![]() ![]() The square wave generated is then fed to the sensor like a capacitor. There is a fixed frequency oscillator that is built with a 555 Timer IC. The Hardware Schematic for Capacitive Soil Moisture Sensor is given below. Size: 99x16mm/3.9×0.63″ Capacitive Soil Moisture Sensor Schematic The advantage of Capacitive Soil Moisture Sensor is that they are made of a corrosion-resistant material giving it a long service life.Ħ. The capacitance is converted into voltage level basically from 1.2V to 3.0V maximum. ![]() This is an analog capacitive soil moisture sensor which measures soil moisture levels by capacitive sensing, i.e capacitance is varied on the basis of water content present in the soil. You can purchase all the components from Amazon.Ĭapacitive Soil Moisture Sensor v1.2 Overview The following are the components that you need for making this project. It is perfect for low-voltage microcontroller with both 3.3V and 5V power supply. This module includes an onboard voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. Insert it into the soil around your plants and monitor the real-time soil moisture data. It is made of corrosion-resistant material which gives it excellent service life. This soil moisture sensor measures soil moisture levels by capacitive sensing rather than resistive sensing like other sensors on the market. This sensor measures the volumetric content of water inside the soil and gives us the moisture level as output. Here we will use Capacitive Soil Moisture Sensor v1.2. This can be measured using a soil moisture sensor either resistive or capacitive. Soil moisture is basically the amount/content of water present in the soil.
