Smart thermometers are not the cheapest gadgets around but if you have a Raspberry Pi 3 model B mini PC gathering dust or fancy a new project this weekend you might be interested in this Raspberry Pi smart thermostat created by Hackster.io member Attila Tőkés. Equipped with Bluetooth low energy connectivity and created with the NXP Rapid IoT kit the Raspberry Pi smart thermostat also provides data logging enabling you to track your energy usage.
The Smart Thermostat will measure the temperature, relative humidity, air pressure and ambient light, all readings are then broadcast over Bluetooth and the Raspberry Pi provides visualization for the display, data logging systems as well as control the heating system.
