The Grove Ultrasonic Ranger is a non-contact distance measurement module that operates at 40 kHz and can measure distances from 3 cm to 350 cm with an accuracy of up to 2 mm. It is suitable for various projects such as proximity sensing, ultrasonic detection, distance measurement, and smart car systems.
With a wide voltage range and a single I/O pin, this module is designed for ease of use and is compatible with both 3.3V and 5V systems. The Grove Ultrasonic Ranger is equipped with a plug-and-play Grove connector, making it convenient for beginners and electronic enthusiasts.
For detailed instructions and libraries for Arduino, Python, and Codecraft, refer to the provided documentation in the ATTACHMENT section. Make sure to read the guidance PDF documents provided by Seeed Studio before using the product.
Warning: Do not hot-plug the Grove-Ultrasonic Ranger, as it may damage the sensor. Ensure that the measured area is not less than 0.5 square meters and is smooth.
Hardware Overview: The module consists of an ultrasonic transmitter and receiver, functioning as an ultrasonic transceiver. It utilizes a 40 kHz ultrasonic wave to measure distances by calculating the time from transmission to reception and multiplying it by the speed of sound in the air (340 m/s).
Comparison with HC-SR04: The Grove Ultrasonic Distance Sensor offers advantages such as single-pin operation, support for both 3.3V and 5V systems, and easy compatibility with Raspberry Pi's I/O. In contrast, the HC-SR04 sensor requires a voltage conversion circuit for Raspberry Pi connection.
