    • RE: 💬 Soil Moisture Sensor

      Try to never try resistive sensors. It is reaaly wrong way. I try to bult few resistive. No way.
      I try to buld some inductive. Yes, it's possible, but lot of analog parts, difficult to calibrate. No way too.
      Capacitive senors is most reliable and has a simple digital schematics.

      Good luck you on your way)

      PS: here is my own sensor http://vegimatics.com/products/current/
      want do discuss - wellcome)

    • RE: nRF24L01+ RF_CH bits

      RF_CH bits are used to select channel. Channel number and frequence calculated like this: F = 2400 + RF_CH.

      And some usefull table.
