HC-SR04 Ultrasonic Distance Sensor Module (Pack of 20)
HC-SR04 Ultrasonic Distance Sensor Module (Pack of 20) This is a Ultrasonic Distance Sensor Module of 20 Quantity. Ultrasonic Module HC-SR04 Distance Sensor can measure the distance to an object by using echo. It can measure the distance between the sensor and the object by the time from the sound wave of a specific frequency to the time when the sound wave is heard to bounce back. The HC-SR04 Ultrasonic Distance Sensor Pack of 20 is perfect for all kind of projects that need distance measurements, e.g. avoiding obstacles. HC-SR04 provides 2cm-500cm non-contact measurement function, the ranging high accuracy can reach to 3mm. Features: Measurement Range: 2 cm to 400 cm (0.8 inches to 13 feet) Accuracy: Approximately 0.3 cm (0.1 inches) Power Supply: 5V DC Current Consumption: Quiescent current: < 2mA Working current: ~15mA Measuring Angle: Effective angle < 15 degrees Dimensions: 45mm x 20mm x 15mm Applications: Can be used with Arduino to make robotic projects based on distance, position & motion sensing. Can be used in obstacle avoiding robot. Can be used in IoT devices using any other Microcontroller board. Take a look at our blog on interfacing ultrasonic sensor with Arduino . Whether you're new to this or already have some experience, this guide will make things clear for you to understand ultrasonic sensor interfacing with Arduino.
