Senseca has introduced the LoRaWAN technology-driven LR35 data logger series designed specifically for situations requiring long-range transmission.

The technology offers ultralow-power consumption, with battery life that lasts up to four years while delivering a transmission range of several kilometers.

“This is a different technology to measurement systems that are built using a sensor with direct LoRa communications. Senseca chose to use data loggers with LoRa communication, which means that the measurement data can always be recovered, even in the case of failing transmission. We believe it makes the LR35 series the best choice for a wide range of demanding applications across all industries,” said Senseca South Africa MD Jan Grobler.

The LR35 loggers are used in a range of applications such as smart cities, smart buildings, air quality assessment, agriculture, solar, soil, food and medicine storage, production, transportation, and solar power. The LoRaWAN technology is best suited for measurements that are independent from external power and where high-speed transmission is not required.

The data loggers feature sensors that measure conditions such as temperature, humidity, differential pressure, CO2 and particulate matter. The wireless devices are used for Internet of Things applications that use LoRaWAN technology and the unlicensed frequencies of the ISM band such as EU868, US915, AU915.

In areas where LoRa coverage is available, the loggers can be connected to a free public gateway or used with a customer’s own commercially-available gateway to connect by means of WiFi, Ethernet, 3G or 4G.

The LR35 series is preconfigured to send data to the free-to-use network server, the so-called ‘The Things Network’, and the data sent by the sensors is visible through a third-party Cloud application of the Senseca Cloud service.

“The LR35 series is simple in operation, has no cabling in-between units, and offers a superior long range transmission facility with free Cloud access. Should a customer require a private gateway, we can advise on several types and brands to work with,” added Grobler.
