The HC-SR04 ultrasonic distance sensor is a cost-effective solution for measuring distance in a non-contact manner. With a range of 2 cm to 400 cm and an accuracy of up to 3mm, this sensor is perfect for a wide range of projects. The module includes an ultrasonic transmitter, receiver, and control circuit, making it easy to set up and use. With only four pins to worry about, including VCC for power, Trig for triggering, Echo for receiving, and GND for ground, this sensor is a great choice for beginners and experienced makers alike. Additionally, the sensor’s control circuitry helps to prevent inconsistent data in certain applications. With an operating voltage of 5V DC and operating current of 15mA, this sensor is suitable for use in a variety of projects. The 15° measure angle and 2 cm – 4m ranging distance makes it perfect for most projects.
