9) And then whole information will show on the Android app. User can easily control the motor manually by using Android app.

� The project’s aim is to detect the dryness in soil using moisture sensor and provide water to the plants appropriately. This project helps to maintain the plants quite easily.

� As there is no unnecessary usage of water, a lot of water is saved from being wasted.

� We are using soil moisture sensor which provides us the moisture content through the blynk app and accordingly we get notification when the pump should be turned on/off. This saves a lot of time for us. This also gives much needed rest to us, as we don’t have to go water the plant manually.

� The main objective of the project is to use the internet of things(iot) to achieve the following goals:

� No need for the customer to manually keep on checking the plants health.

� Power consumption of a wireless sensor network should be less so that it can be used for a long period of time.

� Precision in providing the environmental condition of the plant.

� Automatically water the plants when the owner is not present.

� To know the health condition of the plant.

OBJECTIVES

The main objective of this project is using the hardware and software together. This project is used to implements the technology with nature.

It is nontoxic.

It is like a second hand uses in gradient to protect the plants, IT automatically work and send all information on the cloud through android app which notify about plants condition, so doctor team can reach on time, and we can save plant, this will be more valuable for earth. This device uses Wi-Fi Arduino system i.e., calledNodeMCU.

SCOPE OF WORK

The performance of the system can be further improved in terms of the operating speed, memory capacity, and instruction cycle period of the microcontroller by using other high-end controllers. The number of channels can be increased to

interface a greater number of sensors which is possible by using advanced versions of controllers.

The system can be modified with the use of a data logger and a graphical LCD panel showing the measured sensor data over a period.

A speaking voice alarm could be used.

The device can be made to perform better by providing the power supply with the help of renewable source.

Time bound administration of fertilizers, insecticides and pesticides can be introduced.

CONCLUSION

The proposed system can reduce the efforts of daily watering of plants. It also conserves water for irrigation by locating the sensor at the right position above the soil level. The plants can still sustain at low moisture levels when the temperature is moderate. The system is used to switch on/off the water pump according to the sensor readings there by automating the process of irrigation, which is one of the time-consuming activities. The system uses information from the sensors to irrigate soil which helps to prevent over irrigation (water wastage). Users can monitor the process online through a website. From this system it can be concluded that there can be considerable development in farming with the use of the Internet of Things.
