Arduino-Ultrasonic

HC-SR04 Ultrasonic Sensor with Arduino

The HC-SR04 ultrasonic sensor is a distance measuring sensor which is used in many applications like obstacle avoidance robot, Car parking sensors, Sonar, Autonomous robots and many more. The distance measuring range is from 2cm to 4 meters. It is more precise than IR Sensors. Because its measuring capability does not get affected by light and also it can...

IR-Proximity

IR Proximity Sensor with Arduino

IR Proximity sensor is a simple Infrared Sensor which is used to detect obstacles. This is a multipurpose sensor and used in many robotic applications like Obstacle avoidance robot, Line Follower Robot, and any other obstacle detection projects. This is an Active Infrared sensor, it emits and detects its own IR rays. A passive infrared sensor only detects the...
