LoRaWAN Current Sensor Kit for Remote Monitoring of Factory Equipment Current Levels

No complicated wiring is required, maintenance costs are reduced due to the built-in battery, monitoring is possible via smartphones and PCs, and it can also be used for current monitoring in buildings and offices.

LoRaWAN Wireless Communication Features ■ Low Power Consumption: The power consumption varies slightly depending on the end device, but it has a fast transmission and reception speed, and consumes less power compared to other communication standards, which helps reduce maintenance frequency. Additionally, it consumes so little power that two-way communication can be achieved with just one button battery, and it is said that such batteries can last over 10 years in continuous operation under optimal conditions. ■ Long-Distance Communication: The range of the 800MHz band used by smartphones (3G and later) is said to be about 2 to 5 km, but with LoRaWAN, communication is possible over a distance of about 10 km, more than double that. In areas with few obstacles, communication over distances greater than 10 km is possible; however, for practical use in urban areas, it is advisable to expect a range of about 3 to 5 km, and about 1 km in indoor environments with obstacles. ■ High Noise Resistance: The 920MHz band used by LoRaWAN is less susceptible to interference from other wireless networks, allowing for reduced communication latency and stable communication. Therefore, it can be safely utilized in factory facilities and indoor environments.
