Block Diagram - Precise wireless temperature sensor powers itself
In case you missed it, LTC’s Kris Lokere recently wrote an article for EDN describing a circuit combining Dust, Energy Harvesting, and precision temperature sensing. Specifically, it describes a reference circuit showcasing:
- Dust Networks wireless - LTP5901-IPM SmartMesh IP Mote
- Energy Harvesting - LTC3330 Nanopower Buck-Boost DC/DC, which in this circuit has a main cell and solar cell for battery life extension
- Precision temperature sensing - LTC2484 24-bit delta sigma ADC, sampling a thermistor
- Voltage Reference - LTC6654, which is duty-cycled by the circuit for low average current draw
