Resistive Soil Moisture Sensor with Corrosion Resistant Probe

Resistive Soil Moisture Sensor with Corrosion Resistant Probe

This module is a soil moisture detector sensor module + it has corrosion resistance probe which are compatible with the Arduino. This soil moisture sensor can read the amount of the moisture present in the surrounding soil.This soil moisture arduino compatible sensor uses the two probe to pass the current through the soil, as if in the soil more water is present than that soil will conduct the electricity more easily like less resistance will be offered and if the soil is dry than that soil will offer more resistance and soil conduct electricity will be poor. This Moisture Sensor can be used to detect the moisture of soil or judge if there is water around the sensor, let the plants in your garden reach out for human help. They can be very to use, just insert it into the soil and then read it. With help of this sensor, it will be realizable to make the plant remind you. if there is requirement of water or not. This module requires input supply voltage of 3.3 - 5VDC and its working current is less than 20mA. This soil humidity detection module includes a potentio meter and soil moisture thresholds.

Specification of Resistive Soil Moisture Sensor with Corrosion Resistant Probe

  • LEDs indicating output and power
  • PCB Size: 3.2cm x 1.4cm
  • LM393 based design
  • Easy to use with Micro controllers or even with normal Digital/Analog IC
  • Operating Voltage: 3.3V to 5V DC
  • Operating Current: 15mA
  • Output Digital - 0V to 5V, Adjustable trigger level from preset
  • Output Analog - 0V to 5V based on infrared radiation from fire flame falling on the sensor
  • Small, cheap and easily available

LM393 IC

LM393 Comparator IC is used as a voltage comparator in this Moisture sensor module. Pin 2 of LM393 is connected to Preset (10KΩ Pot) while pin 3 is connectedto Moisture sensor pin. The Comparator IC will compare the threshold voltage set using the preset (pin2) and the sensor pin (pin3).

Preset (Trimmer pot)

Using the onboard preset you can adjust the threshold (sensitivity) of the digital output.

Moisture Sensor

The moisture sensor consists of two probes that are used to detect the moisture of the soil. The moisture sensor probes are coated with immersion gold that protects Nickel from oxidation. These two probes are used to pass the current through the soil and then the sensor reads the resistance to get the moisture values.

How to Use Soil Moisture Sensor Module

Moisture sensor module consists of four pins i.e. VCC, GND, DO, AO. Digital out pin is connected to the output pin of LM393 comparator IC while the analog pin is connected to Moisture sensor.Using a Moisture sensor module with a microcontroller is very easy. Connect the Analog/Digital Output pin of the module to the Analog/Digital pin of Microcontroller. Connect VCC and GND pins to 5V and GND pins of Microcontroller. After that insert the probe inside the soil. When there is more water presented in the soil, it will conduct more electricity that means resistance will be low and the moisture level will be high.

Applications 

  • Irrigation Systems
  • Gardening
  • Used in Controlled Environments
