Specification :

The HC-SR04 is an ultrasonic distance sensor commonly used in robotics and automation projects. Here are some typical specifications of the HC-SR04:

• Operating voltage: 5V DC
• Operating current: 15mA
• Measuring distance: 2cm to 400cm (0.8in to 157in)
• Resolution: 0.3cm (0.12in)
• Measuring angle: 15 degrees
• Trigger pulse width: 10μs
• Echo pulse width: the pulse width is proportional to the distance of the object from the sensor
• Operating frequency: 40kHz
• Size: 45mm x 20mm x 15mm
• Trigger mode: a single signal trigger or continuous signal trigger
• Detection range: up to 4m (13ft) in optimal conditions.

It's important to note that the performance of the HC-SR04 can be affected by factors such as temperature, humidity, and the surface of the object being detected. Therefore, it's always recommended to test the sensor under the actual operating conditions to obtain the best results
