Description
The HC-SR04 ultrasonic sensor is a low-cost, widely used sensor for measuring distances. It works by emitting an ultrasonic sound pulse and measuring the time it takes for the pulse to reflect off an object and return to the sensor. The distance to the object can then be calculated using the speed of sound.
Features:
- Low cost
- Easy to use
- High accuracy
- Long range (up to 4 meters)
- Non-contact measurement
Applications:
- Obstacle avoidance
- Proximity sensing
- Distance measurement
- Liquid level measurement
