A leading developer of ventilation systems wanted to develop wireless and smart solutions. The solution developed aims to produce a control system of smart ventilation valves and pressure measurement devices over LoRa® network. Remote monitoring and controllable valves are used to balance and boost the airflows in and out of a building keeping the indoor ‘climate’ fresh.
Provides smart, demand-controlled exhaust ventilation for apartment buildings by automatically adjusting the ventilation according to the rhythm of living to the desired/ideal level
Balances the apartment-specific ventilation to the target air volumes resulting in healthy, draft-free and fresh indoor air
The LoRa® network connectivity is provided by a MultiTech Conduit unit acting as a forwarder and gateway between the room devices and the Central Unit (CU), which is responsible for controlling the gateway, authenticating & authorizing the LoRa® devices into the network and storing the uplink messages into a persistent database
The frontend admin application makes requests behind the scenes directly to the backend i.e. API layer, which communicates with the database services and room devices
