Build a Bluetooth Low Energy environmental sensor with the nRF52840 — measuring temperature, humidity, and air quality with multi-day battery life and mobile app connectivity.
Platform: nRF52840
Advanced multiprotocol SoC with 1MB Flash, 256KB RAM, and USB support. The go-to chip for Bluetooth 5.4, Thread, Zigbee, and 802.15.4 applications.
Use Case: Environmental Monitor
Multi-sensor environmental monitoring station that measures temperature, humidity, air quality, and pressure, reporting data wirelessly to a central system.
Why This Combination
The nRF52840's 1MB Flash and 256KB RAM provide ample room for BLE stack, sensor drivers, and data logging. Its ultra-low-power modes enable coin cell or small battery operation.
