The relay and soil moisture sensor use the same pass through 5V DC from the Arduino board. In the here circuit a solenoid valve is using for water control. If the only pin you have is a digital output, then you can adjust the threshold by varying the potentiometer in the sensor. You may have to refill your container every once in a while. Actually they wet themselves when they are thirsty, how convenient is that?! The Smart irrigation System has wide scope to automate the complete irrigation system. Using Arduino, additional features can be added to the system. The value set by adjusting the potentiometer in the FC-28 module. The moisture level sensor works with the basic principle of electrical conductivity of water that is the resistance value of the wet soil is lesser than the dry soil. 98 C. Working The system works on the principle of sensing and The sensor module board mainly has an LM393 comparator, potentiometer, indicator LED lights – Power and Digital Output Indicator LEDs; commonly red for power indication and blue for digital output. Fortunately, a Baseline soil moisture sensor is much more than a reporting device. 3.3 out of 5 stars 25. It is an Arduino based automatic plant watering system that uses a soil moisture sensor. 88. In Arduino based system both digital and analog outputs of the sensor can be used as an input signal. if the pH value decreases. The threshold water level can be adjusted by changing the value of the variable “threshold” in the code. DIY Plant Moisture Sensor With Automatic Watering System: Hi everyone,Today I'm going to share my first Arduino project with you. The soil moisture sensor is the most amazing sensor used to measure the quantity of water present in the soil and defines the moisture level of the soil as the output. Thus the DO of the sensor switch to a HIGH state and the solenoid valve opens. The pump and solenoid valves are provided with a separate supply by a single 12V, 4A DC connection. If the soil moisture sensor is not available, the following circuit can be used as an alternative. Circuit Diagram: Here we just replaced the arduino with ESP8266 nodeMCU, you can use wemos D1 or ESP32 in place of nodeMCU. $14.88 $ 14. When the soil has reached the desired moisture level, your automatic irrigation system will not be started, or an ongoing irrigation will be interrupted – in this way you can save water and still have beautiful and healthy plants. The solenoid valve requires an external power supply. The Paris-based company also revealed an update to its Flower Power sensor, which can be stuck in the ground near a plant to monitor temperature, sunlight, soil moisture and fertilizer levels; the new version allows almost any screw-top water bottle to be attached as a reservoir for automatic watering. Automatic irrigation of plants on vacation. The sensor used in the project is shown below. We connected the soil moisture sensor to the 5v power supply because the 3v supply from nodemcu is not sufficient. As plant get sufficient water and soil get wet then sensor senses enough moisture in soil. The Arduino continuously check the sensor reading and check it with the condition function in the code. Source Code: Using the digital output, the FC – 28 sensors can be used as a standalone system to directly drive devices without any microcontrollers. 7) Diode – 1N4007 Here also the solenoid valve Opens and Closes respectively as the water level in the soil decreases and increases. An assembled circuit of the automatic irrigation system; the Arduino sketch runs with a standalone Atmega 328p microcontroller. uses sensor that determines soil moisture (by soil moisture sensor), water level indicator also its pumping system that aims to deliver the needed water based on the assigned soil moisture value. The current moisture level can be read. Here an FC-28 moisture sensor is using for the measurement of the moisture level in the soil. It consists of two prongs, which must be inserted in the soil, an LM358, which acts as a comparator and a pot to change the sensitivity of the sensor. As its name suggests, this sensor tracks the moisture content in the soil and, via Arduino, a pump is controlled that provides water to the plants. The automatic moisture sensing and watering system 12 includes a moisture sensor 14, which generally includes an infrared transmitter 16 and an infrared receiver 18. With the new SMRT-Y Soil Moisture Sensor Kit from Rain Bird, an irrigation controller is directly linked to the absolute moisture requirements of a site’s vegetation. This project is about a moisture-sensing automatic plant watering system using Arduino UNO. The sensor is a pair of test probes which are placed or inserted into the soil. You should know that the most important sensor is the soil moisture sensor, which is an analog sensor. Smart Watering System. Analog input reads the SIG output and converts it to corresponding decimal values. A controller 20 controls the infrared transmitter 16, the infrared receiver 18, and a sprinkler valve 23. If soil will get dry then sensor senses low moisture level and automatically switches on the water pump to supply water to the plant. The automatic moisture sensing and watering system 12 includes a moisture sensor 14, which generally includes an infrared transmitter 16 and an infrared receiver 18. The Micro:bit uses a moisture sensor to monitor the moisture level in the plant's soil and then switches on a small pump to water the plant if the soil gets too dry.
