About this product

The WS201 Smart Fill Level Monitoring Sensor is a wireless sensor that uses ToF technology to accurately monitor the fill levels of containers.

Key points:

The WS201 sensor utilizes ToF (Time of Flight) technology for precise distance measurement and accurate detection of toilet paper fill levels.
It offers flexible paper remaining alerts, allowing for customizable threshold levels to optimize paper supply.
The sensor has a compact design and easy maintenance features, such as a buckle-open lid design.
It is powered by a long-lasting coin cell battery that can last up to 2 years.
