Product and brands

Our brand is Wiljami

The Wiljami grain moisture meter / hygrometer continuously measures the corn humidity and temperature in real time in the dryer. The drying process can be monitored and controlled in real time with a smartphone or computer. Wiljami's smart IoT solution ensures exactly the right grain humidity. Remote monitoring and remote readability together with automated stopping of drying make the farmer’s life easier and free up time for other tasks.
Wiljami Technologies Oy has purchased the business pertaining to Wiljami corn hygrometry from PehuTec Oy. The business acquisition was carried out on 18 April 2019. The Wiljami grain moisture meter / hygrometer is an IoT-based product that facilitates the day-to-day operations of corn farmers and generates time and cost savings in grain drying. Wiljami Technologies Oy will further develop, sell and market IoT devices.
Digitalisation will be an important part of the future of our society, and PehuTec, the company that developed the Wiljami product, has succeeded in developing a successful IoT product for measuring corn humidity. Wiljami Technologies Oy will further develop the product for an international breakthrough.
