Elsys LoRa outdoor versatile sensor 2 Input for ADC/PULSE counter.
The ELT-2 has the capability of solving almost any problem. It is enclosed in an IP67 box which makes it ideal for mounting outside or in extreme conditions. The ELT-2 can measure both analog or digital signals and can handle up to two external sensors simultaneously. Not only can you connect external sensors to the ELT-2, but it also has four internal sensors: temperature sensor, humidity sensor, accelerometer, and an atmospheric pressure sensor.
ELT-2 is the ideal sensor for measuring in advanced places or in extreme weather conditions. It is easy to install and configure to form your solution. ELT-2 has two generic inputs. You can configure ELT-2 for external temperature probe, pulse counting, analog-input 0-10V, digital-input, water leak, switch, distance sensor, soil moister sensor, and many more options. ELT-2 can be equipt with add on modules to get extra features like external PT1000 sensors, load cell input, or output control.
The battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate, and environmental factors. It is powered by one 3,6V AA lithium battery.
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.
