The Moisture Sensor Probe is a fork-like physical package that easily inserts into soil or other soft, non-corrosive media. This sensor uses conductivity to detect the amount of moisture between the probes. The likely use of this sensor is in potted plants, micro-farming research and with some non-soil environments.

The single analog output may be directly connected to the Propeller Activity Board 4-channel A/D converter or easily interfaced with the MCP3002 A/D with a FLiP Multicore Microcontroller.

The quickest way to connect these to your microcontroller is using the Parallax 3-pin cables, available in a set or as individual lengths.

Moisture Sensor Probe Features:
  • 1.5 inch detection depth reaches below the top layer of media
  • 2 to 5 volt analog output is easy to read by many controllers or A/D converters
  • 9 inch (22 cm) 3-pin female-female extension cable included
Moisture Sensor Probe Application Ideas:
  • Flower and plant soil moisture measurement
  • Automatic watering system — combine with the Mini Liquid Level Sensor for a watering system
  • Non-soil applications are possible with sponges, damp paper towels and other materials
