PRODUCT DETAILS

Feature

  • Corrosion-resistant design:  Capacitive touch measurement system avoids probe oxidization. 
  • Powerful ICs embedded: NE555DR manufactured by TI working with built-in amplifier, good for capacitive measurement.
  • Plug-and-play: Grove compatible interface(data transmit) and a long-straight pad function as a probe(data collecting).
  • Starter-friendly: Detail start-up tutorials,  abundant resources and projects provided in Wiki and Community. 

Description

The Grove - Capacitive Moisture Sensor (Corrosion Resistant) is a soil moisture sensor based on capacitance changes.  Compared with resistive sensors, capacitive sensors do not require direct exposure to the metal electrodes, which can significantly reduce the erosion of the electrodes. Hence, we call it Corrosion Resistant

It is important to note that this sensor can only qualitatively test the humidity of the soil and cannot measure quantitatively. This means when the humidity of the soil rises, the value of the output decreases; conversely, when the humidity decreases, the output value becomes higher.

Note

We've Released the Grove Selection Guide and hope to help you find the Grove that suit you best. 

Applications

  • Botanical Gardening
  • Moisture Sensoring
  • Consistency Measurement
