Moisture Sensor Funduino. This Soil MoistureSensor is a simple breakout for measuring the moisture in soil and similar materials The two large exposed pads function as probes for the sensor together acting as a variable resistor The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance.

Interfacing Soil MoistureSensor and Arduino In this tutorial we have used the Waveshare Soil MoistureSensor It has a detection length of 38mm and a working voltage of 2V5V It has a Forklike design which makes it easy to insert into the soil The analog output voltage boosts along with the soil moisture level increases.
Complete Guide to Use Soil Moisture Sensor w/ Examples
To connect the sensor in the analog mode we will need to use the analog output of the sensor When taking the analog output from the soil moisturesensor FC28 the sensor gives us a value from 0 to 1023 The moisture is measured in percentages so we will map these values from 0 to 100 and then show them on the serial monitor.
The Soil MoistureSensor measures soil moisture grace to the changes in electrical conductivity of the earth ( soil resistance increases with drought ) The electrical resistance is measured between the two electrodes of the sensor A comparator activates a digital output when a adjutable threshold is exceeded.
