We now have a limited number of iB004 PLUS beacons in stock with an additional SHT20 temperature/humidity sensor. The iB004 is one of the most commonly used (and re-branded) beacons and the ‘PLUS’ part means it has a larger CR2477 battery rather than the CR2450 in the original iB004. The larger battery means there’s a longer 100m (vs 70m) range and longer battery life.

The temperature/humidity version has a small hole in the top to allow the environment, external to the case, to be sensed.
