Bluetooth-enabled personal thermometer with Arduino
Technologist and self-proclaimed geek Dr Michael Proll has created a simple thermometer and humidity-reporting device that can be polled via bluetooth to retrieve the current sensor values. The hardware is based on his low-energy bluetooth shield and our Freetronics Eleven board. Operation is by sending ASCII characters from an iPhone via bluetooth, which then receives the required data and displays it on the iBLE application on the iPhone.

If you're looking for a sensor to measure temperature and humidity - check out ourHUMID: humidity and temperature sensor module. Designed around the DHT22 sensor, it only requires one digital pin and power - and is easy to use with out Quick Start guide. With a temperature range of -4°C to +125°C with +/-0.5°C accuracy, and humidity at 0-100% with 2-5% accuracy you're ready to measure. For more information and to order, click here.
