IoT LoRaWAN® data logger for environmental monitoring, LR35 serie

Long-range environmental data collection becomes simpler when each measuring point can work wirelessly and with low power demand. The LR35 series records measured values and transmits them via LoRaWAN®, making it suitable for IoT monitoring in smart buildings, agriculture, solar sites, storage, transport and environmental observation.

Data remains available even if transmission is interrupted, because the logger function keeps a backup of measurements. The series supports public or private LoRaWAN® networks and is preconfigured for The Things Network, while measured values can be viewed through Senseca Cloud or third-party cloud services.

The family covers a wide range of measuring tasks, from temperature, humidity, differential pressure, CO2 and PM to solar radiation, rain, soil VWC, analog inputs and Modbus-RTU sensor integration. Indoor and outdoor versions are available, with outdoor models rated IP 67 and designed for -20...+70 °C / 0...100 %RH conditions.

Long-range data
LoRaWAN® transmission reaches several kilometers, depending on installation conditions.

Flexible networks
Connects to public or private LoRaWAN® networks and is preconfigured for TTN.

Outdoor options
Outdoor models offer IP 67 protection for -20...+70 °C / 0...100 %RH conditions.

Backup built in
Logging function keeps measurement data recoverable if transmission fails.

Broad sensor choice
Covers temperature, humidity, CO2, PM, rain, solar, soil and standard inputs.

Low-power operation
Battery-powered models offer typical autonomy up to 4 years, depending on version and intervals.

Features

• LoRaWAN® communication
  The data loggers use LoRaWAN® technology for long-distance wireless transmission in IoT measurement systems and can be integrated into existing public or private networks.
• Measurement logging
  The series includes a logging function that stores measurement data locally, allowing data recovery when wireless transmission is unavailable or interrupted.
• Sensor and input variants
  The product family includes models for environmental quantities and interfaces such as temperature, relative humidity, differential pressure, CO2, PM, solar radiation, rain, soil VWC, analog inputs and RS485 Modbus-RTU.
• Network configuration
  The loggers are factory configured for The Things Network and support OTAA and ABP activation methods, with AES128 data encryption.
• Cloud data access
  Measurement data can be viewed through Senseca Cloud or third-party cloud services, depending on the selected system configuration and data protocol.
• Display versions
  Depending on the model, the series offers versions without display, with custom LCD or with graphic LCD for viewing measured values and device status.
• Interval settings
  Measuring intervals and transmitting intervals are configurable, with measuring intervals from seconds to minutes and transmitting intervals starting from 2 minutes.
• Installation variants
  Indoor models are intended for wall installation, while outdoor models can be wall mounted or installed on a mast with suitable accessories.
