nRF52805 temperature sensor
A Bluetooth LE temperature beacon on a flexible printed circuit, so the antenna and the sensor can reach outside the box the battery stays in — away from the radio shadow of an enclosure and from the heat of the electronics doing the measuring. Nordic nRF52805 and a TMP117, off one coin cell. KiCad sources and Zephyr firmware.
