Smart Toilet Paper Remaining Alert for Efficient Refilling
WS201 is a wireless sensor that utilizes ToF technology to monitor the fill level of containers with high accuracy. Working with Milesight LoRaWAN® gateway and Milesight IoT Cloud, WS201 allows users to remotely monitor and manage container fill levels and status in real-time.
WS201 utilizes advanced ToF (Time of Flight) technology for precise distance measurement, ensuring accurate detection of toilet paper fill levels. Additionally, it has a minimal blind zone of only 1 cm.
Optimize alerts and notifications for paper supply by implementing customizable threshold levels for greater flexibility.
Ultra-thin body design effectively saves deployment space and adapts to various sizes of toilet paper dispensers.
