Clever Logger to Gateway-to-Internet

Traditional loggers have to be manually downloaded to get their data.

Clever Logger changes that. The Bluetooth loggers broadcast their temperatures and the gateway picks them up and saves them to the internet every few minutes.

This gives you a “live” log of temperatures available on any internet device (computer, tablet, phone), anywhere in the world on the Clever Logger web site.

The website also gives you immediate alerts about problems and automatic reports to your email inbox.


Uses for humidity loggers

Whether you’re a business owner trying to maintain the quality of your perishable products, a laboratory technician safeguarding sensitive medical samples, or a curator in a museum responsible for preserving invaluable artifacts, monitoring environmental conditions is crucial. That’s where a Clever Logger humidity logger, sometimes referred to as a climate logger, comes into play.

Monitoring food and beverage quality

In the food and beverage industry, ensuring the freshness and quality of products is paramount.

From production to storage to transportation, the journey of perishables is fraught with potential hazards. The most notable among these is the risk of spoilage due to adverse temperature or humidity conditions. Here, a Clever Logger temperature logger provides a solution, maintaining a consistent record of environmental conditions during the transit of products. By doing so, it enables companies to ensure – and prove – that goods have been kept at safe, optimal conditions throughout their journey.

Healthcare and pharmaceutical applications

The healthcare and pharmaceutical sectors present another compelling case for the usage of Clever Logger humidity loggers.

Medications, vaccines, and biological samples often require very specific storage conditions. Deviations from these can render medications ineffective, or in some cases, hazardous. Thus, maintaining constant and specific temperature and humidity levels is not a luxury but a necessity. It’s here that Clever Logger data loggers prove their worth, offering the reliability, accuracy, and consistency needed to meet compliance and safety requirements.


The green thumb of indoor farming

In indoor farming and greenhouse cultivation, achieving the right balance of humidity and temperature is critical. Every plant species has its unique requirements, and satisfying these can mean the difference between a bountiful harvest and a disappointing yield. The role of a Clever Logger climate logger here is indispensable. It allows for the precise monitoring and regulation of environmental conditions, promoting optimal plant growth and reducing the chances of crop loss.

Preservation in museums and art galleries

For museums, art galleries, and archival storage facilities, preserving the integrity of their collections is a major concern. Delicate items such as artwork, ancient artifacts, and historical documents can be irrevocably damaged by fluctuations in humidity and temperature. This is where a Clever Logger data logger shines, providing the tools necessary to maintain ideal climate conditions and prevent the deterioration of priceless items.
