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:
- Atmel Attiny10.
- Generic set diode.
- Lithium-Ion coin battery
