HC-SR04-Ultrasonic Range Finder

The HC-SR04 Ultrasonic Range Finder uses sonar to determine the distance to an object, similar to how bats or dolphins navigate. It emits ultrasonic waves from the transmitter, which then bounce off objects and are received back by the sensor. The time taken for the echo to return is used to calculate the distance.

Ultrasonic

• Expose To Extreme Conditions: Avoid exposing the sensor to extreme weather conditions as it may affect its functionality.,
• Use On Soft Materials: Avoid using the sensor to detect acoustically soft materials like cloth, as they can be difficult to detect.

• Ensure Clear Path: Make sure the path between the sensor and the object is clear of obstructions for accurate measurement.,
• Use Within Specified Voltage: Operate the sensor within the recommended voltage of 5V to avoid damage.,
• Mount Properly: Use a mounting bracket to attach the sensor securely to your project.

• Range Accuracy: Up to 3 mm

• Minimum: 2 cm,
• Maximum: 400 cm

• +5v: Connect to the positive power supply.,
• Trig: Connect to a control pin on your microcontroller for sending the pulse to trigger distance measurement.,
• Echo: Connect to a receiving pin on your microcontroller to read the pulse width representing the distance to the object.,
• Gnd: Connect to the ground of the power supply.
