The Elsys ELT-ETH is a LoRaWAN wireless sensor designed to measure indoor and outdoor environmental conditions. The device is wall-mounted and powered by a single AA lithium battery, eliminating the need for an external power source. Key technical features at a glance:
- Multiparameter Data Logging: Internally measures temperature, humidity, air pressure, and acceleration, as well as temperature and humidity via the pre-installed external SHT41 probe with a filter cup, thereby recording both ambient conditions and conditions at specific measurement points with a single device.
- Battery life: expected to last up to 10 years, which reduces maintenance intervals for hard-to-reach installations.
- Flexible Configuration: Sampling and upload intervals can be set via NFC using a smartphone or wirelessly via the LoRaWAN downlink, allowing changes to the settings without physical access to the device.
The ELT-ETH is compatible with LoRaWAN 1.0.3 and supports operation in Classes A, B, or C using the OTAA and ABP joining modes. The polycarbonate housing has an IP54 rating when installed and is therefore suitable for outdoor use. For humid environments, the datasheet recommends mounting the device facing downward so that water can drain away. A typical application is outdoor environmental monitoring in smart building projects, where the device reduces both installation and ongoing maintenance costs. The ELT-ETH LoRa is available in a single model.

The device features internal sensors for measuring temperature, humidity, atmospheric pressure, and acceleration. It also includes an external SHT41 probe for additional temperature and humidity monitoring.
Yes, the device is designed for both indoor and outdoor use. It features a polycarbonate enclosure and an IP54 protection class rating when used with the external SHT41 probe and filter cup.
The sensor is designed to function in operating temperatures ranging from -40 to 60 °C and humidity levels from 0 to 100%.
The device is powered by a single 3.6V AA Lithium battery (AA 14505). Depending on the environment and configuration, the battery can last up to 10 years.
The device intervals are fully configurable. This can be done using the Sensor Settings app via NFC or through over-the-air downlink configuration commands.
This is a battery-powered device designed specifically for wall mounting in its application environment.
