Accurate Monitoring with ToF Technology
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.
Flexible Paper Remaining Alerts
Optimize alerts and notifications for paper supply by implementing customizable threshold levels for greater flexibility.
Tailored Construction for Compactness
Ultra-thin body design effectively saves deployment space and adapts to various sizes of toilet paper boxes
Simplified Convenience at Its Finest
1 DevEUI QR code on the front for quick scanning
2 Buckle-open lid design for easy maintenance
Schedule Hibernate Mode to align with scenarios such as mall closing and office hours ending.
Ultra Low Power Consumption
The WS201 is powered by a long-lasting coin cell battery that can last up to 2 years. This ensures uninterrupted usage and eliminates the need for frequent battery replacements.
