With this Smart Bluetooth hygrometer you can easily measure the ambient temperature and humidity.
Thanks to its compact size (49.5mm x 49.5mm), this smart hygrometer can easily be placed near your 3D printer, (bath) room or storage boxes for food or cigars, for example. Simply set the min-max values via the matching app and receive a notification when the temperature or humidity falls outside this range. The values are stored on the meter for up to 100 days. This way you are always informed.
