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. if the pH value decreases. 7) Diode – 1N4007 Response must be less that 100,000 characters. 5) NPN transistor – BC547 The code can be expanded to use an LCD display, indicators, alerting system, or any other devices. DIY Automatic plant watering system. The FC-28 module has both digital and analog outputs. For this self watering system you need an Arduino microcontroller, water pump, relais module and a capacitive soil moisture sensor. To avoid over or under-watering, the soil is never left completely dry or fully wet. The current moisture level can be read. With Arduino Yún settings and log files are stored on a SD card. The analog output AO of the FC-28 gives a direct analog value of sensor readings, because it is the value of voltage drop across the probe. It is an Arduino based automatic plant watering system that uses a soil moisture sensor. Here also the solenoid valve Opens and Closes respectively as the water level in the soil decreases and increases. This way, your plant is always looked after, even when you've forgotten about it or you're away. That is, value will be high when the soil is dry and the value decreases as it gets wet. It works with Arduino Nano. It’s time for a little feedback from the roots. The sensor value will be compared with this threshold value by the LM393 comparator. Smart Watering System. Mechatrofice © 2020. 1) Arduino board – For Arduino based circuit Water pump gets automatically off when system finds enough moisture in the soil. That is if the soil is less moisture then the voltage across the probe becomes high and that switches digital output to high state.

Updated October 27, 2020. The circuit diagram for automatic plant watering system over network using ESP8266 is given below. Lower voltage between the legs mean less moisture in the soil, which will turn on the water pump by using a conventional relay. Fortunately, a Baseline soil moisture sensor is much more than a reporting device. Thus the DO of the sensor switch to a HIGH state and the solenoid valve opens. Things used in this project .

This project is about a moisture-sensing automatic plant watering system using Arduino UNO. For an automatic plant watering system, we can adopt various techniques such as time-based water pump controlling or by sensing various parameters of the soil and surroundings, etc. Automatic irrigation is a concept of controlled watering of plants without any manual operations so as to maintain a water level ideal for its cultivation. The tube is used to take water from the pump's outlet onto the plant. An NPN transistor is used as a switch to control the solenoid valve. 2) FC-28 sensor The output LED is just inverse to the digital output if DO is High then the LED turns OFF. The SIG out is the analog output that is connected to the analog input pin of the Arduino. Here in this project, the water control is done by monitoring the instantaneous level of water content or moisture present in the soil. Gikfun Soil Moisture Sensor Kit Automatic Watering System Manager with Mini Water Pump for Arduino DIY Kit EK1915. You can use the circuit given in “standalone Fc-28 Soil moisture sensor without a microcontroller”. When the water level is low, the sensor value rises above the threshold value as the soil resistance increases. You may have to refill your container every once in a while. The relay and soil moisture sensor use the same pass through 5V DC from the Arduino board. There's a problem loading this menu right now. Your email address will not be published. The value set by adjusting the potentiometer in the FC-28 module. After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. 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. Using the digital output, the FC – 28 sensors can be used as a standalone system to directly drive devices without any microcontrollers. The only sensor I can find has a digital output, will i be able to use it, and if yes what would I have to change? In This Plant Watering System, Soil Moisture Sensor checks the moisture level in the soil and if moisture level is low then Arduino switches On a water pump to provide water to the plant. The Arduino continuously check the sensor reading and check it with the condition function in the code. The pump delivers water from your container into your plant. Gikfun Soil Moisture Sensor Kit Automatic Watering System Manager with Mini Water Pump for Arduino Garden DIY Kit EK1915U 3.0 out of 5 stars 7 £16.98 £ 16 . It will not only automatically irrigate the water based on the moisture level in the soil but also send the Data to ThingSpeak Server to keep track of the land condition. This project is about a moisture-sensing automatic plant watering system using 8051 microcontroller. Hence, the moisture level can be estimated with respect to the electrical conductivity or resistance of the soil.

I'm a Belgian multimedia student and for the course physical computing and digital making, we had to experiment at home with a project of our choice. automatic water irrigation system .....Code link click on Website :-http://techwarriorsinfo.blogspot.com/2018/09/blog-post.html 88. A controller 20 controls the infrared transmitter 16, the infrared receiver 18, and a sprinkler valve 23. Sensor 2 and sensor 3 are also above moisture sensor senses the amount of moisture principle. I'm a huge plant lover, so … 3) Solenoid Valve Technical specifications Supply voltage: 3.3v or 5V Working current: less than 20mA Output voltage: 0-2.3v [2.3v is the voltage value completely immersed in water], 5V power supply, the higher the humidity, the higher the output voltage. Here an FC-28 moisture sensor is using for the measurement of the moisture level in the soil. The sensor is a pair of test probes which are placed or inserted into the soil. 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. I wet my plants! The output LED lights as the water level reaches above the preset level. The Wi-Fi module operates on 3.5V DC provided by the Arduino board’s 3.5V pin. Here code is to use the analog output of the module, so the Arduino can read instantaneous readings from the sensor. A controller 20 controls the infrared transmitter 16, the infrared receiver 18, and a sprinkler valve 23. The author’s prototype is shown in … It sends 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. When the sensor value is above the set threshold value the digital output DO will switch to a HIGH state (+5V). An outlet supplies power to the pump and the relay module(JQC-3FF-S-Z) regulates the pump. A piezo speaker will let us know that watering is complete.
