Elsys LoRa EMS-Door sensor - Monitor Acceleration / Door Activity

This is an indoor LoRaWAN® opening activity sensor that will tell you when an object has been opened or moved. It is a subtle and minimalistic sensor and the size is ideal for mounting on door frames, window panes, cabinets, and much more.  

With a size slightly larger than an AA-battery, EMS Door is one of our most subtle sensor yet. EMS Door can be used as a opening activity sensor or for movement detection. The small size makes it ideal for mounting on door frames, windowpanes or other small surface areas.

Movement detection

Inside EMS Door you will find internal sensors for detecting when something has moved. Typical for door activation but the application scope is bigger than that. The minimal magnet is designed to be mounted on the part that may move and the EMS Door close to it on something fixed

All our sensors are built on the LoRaWAN stack from Semtech. Channel plans for US902-928, EU863-870, AS923, AU915-928, KR920-923.

Sensor startup

When the sensor starts up it loads configuration from the internal memory  and merge it with user configuration. When the configuration is done the sensor writes the new configuration to the NFC chip. The sensor always writes new configurations to the NFC chip when something changes in the sensor or if NFC data is corrupted by a NFC writer or phone. The sensor always writes new configuration to NFC chip at startup. When configuration is done the sensor tries to join the network if OTAA (Over The Air Activation) is enabled.The sensor led flashes orange  when it tries to join a network. The sensor tries to join the network every 10 second and increases the join timer at every failed attempt by 10%,  up to maximum 1 hour. After startup,configuration and join the sensor enters sampling mode.

ERS

NFC read/write

When reading or writing NFC data to the sensor, it starts a timer and delays its actions for 5 seconds. This delay is for the possible bad connection inherited with NFC communication. Reasons for bad connection can be distance, location or rapid movement. After the delay, the sensor determines if the NFC data has changed or not. If the data has change the sensor reboots and starts from power up. When writing data to the sensor, try to get the best connectivity as possible. Locate the NFC antenna of the phone and sensor. Keep the 2 devices as close as possible and don’t move them while writing or reading. When you have written data to the sensor, let the sensor reboot and restart before trying to write again. You can always validate your settings by reading the NFC data after the sensor has restarted.
