LoRaWAN SOLENOID VALVE CONTROLLER

HKT SVC-100 LoRaWAN Solenoid Valve Controller controls two valves independently via dual solenoid interfaces. Users can switch valves on/off or adjust flow remotely through the cloud platform — no need to be on site. Commands are sent from the user’s device to the cloud, then down to the controller through LoRaWAN gateways. The controller also supports local configuration via Bluetooth for initial setup or manual override. It works with most water and air valves, making it useful for agricultural irrigation, smart gardens, and similar applications.

LoRaWAN Multifunctional Ultrasonic Distance Sensor

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.
