Most electronic thermometers require the use of wired temperature sensors. This involves uncomfortably pulling the wires through the rooms. However, it is possible to use remote sensors, where the temperature measurement result is transmitted via radio.
In the presented project as a wireless link, the Bluetooth standard is used. As a broadcasting part, the Bluegiga BT WT12 module was used. Thanks to this, making a thermometer is easy even for less experienced electronics. The readout of measured values is possible on any computer also equipped with a BT connection.
The device is particularly recommended in places where a temperature measurement is uncomfortable
