MISSION To Better Understand and Prevent Heat Risk

Heat risk is a growing concern due to global warming and the ageing of the population. Solutions are still underdeveloped and fail to address the problem adequately.

Based on a new patented technology, Heat Warning Watch Canaria Plus intelligently adapts to each user and warns them in advance of a heat risk.

The alarm rings to keep you safe. You can take the right action at the right time: hydrate, cool off in the shade.



Canaria has over 5 months of autonomy. No need to be recharged and an extra layer of management.


Canaria uses sound and color codes to alert the user regardless of language or origin.

High Security

Canaria does not transmit any data: total respect of personal data and compatibility with high security sites.



Patented non-intrusive internal temperature evaluation technology without wave emission.


National test in France with more than 800 participants in partnership with French National Prevention Office in the Construction Industry (OPP-BTP).


Since its launch, our product has been adopted by more than 2,000 companies, contributing to the enhancement of heat risk prevention across various industries.

The alarm sound is designed to match the 4kHz frequency range, to which humans are most sensitive, allowing for immediate recognition of increased risk under heat conditions. To ensure the risk is clearly communicated, the new model incorporates a vibration feature. Additionally, the model name "Canaria" is derived from the "canary in a coal mine," historically used by miners who brought canaries in cages into tunnels to detect toxic gases before humans could, serving as a symbol of an early warning of danger.


With the impact of climate change, heat waves are becoming more intense every year, and as a result, the thermal risk is increasing. To protect against this invisible risk, there is a need for a solution that warns of the risk in a simple and effective way. Heat Warning Watch – Canaria protects all people, children, elderly or workers, who are confronted with intense heat. This is the mission that Biodata Bank has entrusted to Canaria.
