Have you ever wondered what the temperature was in your garage, attic, porch or anywhere in your home? A small, energy-efficient wireless temperature sensor enables the consumer to better understand their environment and adjust their environmental controls accordingly. This reference design can help kick-start your own connected home, smart appliances or smart energy designs.
The Wireless Temperature Sensor reference design is part of our Connected Home platform. At the heart of the design is a low-power nanoWatt XLP 16-bit PIC® microcontroller, the PIC24F32KA302. The MCP9808 temperature sensor has an operation range from −40°C to +125°C. The temperature data is transmitted via the MRF89XAM8A/9A sub-GHz wireless module. Two AA batteries provide power to the board.
