80 mhz MEMS oscillator Capacative soil sensor designed and routed in Kicad, the capacative probe is calculated to be between 1-70pF and uses a Festel BT840 nrf5284 system on chip zigbe bt5.0 module
The design is derived from from /u/bahildebrand/soil-moisture-pcb with an external 80mhz oscillator, added NTC tempsensor and a two prong coplanar capacative probe design.
