It is used in agriculture applications, irrigation and gardening systems, etc. Share Image of Project made by you after watching my Tutorial. The sensor is composed of a two parallel aluminum plates (as in a capacitor): The output of this circuit is connected to analog arduino pin A0. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and sends a digital signal on the data pin. I was researching on this forum about the capacitive soil sensor v1.2. Therefore you can use the Arduino (5V operating voltage) and also the ESP (3.3V operating voltage) based microcontroller to measure the soil moisture. Soil Moisture Sensor Library in Proteus.Soil Moisture Sensor Library For Proteus 7 and 8.you can download arduino library below link Features. We opted to use the v1.2 capacitive soil moisture sensor in this guide because it’s cheap and easily available on the internet. Here we are going to use version 1.2 Capacitive Soil Moisture Sensor. The function of this module is simple. The main component of the project (apart from the Arduino UNO) is the Soil Moisture Sensor. Soil Moisture Sensor With Arduino. Price range: around 0.5$ on Aliexpress.com. Soil moisture can be measured using a soil moisture sensor either resistive or capacitive. 49 ($0.94/100 Items) Soil Moisture Sensor For those who may find it difficult to follow the schematics, the pin connections for the LCD is also described below.
