IoT Based Smart Agriculture + Automatic Irrigation System with ESP8266

hello everyone this is mrada from how to electronics in this video we will make iot best smart agriculture with automatic irrigation system here we will use capacitive soil moisture sensor to measure moisture content present in the soil we will also use dht11 humidity temperature sensor to measure the air temperature and humidity using a 5 volt power relay we will control the water pump whenever the low quantity of moisture is detected in the soil the motor automatically turns on and hence the irrigation is done automatically once the swell becomes wet the motor turns off all this happening can be monitored remotely through sync's pick server online from any part of the world this project also requires a custom pcb so i used easy eda to design the custom pcb first i designed the schematic then i converted the schematic into a pcb so you can see the 3d view of the pcb front side as well as the back side then i generated the gerber file now you can visit next pcb official website and order the pcv at very cheap price all you need is upload the gerber file then view your pcb in carver viewer then select the details like pcb quantity specific color and thickness then select the country of shipment and then place an order so that's all currently the next pcb is giving a biggest discount with lottery draw and free order link is given in the description there is 20 percent off for pcb orders and hundred percent lottery job winning rate you can get free pc order free smt order thirty two hundred dollar ten dollars to five dollar coupon without limit click here for that go through these easy rules for getting participated in this lottery draw apart from this 20 of pcv orders and 15 of smt orders you can go for pcb prototype mass production multi-layer pcv board pcb assembly [Music] [Music] for this project we need node mcu board a capacitive soil moisture sensor a 5 volt relay module 0.96 inch olate display dhd11 sensor break board and a 5 volt dc pump motor the motor is used for drawing water from inlet and throwing water through the outlet a pipe can be connected to it so now here is the schematic of the project i used freezing to make and schematic which is beautifully designed just place on connect the component it's super easy so the final schematic is ready soil moisture sensor is connected to a net of node mcu and dht11 to d4 pin the motor is connected to relay the relay is controlled using d5 pin of node mcu the oled display is connected to 12c pin of nodemcu so here is the final assembly on the breadboard i highly recommend you to do this project in a pcb board the breadboard connection might give you some issues for a demonstration purpose i use the breadboard for assembling the circuit so i have a small tube with soil and a grass growing in and a tube with water the tube is a water source from where the motor can draw water whenever it's necessary this is a soil moisture sensor dht11 sensor relay module oled display node mcu board and a water pump this water pump need to be fully submerged in water the outlet pipe is kept in a field for irrigation similarly soil moisture sensor is dipped in soil as soon as the device is powered the oled will start displaying the soil humidity air humidity and also air temperature is showing the real time data as you can see here when the soil moisture content is reduced the water pumps turns on and irrigate the field until the required moisture is achieved you can check its full working hair in this video now what i want is i want to monitor the data online on internet from any part of the world so create an account on things big server as i have already created an account as a simply sign in after that create a new channel write the name of the channel also fill the four different fields as soil moisture humidity temperature and motor status and save the channel then go to the api keys and copy the right api key this api key is required in code and you need to pass it here now let's see the code part we need few libraries for that all the libraries link is given below the code is pretty simple and easy to understand but you need to make some changes in few parameters for example change the api key change the wifi access id and password here we are uploading the data to things pixelver this line is used for retrieving the value of air temperature and humidity similarly we are reading the soil moisture data from soil moisture sensor and converting it into percentage using a map function then we'll display the values on oled screen using sum inbuilt library function these lines are for turning on and off the motor when a particular result is achieved i have defined 30 as a threshold value you can use yours depending upon the application now using the post string function we are uploading the four datas to think spec server you can see from field 1 to field 4 as soil moisture humidity temperature and release status you need to upload this code now to node mcu board so select the right board and then a right port and hit the upload button so once the code is uploaded you are done you can go to the private view of things pick server here you can see the status of soil moisture humidity and temperature as well as relay status so that's all from today see you all in the next video thank you for watching
