The Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The moisture sensor consists of two probes that are used to detect the moisture of the soil. Volumetric sensors measure the actual volume of water in the soil. The comparator IC will compare the threshold voltage set using the preset (pin2) and the sensor pin (pin3). The I2C Soil Moisture Sensor is a "sensor mode only" version of the plant watering alarm Chirp. Pin … This is an easy to use digital soil moisture sensor. Victoria Lee Blackstone is a horticulturist and a professional writer who has authored research-based scientific/technical papers, horticultural articles, and magazine and newspaper articles. Parallel-Plate Capacitor As the name suggests, capacitive soil moisture sensors use the working principle of a capacitor to approximate the moisture content in soil. Connect the Analog/Digital Output pin of the module to the Analog/Digital pin of Microcontroller. Simply insert this rugged sensor … The more soil moisture available in the soil, the lower the resistance and the corresponding number on the reader. As the moisture inside the tube reaches equilibrium with the soil moisture outside the tube, the moisture tension registers on the gauge. The soil moisture sensor is pretty straight forward to use. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil. It measures the volumetric content of water inside the soil and gives us the moisture level as output. After studying botany and microbiology at Clemson University, Blackstone was hired as a University of Georgia Master Gardener Coordinator. Tensiometer probes are water-filled tubes that you insert into the soil to the depth of plant roots. The moisture sensor probes are coated with immersion gold that protects Nickel from oxidation. The soil moisture sensor consists of two probes which are used to measure the volumetric content of water. A porous block, typically made of gypsum, is placed on top of the soil and must maintain firm contact with it. When soil is dry, a plant must use greater suction to extract the available water from the soil. Pin 2 of LM393 is connected to Preset (10KΩ Pot) while pin 3 is connected to Moisture sensor pin.
