WS201
The WS201 tells cleaning teams when a tissue or paper-towel dispenser is running low, replacing scheduled checks with visits only where they are needed. A time-of-flight sensor measures the remaining stack from 1 to 55 cm to ±1 cm and reports the percentage left over LoRaWAN, with alarm thresholds you set. At 66 by 38 by 12 mm it sticks inside almost any dispenser with adhesive tape, a damp-proof internal coating suits humid washrooms, and it works inside metal housings. A single CR2450 coin cell runs for around 3.2 years, configured by NFC from a phone. Typical uses are washrooms in airports, hotels, shopping centres and visitor attractions.

Requires a LoRaWAN Gateway
WS201 sends its data over LoRaWAN, so it needs a LoRaWAN Gateway in range. Works with any LoRaWAN Gateway, such as the UG65. If you already have a Gateway on site, you can skip this.
