100%), (3-5) PM1.0/2.5/10 (0 ~ 999 ug/m3), (6) CO2 (400 ~ 5000 ppm), (7) HCHO (0 ~ 2000 ug/m3), (8) TVOC (0 ~ 5000 ug/m3). AQM-1000 displays the measured data with a 0.96″ OLED display.

AQM-1000 can transmit the measured values using (1) MQTT/WiFi, (2) WiFi and (3) LoRa techniques. Method (1) sends MQTT messages to the remote MQTT broker directly. Methods (2) requires MQTT server and method (3) requires LoRa MQTT Gateway to relay the received messages to the MQTT Server. Messages processed in the MQTT Server can be displayed in the remote PC monitor via a private VPN link.

AQM-1000 with LoRa

AQM-1000 LoRa signal consists of  sensor device name (AQM), ID number (B1 ~ Bi), Sequence number, each measured item name (CO2, PM2.5, Temperature, Humidity, HCHO, TVOC, etc.) and the associated data consecutively in JSON format. LoRa signals from each AQM-1000 are transmitted to the LoRa Gateway (LRMQ-1000).

LRMQ-1000 encapsulates the received LoRa signal into MQTT format with a predefined Topic and then retransmit the MQTT signal to the MQTT server (MQSVR) using 2.4 GHz WiFi for further processing.

MQTT Server parses each received MQTT messages into CO2, PM2.5, Temperature, Humidity, HCHO, TVOC values for each individual AQM-1000 device. The processed values can be displayed in the remote PC monitor as shown in the figures.
