70MHz Soil Sensor
jhns-de/70MHz-Soil-Sensor
Soil moisture and electrical conductivity (EC) sensor based on 70 MHz impedance measurement, developed as part of my master’s thesis.
Boards in 3 GitHub repositories, designed in KiCad, that use the APHD1608LCGCK by Kingbright (-40℃~+85℃ 1.9V 100° 2mA 570nm 574nm 75mW 8mcd Discrete Diode Water Clear Yellow Green LED0603 LED Indication - Discrete ROHS). See how each wires it, with its parts, size, README and files; the APHD1608LCGCK’s symbol, footprint and pinout are on its own page.
