Case Studies
Explore case studies showcasing how our products deliver reliable monitoring, seamless integration, and measurable results across diverse industries.

Biotech Cold Storage Facility, Boston, MA
A biotech firm required high-accuracy temperature loggers for vaccine storage across its Northeastern U.S. distribution sites. Environmental Telemetry Devices supplied solar-powered LoRaWAN-compatible loggers with customizable alert thresholds. These devices ensured 24/7 compliance and avoided $2M in potential losses from temperature excursions.
Museum Preservation Project, Denver, CO
A large heritage museum in Colorado implemented our Zigbee-enabled humidity loggers to protect rare documents and artifacts. The loggers provided continuous environmental data to a local BMS and issued alerts to facility managers during seasonal fluctuations.


Agricultural Greenhouses, Ontario
A commercial greenhouse in Ontario integrated our Wi-Fi HaLow-based temperature and humidity sensors to optimize plant growth environments. With real-time feedback and local display units, the business increased crop yields by 12% within the first growing cycle.
