Moisture sensor Give a way

This post is under editing

This was a simple project meant to be as a free giveaway piece to help clarify what we do as a business oriented around agriculture.

Note: it is not advanced or commercial grade in any way, it was meant as a free thing, using the lowest cost possible.

I think the idea is clear, what I did is using the following components to build the sensor:

1. Atmel Attiny10.
2. Generic set diode.
3. Lithium-Ion coin battery
