The data loggers of the LR35… series are wireless devices for IoT (Internet of Things) applications that use LoRaWAN® technology for long distance data transmission.

LoRaWAN® technology uses the unlicensed frequencies of the ISM band (for example EU868, US915, AU915, KR920, AS923, IN865) and allows a transmission range of several kilometers depending on the installation position and the urbanization condition of the place where the network infrastructure is located, with extremely limited energy consumption, allowing long operation of battery-powered devices.

With the LR35… series, we provides a wide range of loggers with sensors for all general measurement conditions like temperature, humidity, differential pressure, CO2, PM.

For outdoor applications, we have specific IP67 loggers with connections to pyranometers, rain gauges and soil moisture.

But also we connect any other third party measurement with LoRa as long as it has a standard output: 4-20mA, 0-10V, Modbus-RTU.
