Elsys LoRa outdoor versatile sensor with Ultrasonic
The ELT Ultrasonic is designed for measuring the distance. It can be placed in various environments and can work as a bin level sensor, tank level sensor, or water level under bridges, for example. Not only can you measure distance with the ELT Ultrasonic, but it also has four internal sensors: temperature sensor, humidity sensor, accelerometer, and an atmospheric pressure sensor. It is enclosed in an IP67 box which makes it ideal for mounting outside or in extreme conditions.
ELT Ultrasonic distance sensor can be placed in various environments to measure distance as well as temperature, humidity, and atmospheric pressure. It is enclosed in an IP67 box and is designed to be mounted outside. ELT Ultrasonic is the ideal sensor for measuring in advanced places or extreme weather conditions, and has the capacity of measuring with remarkably long range
All our sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. You can change the sample rate, data rate, encryption keys, triggers, activation, and much more in our application “Sensor Settings“. All our sensors are built on the LoRaWAN® stack from Semtech.

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.
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.
