Eye Blink Sensor Project Kit
The Eye-Blink sensor works by illuminating the eye and eyelid area with infrared light, then monitoring the changes in the reflected light using a phototransistor and differentiator circuit.
This includes Arduino Nano, Eye Blink sensor, Buzzer, Battery, Clip Connector, and Switch.
Eye Blink sensor senses the eyeblink using infrared. The Variation Across the eye will vary as per eye blink. If the eye is closed the output is high otherwise the output is low.
Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) or ATmega168 (Arduino Nano 2.x). It has more or less the same functionality as the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one.
A Standard Active Buzzer Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. This PCB Mounted Active Buzzer Module can produce a range of sound tones depending on the input frequency, i.e it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.
This is a general 9v Battery for all your project and application needs.
A clip Connector is used to connect a 9V battery to the application. This snap power cable to DC 9V clip male line battery adapter for mostly used to power Arduino boards.
Rocker switch is Rocker Switch SPST ON/OFF Microswitch.

Arduino Sensors Combo of 5 Kit
This is a basic combo for Arduino and Robotics starter. This set can be used for obstacle sensing cars, Ultrasonic radars, school projects i.e. automatic barrier, automatic light, etc. This combo includes an ultrasonic sensor, motion sensor, IR obstacle sensor, LDR, SG90 Servo motor.
HC-SR04-Ultrasonic Distance Measuring Sensor is a very popular sensor that is found in many applications where it requires measuring distance and detect objects.
HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
IR sensor module is adaptable to the environment, with a working voltage of 3.3 V to 5 V. It has a pair of infrared transmitting and receiving tubes when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving by the tube.
Photoresistor also is known as LDR(Light Dependent Resistor) as the names imply, changes the resistance with the variation in the amount of light. This particular photoresistor has a resistance of 5-10k Ohm in light and about 500k Ohm resistance in the dark.
Micro Servo 9G is lightweight, high-quality, and lightning-fast. The servo is designed to work with almost all radio control systems. It is with excellent performance that brings you to another horizon of flight. The SG90 mini servo with accessories is perfect for R/C helicopter, plane, car, boat, and truck use.
