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.
