Raspberry Pi based Solar Street Light

This project is intended for auto intensity controlling of solar LED street lights using solar power from PV cells interfaced to a Raspberry Pi. Day by day solar power awareness is increasing. The awareness of solar power is increasing, and a lot of people and establishments are choosing solar power. PV cells are used for charging batteries by changing the daylight into electricity. A charge controller circuit is employed to regulate the charging.

The street light intensity is needed to be kept high throughout peak hours. Because the traffic on the roads decreases gradually in late nights, the intensity can be decreased gradually till morning to conserve energy. Therefore, automatically the solar LED street lights to turn ON at the dusk and then turns OFF at the dawn and every day this process repeats daily

HID lamps are used in the urban street lights and these are based on the principle of gas discharge. Therefore, the light intensity isn’t controllable by any voltage reduction method because the discharge path is broken. LEDs are the longer term of lighting, attributed to their low energy consumption and long life. These lights are quick replacement standard lights world wide. White LEDs will replace the HID lamps whenever intensity control is feasible by PWM( Pulse Width Modulation

The intensity of light helps in saving energy throughout late nights, whereas traffic density on the streets is low. A Raspberry Pi board is engaged to supply totally different intensities at the various times of night victimization PWM technique, for energy-conserving for a star-based system, employing a charge controller for battery charging, overload, and deep discharge protection.

Raspberry Pi based Programmable Sequential Switching

This project is used to operate industrial loads with a user PLC for consecutive operation with the Raspberry Pi board. This operation is usually used for the respective nature of work.

PLCs is employed in industrial applications for easy operations like serial switching of loads. The proposed system uses a Raspberry Pi and the development of this application needs the formation of the program via i/p key buttons. In industries, there are several tasks are administered which requires some recurrent operation in various orders

For instance, particular loads need to be turned ON/OFF at particular time intervals. So as to attain this, the Raspberry Pi is programmed in such a way that the different loads can be operated in 3 modes such as the set, auto & manual mode. In the set mode, through timers, the machinery works based on i/p time arranged by the user whenever as in auto mode it works on default time settings and eventually in the manual mode, it functions whereas individual key buttons are pushed depending on the user requirement. All the status and modes are displayed on a TV or PC.

Thus, tasks performed by costly PLCs will currently be achieved by employing a Raspberry Pi board creating the device price effective. In the future, this project is often increased by interfacing it with a GSM device wherever by sending an SMS to the system we will choose the mode and timing remotely.

Raspberry Pi based Motor Speed Control

The proposed system uses a Raspberry Pi to control the speed of a DC motor. The speed of the motor is directly proportional to the voltage applied across its terminals. Therefore, if the voltage across the motor terminals is different, then the speed of the motor can also be different.

In this project, a keyboard is interfaced to the board and it works as an input. Here, the keyboard is used to control the speed of the motor. PWM is produced at the o/p by the board according to the program. Depending on the duty cycle, the average current flowing or the average voltage given through the motor will change so, the motor speed will change. The pulse width modulation signals can be received by interfacing a motor driver to the board. A motor driver IC is interfaced to the board for receiving PWM signals and sending preferred o/p for speed control of a small DC motor.

Raspberry Pi based Auto Intensity Control

This project uses LEDs in the place of HID lamps in the street lights. A Raspberry Pi is used to control the light intensity by developing PWM signals which drive a MOSFET to turn the LEDs according to the required operation.

A bunch of LEDs is used to make a street light. The Raspberry Pi board comprises programmable instructions, that controls the light intensity based on the pulse width modulation signals produced. The light intensity can be kept high throughout peak hours. Hen the traffic on the roads decreases slowly, then light intensity also decreases till morning. Finally, it shutdowns at 6 am and again continues at 6 pm in the evening.

Wifi Based Smart Notice Board using Raspberry Pi

Wireless communication has helped in the development of technology in many ways. With the development of wireless communication technology, communication systems have seen a tremendous change in there design, size, accuracy and reliability. Wifi is one of the modes of wireless digital communication.

In this project, a Digital smart notice board is designed which uses wifi technology for communication. Here the authorized user can send the message to the notice board directly. At the notice board, this message is displayed. A server is used for sending notices. At the receiver end, the wifi module is embedded with Raspberry Pi, to which LCD display is attached. These texts can be altered or deleted by the user. Authorized students can access their academic details using voice commands.

A Raspberry Pi controlled Cloud-based Air and Sound Pollution Monitoring System with Temperature and Humidity Sensing

Pollution is the growing cause of concern for our environment. With the rise in pollution levels, greenhouse effect and global warming are increasing at the dangerous speed. Air pollution has become the leading cause of many lung diseases.
