About this product

Description

  • Supports Gravity 3-Pin Interface
  • Analog Output
  • Includes an on-board voltage regulator
  • Compatible with low-voltage MCUs

The Gravity Moisture Sensor - Corrosion Resistant measures soil mositure levels by capacitive sensing, rather than resistive sensing like other types of moisture sensor.  It is made of a corrosion resistant materal giving it a long service life. Insert it into soil and impress your friends with the real-time soil moisture data!

What's Included

  • Capacitive Soil Moisture Sensor x1
  • Analog Sensor Cable x1

Specifications

  • Operating Voltage: 3.3 ~ 5.5 VDC
  • Output Voltage: 0 ~ 3.0VDC
  • Interface: PH2.0-3P

Dimensions

  • Dimension: 98mm * 23mm (3.86in x 0.905in)
  • Weight: 15g

Very good product

Review by Eric

Reading moisture for weeks now... and very good results.

good sensor

Review by Mckenzie

This product works well. It is expensive when compared with resistance soil moisture sensors. So far no signs of degradation with the capacitor based system while the resistance based systen suffers from electrolysis.

One of the best moisture sensor.

Review by PaulGuil

After comparaisons and many reading/testing with other type of moisture sensors , this Capacitive sensor provide the best soil humidity reading. Given the way it is build , I am sure that this sensor will last for longer in the garden for few years.
Compare to resistive sensor where the plating got corroded fast and they need to be replaced more often.

Fast delivery , as usual by RobotShop people !

Would need more info

Review by George

By buying this I thought that I would get a sensor that would deliver 0-3v, depending on ground moisture. I am currently using a competitor product that does just that but for a much higher price.

When measuring the output, in the air and in the water, I never get the 0-3v range. I understand that this might be a calibration thing but then, if you want to use the sensor just with a relay board (no arduino, no programming). Just reading the voltage.

Why don't I get that range ?
How can I calibrate the sensor ?
