5PCS HC-SR04 ELEGOO Ultrasonic Module Distance Sensor Compatible with Arduino UNO MEGA Nano Robot XBee ZigBee

Elegoo HC-SR04 Ultrasonic Sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being generated and the sound wave bouncing back, it is possible to calculate the distance between the sonar sensor and the object. Ultrasonic Sensor HC-SR04 is great for all kind of projects that need distance measurements, avoiding obstacles as examples. HC-SR04 provides 3cm-450cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit. As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. The distance can be calculated with the following formula: Distance L = 1/2 T C where L is the distance, T is the time between the emission and reception, and C is the sonic speed. (The value is multiplied by 1/2 because T is the time for go-and-return distance.) Elegoo Ultrasonic Sensor HC-SR04 is inexpensive and easy to use since we will be using a Library specifically designed for this sensor, which can be downloaded from elegoo.com. To use it for Arduino projects you would need an ELEGOO UNO R3 controller board. ELEGOO STEM kits provide all the necessary components, sensors, wires, and boards for you to get started with programming, learning electronics, and creating IoT projects. We strive our best to make STEM education easy to learn and accessible to the young generation. Visit the Store Visit the Store Visit the Store Chris, the founder of ELEGOO, found out that most enterprises in the STEM industry focused on the hardware of open-source electronics and did not have tools to create a complete product by combining electronic hardware and structural shells. We have excellent R&D team, constantly upgrading and improving products, and after-sales service team for quick support. 100% compatible with Arduino, ELEGOO's kits are best-practice for beginners who have no appropriate technical tools to learn about electronics.
