Soil Moisture Sensor Detector Module Soil Moisture Humidity Test Sensor with 1.3M Cable
This soil moisture sensor module is designed to measure the moisture content in the soil, providing an output that reflects the soil’s water volume. The module offers both digital and analog outputs, along with an adjustable potentiometer to set the desired moisture threshold.
Featuring a waterproof sensor probe with excellent corrosion resistance, this sensor is built to last, ensuring a minimum operational life of 6 months when used in soil.
Brief about Soil Moisture Sensor Module
This Moisture sensor module consists of a Moisture sensor, Resistors, Capacitor, Potentiometer, Comparator LM393 IC, Power and Status LED in an integrated circuit.
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 connected to Moisture sensor pin. The comparator IC will compare the threshold voltage set using the preset (pin2) and the sensor pin (pin3).
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.
Preset (Trimmer pot)
Using the onboard preset you can adjust the threshold (sensitivity) of the digital output.
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. The internal Circuit diagram of the Moisture sensor module is given below.
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.
