HC-SR04 Ultrasonic Distance Range Finder Sensor for Arduino
RM5.00DescriptionIf you’ve been searching for distance measurement and object detection sensors at a rock-bottom price, look no further! This legendary HC-SR04 ultrasonic sensor is your perfect choice. It offers excellent range accuracy and fairly stable readings at a very low cost. It requires two digital I/O pins (an output pin and an input pin) to interface with it.
An ultrasonic sensor is created based on the principle of echolocation used by animals like bats and dolphins. Since the ultrasonic sensor uses sonar to determine the distance to an object, its operation is not affected by sunlight, spotlight, and object’s surface color which will affect the readings of any infrared distance sensors. However acoustically soft materials such as clothes can be difficult to detect.

830 points Breadboard
RM8.00DescriptionAre you a beginner in building circuit design?
A breadboard is ideal for a beginner to learn in building circuitry. The breadboard does not require soldering to make connections. Sometimes, it is called a solderless breadboard. You can just experiment with your circuit design by plugging in the components without any soldering. Thus, this breadboard and the components are reusable, you can modify your circuit easily without any hesitation. With this feature, it is suitable for beginners like students to build the prototype on the breadboard in order to test the circuit design.
