Soil Hygrometer Humidity Detection Moisture Sensor for Arduino measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant, or interaction with neutrons, as a proxy for the moisture content.

Soil Hygrometer Humidity Detection Moisture Sensor measure or estimate the amount of water in the soil. These sensors can be stationary or portables such as handheld probes. Stationary sensors are placed at the predetermined locations and depths in the field, whereas portable soil moisture probes can measure soil moisture at several locations.

Nutrients in the soil solution provide the plant with the food it needs to grow. Water is also essential for regulating plant temperature through the process of transpiration. Soil moisture plays a key role in the life of the plant.

Plant root systems are better developed when growing in moist soil. Excessive levels of soil moisture, however, can lead to anaerobic conditions that can promote the growth of plant and soil pathogens.

The Soil Hygrometer Humidity Detection Moisture Sensor uses to measure the volumetric water content of soil. This makes it ideal for performing experiments in courses such as soil science, agricultural science, environmental science, horticulture, botany, and biology.

The sensor produces an output voltage according to the resistance, which by measuring we can determine the moisture level.

A better understanding of the basic principles, definitions, and terms behind the soil-water-plant relationship is essential to effectively utilize soil moisture sensors.

Simply insert this rugged sensor into the soil to test, and the volumetric water content of the soil reported in percent. The Soil Hygrometer Humidity Detection Moisture Sensor uses capacitance to measure the water content of soil (by measuring the dielectric permittivity of the soil, which is a function of the water content)

Features: –

  • Soil Moisture Sensor Module
  • Fork shaped soil probe
  • 5-wire F/F interface cable, 8″ long

Soil Hygrometer Humidity Detection Moisture Sensor Specifications: –

  • 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

Soil Hygrometer Humidity Detection Moisture Sensor Pin Description: –

Pin Name Description
VCC
The Vcc pin powers the module, typically with +5V
GND Power Supply Ground
DO Digital Out Pin for Digital Output.
AO Analog Out Pin for Analog Output

Soil Hygrometer Humidity Detection Moisture Sensor Connections: –

  • VCC = 5V or 3.3V.  May be powered from a digital output pin on a MCU
  • GND = Ground, must be common with the MCU
  • D0 = Digital output of comparator circuit.  May be connected to MCU or directly to a 5V relay or similar device
  • A0 = Analog output usually connected to an analog input on a MCU
Probe & Module: –
  • The sensor contains a fork-shaped probe with two exposed conductors that goes into the soil or anywhere else where the water content is to be measured.
  • The sensor also contains an electronic module that connects the probe to the Arduino.
  • The module produces an output voltage according to the resistance of the probe and is made available at an Analog Output (AO) pin.
  • The same signal is fed to a LM393 High Precision Comparator to digitize it and is made available at an Digital Output (DO) pin. The module has a built-in potentiometer for sensitivity adjustment of the digital output (DO).
  • You can set a threshold by using a potentiometer; So that when the moisture level exceeds the threshold value, the module will output LOW otherwise HIGH.
Applications:-
  • Gardening
  • Irrigation Systems
  • Used in Controlled Environments
