Bluetooth Thermometer
This wireless temperature sensor is developed based on PIC12F675 microcontroller. The project is equipped with DS18B20 1-Wire temperature sensor and Sure TTL Bluetooth Module.
The advantage of using Bluetooth than Xbee module is that no custom hardware is required on the receiving end and almost all modern laptops have an integrated Bluetooth chipset, so no more hardware is required on the PC end. Bluetooth Thermometer firmware is written in PICBasic and is compiled using ProtonIDE. You can download firmware, schematic and source code here. PIC Bluetooth Thermometer is designed by Jamie Maloway
