The EM500-UDL offers highly accurate distance measurement for a variety of applications in harsh environments, such as flood monitoring, wastewater management, and level monitoring in grain or fertilizer. The measurement is based on ultrasonic waves transmitted and reflected back by nearby objects. The EM500-UDL-W050 features a distance measurement range from 0.3 m to 5 m. The EM500-UDL is designed for distance measurement of objects or level detection in harsh environments and for data transmission using LoRaWAN technology. With this low-power technology, the EM500-UDL can operate for up to 10 years on a 19,000 mAh battery. In combination with the Milesight LoRaWAN gateway and the Milesight IoT cloud solution, users can remotely and visually access all sensor data. The EM500-UDL is widely used for outdoor applications such as flood monitoring and level monitoring of grain silos. Package includes: Milesight EM500-UDL-W050.
