Soil Moisture sensor estimates the moisture content in the soil. This sensor consists of two probes through which the current passes that estimates the resistance and indeed estimates the moisture content in the soil.In this project,the percentage moisture content was read from the sensor.The Output acquired by coding and making connections with NodeMCU is given below.
DHT Sensor:
DHT sensor estimates temperature and humidity of the sensor.It consists of a humidity sensing component, a NTC temperature sensor and an IC on the back side of the sensor. For measuring humidity they use the humidity sensing component which has two electrodes with moisture holding substrate between them.The parameters temperature and humidity was sensed and the data was dumped to NodeMCU.The output data seen on the serial monitor of arduino IDE is given below
Rain Sensor:
Rain sensor senses if it is raining or not.Rain sensors are based on the principle of total internal reflection.Data was dumped into NodeMCU.The output was observed on the serial monitor.
Relay:
Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit.
Step 2 : Combing all the components
Data gathered from sensors and output accessed individually, is now collaborated with all sensors with the inclusion of relay and motor. Relay acts as a switch giving access to other sensors when ON.This builds the basic prototype manually handled.
Step 3 : Machine learning for Weather Prediction
Collaborating with the team of DataScience working on Rainfall prediction,watering the plant is dependent on it.Initially, the data of temperature and humidity acquired from the DHT sensor is provided to the team for rainfall prediction.The idea is plant is watered only in the absence of rainfall.
Step 4 : Monitoring the plant on portable device
To check the wellbeing of the plant,all the information regarding the plant is accessed on phones via apps.It follows through a procedure of establishing the NodeMCU having access to the Internet.
Step 5 : Image Processing
For establishing the advanced model of this project,Raspberry pi comes into the picture which allows image processing for the check of weeds and pests on the plant.
Step 6 : Water Storage
The water provided to the plant in the absence of rain has to be stored.To avoid large consumption of land for the storage of water,underground water tankers is the solution for plant getting water access.
Step 7: Inclusion of soils considering the soil moisture required for different plants.
Step 8:The power supply on a large scale can be supplied by lithium ion batteries near the DC power supply.
Step 9 : This is the training stage for checking if the plant works according to the plans of project.
CONCLUSION:
All the versions implemented above creates a self sufficient plant.Firstly,data is collected .Secondly,weather is estimated.And then,plant is watered depending on weather conditions.Monitoring is done on portable devices.This project encourages afforestation in response to reduce the global temperatue.
