Proven performance of bin sensors during harsh Canadian winters

Smart waste management in Lethbridge, Canada

Project and customer description

Sensoneo deployed an initial batch of ultrasonic sensors with CAT‑M connectivity across Lethbridge, Canada (population of circa 104,000), monitoring general waste, plastic, paper, cardboard, metal, and glass. The sensors were installed in two types of containers: 30 yd³ roll‑off bins and 6 yd³ steel units at three primary collection stands, with bins rotated among sites.

Challenge

The objective was to ensure reliable sensor performance and accurate data transmission under harsh winter conditions (down to -26 °C/-14.8 °F), while simultaneously improving collection efficiency and tracking bin relocations.

Solution

Sensoneo’s rugged ultrasonic sensors, designed to operate in extreme temperatures and resist water and shock, were chosen for their durability. Equipped with CAT‑M connectivity and integrated GPS, they provided real-time fill-level tracking along with precise location data. This is essential when bins shift between collection points.

Impact

The pilot in Lethbridge confirmed the consistent performance of Sensoneo’s sensors, which operated flawlessly even during severe winter conditions, delivering accurate and uninterrupted data. Real-time monitoring enabled just-in-time collection, ensuring that waste containers were only serviced when full, improving efficiency and reducing unnecessary trips. At the same time, integrated GPS tracking provided complete visibility of bin locations, eliminating confusion when containers were relocated between sites.
