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. If you use STM32, connect the module as shown below. First resistive sensors for Arduino. Lesser the value means lesser the moisture in soil. https://lastminuteengineers.com/soil-moisture-sensor-arduino-tutorial Upload. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and sends a digital signal on the data pin. The capacitive and also the resistive soil moisture sensor works with supply voltages between 3.3V and 5V. Soil Moisture Sensor Before I use this sensor in some intermediate and advanced level projects, first I decided to make a very basic getting started tutorial to explain the basic connections and programming. Connect the "AC" Labeled pin on the moisture sensor to analog input 0 pin on the Arduino. This digital output (wet soil → L / dry soil → H) is routed to one I/O terminal (D2) of the Arduino microcontroller. The product includes an on-board voltage regulator which gives it an operating voltage range of 3.3 ~ 5.5V. This is the Interfacing Tutorial about Arduino and Capacitive Soil Moisture Sensor with the OLED Display project. If you're building a Smart Garden that waters plants automatically and give you the readings of the wet… Image : Description. It consists of two parts: The main Sensor and the Control Board. Features. To connect the soil moisture sensor FC-28 in the digital mode, we will connect the digital output of the sensor to the digital pin of the Arduino. Soil moisture sensors are designed in the form of two-pronged forks to easily sink into the soil. If you happen to have flowers you need to water often in your home, this can be the beginning of a cool adventure. This moisture sensor can read the amount of moisture present in the soil surrounding it. Part Number : SEN0114. Here we are going to use version 1.2 Capacitive Soil Moisture Sensor. Arduino | RaspberryPi | Robotics | Electronics | DIY | Unboxing | Review The sensor contains a set of pins on two sides.
