Detect bad odour in public toilets

Smart Washroom Odour Monitoring System

Replace fixed cleaning rosters with data-driven hygiene management.

A janitor who works in the same washroom every day stops noticing the odour — that's human physiology, not negligence. And when one janitor covers multiple washrooms, there is no reliable way to know which one needs attention right now. A fixed schedule cleans washrooms that don't need it and misses ones that do.

The Ahoy Washroom Sensor measures odorous gas concentration and temperature/humidity continuously, delivering a real-time hygiene quotient and ppm value for every monitored washroom to a centralised dashboard and mobile app. Supervisors dispatch janitors when and where conditions actually demand it — not when the clock says so.

Complete Washroom Intelligence with Footfall Counting

The sensor pairs with the Ahoy Footfall Counter — laser-based, no cameras, full privacy compliance. Usage data combined with odour levels enables genuinely dynamic rostering: high-footfall washrooms get more frequent attention automatically, low-traffic ones are cleaned only when needed. The result is fewer janitor-hours wasted and zero missed incidents.
