Environmental sensors
Particulate, CO₂ and environmental sensing in the Air design, with additional gas channels considered for future expansion.
Useful monitoring depends on the complete signal path: sensors, embedded processing, power, communication and the application that presents the data.

Acconeer A121 is the selected radar concept for non-contact level sensing. Installation and measurement behaviour require validation.
Embedded electronics acquire readings, apply validation and prepare data for communication. Local buffering is part of the platform direction.
LoRa is the radio modulation; LoRaWAN adds a network protocol. A LoRaWAN deployment also needs suitable gateways and a network server.
Connectivity options are selected by product. BLE is a possible provisioning path; cellular may provide backhaul where local networks are unavailable.
Measurement intervals, radio duty cycle, battery capacity and charging design are assessed together. Battery life is not yet specified.
The planned data model carries device identity, site context, units, timestamps and measurement validity. Missing readings should remain missing, rather than appearing as zero or normal conditions.
Secure device identity, encrypted transport and access control must be implemented before the connected platform enters production.
Power, mounting, measurement interval and connectivity are the starting points for a useful monitoring system.
