LoRaWAN Ultrasonic Distance Sensor Kit for Remote Monitoring of Tank Liquid Levels

No complex wiring is required, maintenance costs are reduced due to the built-in battery, monitoring is possible via smartphone or PC, and it can also be used for remote monitoring of water levels in rivers, dams, and well tanks.

LoRaWAN Wireless Communication Features ■ Low Power Consumption: The power consumption varies slightly depending on the end device, but due to its fast transmission and reception speeds, it consumes less power compared to other communication standards, which helps reduce maintenance frequency. Additionally, it consumes so little power that bidirectional communication can be achieved with just one button battery, and it is said that such batteries can last over 10 years of continuous operation in some cases. ■ Long-Distance Communication: While the range of the 800MHz band used by smartphones (3G and later) is said to be about 2 to 5 km, LoRaWAN can communicate over distances of approximately 10 km, more than double that. In areas with few obstacles, communication over distances greater than 10 km is possible, but for practical use, it is advisable to assume about 3 to 5 km in urban areas and about 1 km in indoor environments with obstacles. ■ High Noise Resistance: The 920MHz band used by LoRaWAN is less prone to simultaneous interference from other wireless networks, which helps minimize communication latency and allows for stable communication. Therefore, it can be reliably utilized in factory facilities and indoor environments.
