Measures active energy, voltage, current, active power, power factor, and grid frequency (optional: reactive energy and reactive power). Shows active energy consumption with a clear digital screen. Pulse LED: Indicates energy metering pulses. Power LED: Shows power supply status. Supports wired RS485 networks for remote meter reading and centralized management. Compatible with MODBUS-RTU or DLT645 protocols. Configurable with LoRaWAN/NB-IoT/4G/WiFi modules for flexible IoT connectivity.

The HKT-UDS100 is a smart bin sensor, independently developed and designed by Hunan HKT Technology Co., Ltd. It measures bin fill levels periodically and sends the data to nearby LoRaWAN gateways, which then forward it to the cloud. When a bin reaches the set threshold, the system sends an alert so operators can schedule collections only when needed — instead of sticking to fixed routes. The sensor also comes with GPS for tracking bin locations and temperature compensation to keep readings steady outdoors. Used in public trash cans, waste sorting stations, and similar setups.

The LoRaWAN Solenoid Valve Controller, features dual solenoid valve interfaces and employs LoRaWAN network communication for the operation of solenoid valve switches.
