The Elsys EMS Door LoRaWAN Door Sensor is probably the smallest and most cost-effective LoRaWAN sensor available for motion monitoring. This device contains a door sensor (reed switch) and accelerometer within a small enclosure the size of a AA battery (21.2 x 74.9 x 20.8 mm). 

REQUIRES one ER14505 Lithium Battery.   Please add to the basket.

Perfect size and style for discrete monitoring of door opening and closing, as well as the ability to monitor the movement of items for that extra layer of security and information. It runs off a single AA sized lithium-Ion battery capable of 10 years of performance.

Our sensors are easy to deploy, with a range of mounting options and user-replaceable batteries offering wire-free installation. They are powered by one 3,6V AA lithium battery. The Battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate, power output and environmental factors. All our Elsys sensors are equipped with NFC for easy configuration with an Android phone. With this NFC application, you can change sample rate, data rate, encryption keys, triggers, activation and much more. All of the sensors are built on the LoRaWAN stack from Semtech.

Configuration: All of the Elsys LoRaWAN Sensors can be self-configured using the Android NFC app “SensorSettings“ available from Android Play. We also offer pre-configuration of sensors and gateways to your choice of The Things Network, private LNS, IoT Platform or other services. Contact us for more information.

Frequency and Certification: All our sensors are CE certified, and available for any region including US902-928, EU863-870, AS923, AU915-928 and KR920-923. Deceleration of Conformity for EU, compliance with FCC Rules and Canada licence-exempt – available on request.

Batteries: Professional EVE lithium ION batteries are recommended given reliable performance across varying temperatures and humidity.  Transport restrictions for batteries may delay some shipments.
