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.
