1. So to get rid of this problem, I came up with. A relay has three types of possible connections COM (common mode), NC (normally closed switch) and NO (normally open connection). On the left side there are two 4 pins and one 2 pins screw terminals; the two 4 pins are used to connect the display and the RTC, whereas the 2 pins screw terminal to connect the PCB to Arduino pins A4 (SDA) and A5 (SCL) for I2c comunication. Among the lots of comments on your articles. Arduino Plant Watering System: This Instructable will explain how to make a plant watering system powered by Arduino. In NO mode relay acts as a switch. is electromechanically or electrically operated switch which is operated by a relatively small amount of electric current which can control the switching activity of the large electric current operating devices. Each of the components is specified with a link to where they can be purchased online. On the other side to operate water pump I used relay module. I have also made an advance level project "Smart Plant Watering System" using a soil moisture sensor. Similarly, connect echo pin to the digital pin 11. Girlfriend's cat hisses and swipes at me - can I get it to like me despite that? Being fairly new to the world of Arduino I seek your guidance on a simple project I would like to bring to life: running a 12V pump to water a plant. Arduino Controlled Pump for Draining Water: The idea of this project came out when I bought a condensing gas boiler for my apartment. Interface mini water pump with relay and power. This system water to the plant only at daytime whenever the soil is dry. Arduino Uno is a kind of small computer that has an eight-bit microcontroller, programmable hardware, USB programmable interface, input-output pins along with excellent processing capability to connect the computer to the physical world. 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. I used a 12-volt submersible pump for this project which has 18-watt motor that can lift water up to 1.7 meters. The problem is, I cant wrap my head around how to connect it to a power supply, can I use my old Nokias phone charger as power supply? LDR are light sensitive devices which are used to identify the presence and absence of the light intensity. Two sensors are connected to A6 and A7 pins of arduino nano, through a transistor BC547. I don't have any drain close by for the condensed water the boiler produces. CIRCUIT CONNECTION Connect trigger pin on the Sonar sensor to the Arduino digital pin 12. Hands-on project on how to make The smart Irrigation prototype using Arduino Water pump and soil moisture sensor. Cryptic Family Reunion: Watching Your Belt (Fan-Made). Base pin of transistor is connected to the D7 pin of arduino through a 10K Ohm resistor. On the bottom there are two 4 pins screw terminals; the one on the left, near diode D1, to connect pump 1 (Arduino pin D11). Thanks for sharing.Sindh Irrigated Agriculture Progress, I'm new to using these components but want to try this one as a challenge. Connect Arduino to PC via USB cable; Open Arduino IDE, select the right board and port; Copy the above code and open with Arduino IDE; Click Upload button on Arduino IDE to upload code to Arduino; See the pump's state; Code Explanation. Interested in water? If the soil is dry than soil moisture sensor senses high moisture level of soil and if the soil is wet than soil moisture sensor senses low moisture level of the soil. This Arduino Pump Tutorial shows an example of how to use a float switch, Powertail, and pump to create a sump pump system. Just in case you do not know what is pressure controller, it is a device that usually sits on top of the pump and controls it depending on the pressure in pipes. What type of targets are valid for Scorching Ray? site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. Upload your code, then disconnect the USB cable. Been trying for hours and struggling could you help me with code at all? This code also turns on the built-in LED during watering. I have been trying to get the water pump to read the moisture data and if it reads lower that 60 to turn on the pump for 10 seconds and then turn the pump off until it reads the moisture again to see if it needs more water. Therefore, if it exposed to dark light than its resistance value is high but when it identifies enough brightness in light than its resistance value decreases up to a few ohms. The program is written in such a manner that as light dependent resistor senses value less than or equal to the threshold value than it means there is dark and whatever is the value of soil moisture sensor pump should be switched off. This comment has been removed by a blog administrator. 5V relay module (quantity: 1 no.) Find these and other hardware projects on Arduino Project Hub. Common pin of the relay is connected to positive terminal of the Submersible water pump. With web interface we can control water pump and soil moisture remotely. Smart Plant Watering System Using ARDUINO UNO, How to operate soil moisture sensor with Arduino, how to display numbers on LCD by Arduino uno, How to operate buzzer using a push button with Arduino Uno, How to use temperature sensor with Arduino Uno. Usually, the ideal time to water the plants depends on the climate condition and the regions where plants are available.
