It is used to monitor air parameters (dust, CO2, temperature, humidity) with data transmission via the Lora radio channel. To receive this data, a 7bit AirGate gateway (or AirGate Combo) must be used, which converts the data received via the Lora radio channel from many modules into MQTT protocol packets and transmits them further to an MQTT broker (server) on a local network or the Internet.
7bit AirPoint – Q
Air quality monitoring module with Lora
Applications
- dispatching systems for buildings, fitness centers, etc.
- warehouses, vegetable storage facilities
- other industrial facilities
Overview of functions
In general, the system consists of one or more wireless, stand-alone 7Bit Airpoint radio modules and 7Bit Airgate data gateway(s) that receive messages over the radio channel and transmit them to any upper-level system, such as a WebHMI, SCADA second or cloud-based IoT platforms such as : Amazon AWS, Microsoft Azure, and others, over a local network or over the Internet, using the MQTT protocol.
The module has sensors with a fairly high consumption, so it is powered by 220V. At the signal of the internal timer, the device performs measurements and transmits the data to the Lora channel, and then goes into standby mode again. To test the module, a special button is provided on the printed circuit board, after pressing which the module performs measurements immediately. To identify data from many devices in the upper-level data collection system, the module adds its Id (hardware address) to the data packet.
The following parameters are measured:
- Dust: measuring ranges 0.3 – 1 µm, 1.0 – 2.5 µm, 2.5 – 10 µm.
- СО2: 400 – 2000 ppm
- Temperature 40° + 125 °C
- Humidity 0 – 100%
- Fastest possible deployment of the data collection system
- Availability of diagnostic metrics for system debugging
- Ready-made templates to add to your WebHMI project
