Evaluating the Main Unit - Three Years On

 

Three years ago for this project we created an initial group of five trial units.  These units were intended to test the concept but also served the purpose of seeing if we could remain water tight (assuming there would always be some moisture entering the units) and if the unit would continue to operate with the battery and the set up.

Of the initial five units we have deliberately kept one remaining in its original state including having the original solar panel and battery.

Three years later the unit is still operating and still activating every minute or so when fully charged.  Although the solar panel is battered it is still operating and able to charge the unit.   The cellphone battery that is charged via the panel is still operating and working as intended.   The original electronics are more or less intact.

We would remain confident that this unit as deployed in its updated state could be operating in external conditions and would do so correctly and without the need for maintenance or updating etc.
