Small current sensor, exploring the big world of the Internet of Things Elevator IoT Chapter (2)

With the rapid development of the Internet of Things (IoT) in elevators, high-precision and highly reliable leakage current monitoring has become the core link to ensure the safe operation of elevators. Shanghai Dehuai Electronics is deeply involved in the field of industrial sensing and has launched three high-performance leakage current sensors – DXE-10mA-R10-5V, DXE10mA-R11-5V, and DXE-10mA-BM-5V – for elevator IoT scenarios. Through technological innovation, they aim to solve industry pain points and help elevator operations move from “passive response” to “active prevention”
