The challenge
What the system had to solve
Reliable data transfer
Measurements need a defined path from the sensor through a nearby gateway to cloud storage and dashboards.
Maintenance at a distance
Supported devices need a way to receive firmware updates without routine on-site access.
The solution
How the system was structured
Efficient ESP32 firmware
The sensor wakes, measures, transmits and returns to a low-power state; achievable battery life depends on the configured usage profile.
BLE and cloud connection
Bluetooth Low Energy carries measurements to a gateway, which forwards them to the cloud data layer.
Dashboard and remote updates
The interface presents current measurements, configured thresholds and history, with remote firmware support where the hardware permits it.
