Why this Project?
As Modern houses are gradually shifting from conventional switches to centralized control systems, our idea mainly deals with the problem of farmers through the smart switch technology which is based on IoT and makes life easy, efficient, and better and enhances their standard of living so that they do not find difficulties in their daily day-to-day task thus making their daily routine efficient and productive. Involving remote-controlled switches.
Presently, conventional switches located in different parts of the farms make it difficult for the user to go near them to operate. Smart switches provide the most modern solution for smartphones. Our system majorly deals with when there is an assessment of the major agriculture and industrial works manually. this legacy of manual work sometimes constrains the worker to analyze the work by going in the field every time. Due to the uncertainty of power faults, the worker exhausts his energy by traveling a tractorable distance for the farm.
Our system deals with the eradication of this problem as our system consists of IoT-based technology powered by solar panels. this modern means of technology help in accessing the problem by sitting in one place. By means of this adaptive technology users can easily access the working condition and operative modes of machinery that are used in their farms by sitting at only one place instead of traveling long distances to the field in unfavorable conditions. The main objective is to provide facilities to the farmers.

Farm Automation System Circuit
Working
Our smart switch system is made using Arduino UNO, GSM MODULE, and a smartphone. The aim of this system is to control different agricultural machinery using a smartphone.
When the power is turned on, the connection LED on the GSM MODULE starts blinking. We need to start the app (made through MIT APP INVENTER) on our smartphone and get connected to the GSM MODULE. If the pairing is successful, the LED becomes stable.
Now, in the app, we need to set different keys for different loads and their corresponding value that must be transmitted when that key is pressed. Then we are ready to control the loads.
When a key is pressed in the smartphone, the GSM MODULE receives the corresponding data and the intern transmits that data to Arduino. If we send “Motor on”, then the data received by the GSM MODULE. This data is transmitted to Arduino then compares the received data with the data written in the sketch and accordingly turns on the ‘Motor’.
A similar action can be applied to other keys and loads. Using this type of connection, we can control turn on or off different electrical machines using our Smartphones. also, we get the acknowledgment on our phones.
The GSM MODULE has 4 – pins: VCC, TX, RX, and GND. VCC and GND pins are connected to 5V and ground to Arduino UNO. The GSM MODULE works on 12V. The TX and RX pins of the GSM MODULE must be connected to the RX and TX pins of the Arduino.
When connecting RX to TX pins of Arduino (or any microcontroller as a matter of fact), we need to be careful as the pin can tolerate only 5V. But the voltage from the TX pin or Arduino will be 5V. So, a voltage divider network consisting of 10K and 20K resistors is used to reduce the voltage to 5V approximately.
