“Siren for agriculture using solar” project is used for the security system. Solar converts light energy into electrical energy. The main disadvantage of the solar panel is, it is weather dependent in which it cannot produce electricity during the storm, or on a cloudy day or at night. So, that we are using a main supply when the absence of solar panel. Solar panel is used to store the energy whole day and night. It is used to charge the battery in the day times and it helps in low power consumption. Now a days it is necessary to save the power. As non-renewable source decreases, usage of solar panel will be increased. Energy is very important in today’s world. It has become a part of our life and we cannot think a day without electricity. This project has the feature of RFID authorized entry into the field. Also there will be an alarm sounding if someone tries three times to enter with wrong card. The buzzer will sound automatically after each 15 minutes to alarm the animals getting into the field. There is a mobile application interfaced with this. This mobile application will show the status of the solar panel, option to switch between solar panel and main supply and also if there will be any trial of unauthorized entry into the field.
The block diagram of Siren for agriculture using solar consist of following elements:
- RFID Reader and tag
- NodeMCU ESP8266
- Siren Module
- Mobile Application
The main purpose of this circuit is to build a system that allows authorized person automatically to the agricultural field, restricts unauthorized person from entering, sounds the siren on unauthorized entry, sounds it after each 15 minutes automatically to warn the animals nearby and show all of these status in a mobile application. The agriculture land will have a door installed there. This door will have a RFID reader. Some RFID cards will be authorized and will be given to the people whom we are permitting to enter inside. Now when that person wants to enter, he will swipe his card at the door, on the RFID reader installed. The RFID reader will sound the buzzer indicating towards the RFID tag swipe. Also it will send the signal to microcontroller through Tx pin. When microcontroller gets this input, it sends signal to the servo motor connected at D2 pin. Servo motor rotates to open the door and when the person enters, it closes the door by rotating in reverse. In another case, if someone tries to enter the field by swiping an unauthorized card three times, the microcontroller gets input through RFID reader EM-18 Tx pin. In this case, it sends signal to the siren through op-amps (to amplify the signal strength) and the siren starts buzzing. The siren is also gets signal from microcontroller after each 15 minutes and keeps sounding at each 15 minutes so that any animal nearby keeps warned and doesn’t try to enter inside. There is a mobile application build for this. NodeMCU ESP8266 is a Wi-Fi module along with microchip. It generates a Wi-Fi hotspot to which the mobile having application will get connected. This mobile application will have an option to switch between solar panel and mains for power supply. Also it will have option to control the volume of the siren. It also shows if there is any unauthorized entry attempt made.
Target of this project is used to protect the agricultural field from the animals and from the unknown person.
