The board has only one  relay driven by TTL circuit . The board works on 5V but the input signal can come directly from Raspberry Pi and Arduino  output working at 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by individual LEDs.

The ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial and communication systems. The devise package allows for easy implementation by the customer. The typical application includes motor control, load detection management, switch mode power supplies and over current fault protection. The device is not intended for automotive applications.

Driver fatigue is a significant factor in a large number of vehicle accidents. The development of technologies for detecting or preventing drowsiness at the wheel is a major challenge in the field of accident avoidance systems. Because of the hazard that drowsiness presents on the road, methods need to be developed for counteracting its affects. The aim of this project is to develop a prototype drowsiness detection system. The focus will be placed on designing a system that will accurately monitor the head movements of a driver in real-time. By monitoring the head movements, it is believed that the symptoms of driver fatigue can be detected early enough to avoid a car accident.

A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the ways to do this is by comparing selected facial features from the image and a facial database. It is typically used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems.

The regulated power supply accepts unregulated intputs from 12V to 15V AC or DC and gives regulated output of 3.3V  5V and 12V suitable for  projects which needs precise voltage to work. The input can come from step down transformer. Since board has diode  bridge input polarity does not matter.All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.

secure low cost Automatic Meter Reading (AMR) system that calculates and transmits the total electrical energy consumption to main server using General Packet Radio Service (GPRS) technology provided by GSM networks. The proposed AMR system consists of three main parts: Accurate digital meter, a transmission facility and the billing server. To make affordable AMR system a low cost off-the-shelf materials are used.
