Elsys Mini Sensor. Our most minimalistic andsubtle sensor yet. 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 detectorwhich 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 broadscope of application, EMS is the one for you.
