LoRaWAN Leak Detection Sensor Kit Remote monitoring of water leaks and flooding.

No complicated wiring is required, maintenance costs are reduced due to the built-in battery, monitoring is possible with smartphones and PCs, and it also protects server rooms and assets.

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, which is said to last over 10 years of continuous operation in some cases. ■ 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 distances of about 10 km, more than double that. In locations 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 prone to interference from other wireless networks, even in environments where they exist, which helps minimize communication latency and allows for stable communication. Therefore, it can be safely utilized in factory facilities and indoors.
