Applied technology is full of physical parameters, like temperature, humidity, pressure, you name it. Each of them influencing our todays or tomorrows lifes to the good or bad. Often the important issue "When, How long and at Which intensities did it happen?" gets, due to not available low-cost technical instrumentations, a proper answer.

The economic price of Euro ¤66.-/ logger makes this affordable to the DIY person for his home or for a climate control engineer to monitor a pharmaceutical plant with hundreds of "temperature sensitive locations". That the DataPick®s might travel with ESA into space is probably not a price issue. Example of an earthbound application: The heating / climate control system of a building complex with 100 apartments must be balanced for proper energy distribution.
