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

Selected parameters:

• range of measured temperatures -55 to 125 ° C
• measuring accuracy +/- 0.1 ° C
• range - up to 30 m in open space
• antenna - built-in
• ready transmission module for 2.4GHz frequency
• control of commands consisting of ASCII characters (with the IWrap stack)
• power supply - 9-15Vdc
• dimensions of the plates: 65x48mm and 40x38mm
• in the set of 2 printed circuit boards, programmed layout and documentation
