Soil Moisture Interface (SMX)
The SMX is an interface module for sensors that measure moisture content of soil or other substrates. The SMX provides three output modes – voltage, current or frequency – allowing the sensor to easily interface with a wide range of general purpose data logging equipment and meters.
More info
  • Supply Voltage: 3.3 - 15 Vdc
  • Voltage Output: 0.2 - 1.0 volts
  • Current Output: 0.2 - 1.0 mA
  • Frequency Output: 50 Hz - 7 kHz
  • Available encapsulated or OEM

smx
