This is an indoor LoRaWAN® room sensor for measuring the indoor environment, the number of openings on a door, or maybe if something has moved or not. It also has a water leak detector which makes it ideal to mount under a dishwasher, for example. With its small size and minimalistic design, it is perfect for mounting on door frames, window panes, or any other limited surface area. If you need a discrete looking sensor with a broad scope of application, EMS is the one for you.
