Delta Ohm has recently released the LR35 series of long-range data loggers that feature a range of several kilometres and up to four years of battery life.

Indoor and outdoor (IP67) versions are available. Measurement parameters include temperature, relative humidity, CO₂, PM DP and solar energy. An optional display (LCD) is available for both indoor and outdoor versions.

Transmission from the data logger can be collected and viewed in a variety of ways including cloud-based platforms (Delta Ohm and third party), public gateways and commercial gateways (connected through Wi-Fi, Ethernet and 4G) and ‘The Things Network’ — an open source, decentralised infrastructure for the IoT.

Applications include environmental monitoring, agricultural applications (soil moisture, rain and solar), food and pharmaceutical manufacturing, storage and transport, solar farms, solar power and sunshine conditions.
