Reliable data transmission at -26 °C/-14.8 °F

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

• Consistent Performance: Sensors functioned flawlessly through multiple extreme weather events, delivering accurate, uninterrupted data.

• Operational Efficiency: Real-time monitoring enabled just-in-time collection, removing waste containers only when full.

• Asset Visibility: GPS tracking ensured visibility of each sensor’s location, mitigating confusion when bins were relocated.

Future Outlook

Following the success of the pilot, the City of Lethbridge is already actively planning to scale the solution, installing additional sensors across more locations and monitoring other waste streams.

The case study will be continuously enhanced with new key achievements and results as further data becomes available.
