These hygrometers are really useful for all sorts of applications around the house, but they’re a little inconvenient to mount. If you just stick them to something, you need to pull them back off to replace the battery, and the sensor openings are on the back, so mounting them flush reduces their effectiveness.
Our hygrometer holders fit perfectly and have vents around the bottom to ensure the sensors are measuring the surrounding air.
This improved Version 2 has thicker walls to improve grip and a centre hole to make screw mounting easy. Hygrometer not included.
