It can measure from 3cm to 350cm with an accuracy of up to 2mm. It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detectors.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-G7bpdT6E0oI1CYxcnMRl0YDhgCh\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-G7bpdT6E0oI1CYxcnMRl0YDhgCh\"\u003eThis module has an ultrasonic transmitter and an ultrasonic receiver, so you can consider it an ultrasonic transceiver. Familiar with sonar, when the 40 KHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be emitted back, and the receiver can receive the reflected ultrasonic wave. It is only necessary to calculate the time from transmission to reception, and then multiply the speed of sound in the air (340 m\/s) to calculate the distance from the sensor to the object.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-SBVrdJyNOoGQEMx4nlJlY8iUgfg\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-SBVrdJyNOoGQEMx4nlJlY8iUgfg\"\u003eCompared with traditional ultrasonic modules HC-SR04, the Grove - Ultrasonic Distance Sensor integrates a single-chip microcomputer, and the transmitting signal and the receiving signal share one pin by time-division multiplexing, so only one I\/O pin is occupied. Another difference is that HC-SR04 only supports 5V voltage, while Grove - Ultrasonic Distance Sensor supports 5V and 3.3V. As we know, the Raspberry Pi I\/O only supports 3.3V. Therefore, the Grove - Ultrasonic Distance Sensor can be directly connected to the I\/O of the Raspberry Pi, but the HC-SR04 needs to use a voltage conversion circuit.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-SBVrdJyNOoGQEMx4nlJlY8iUgfg\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv data-type=\"image\" data-ace-gallery-json='{\"items\":[{\"uuid\":\"9960c9d7-e68c-4f59-a6f2-15fa3f8c2d94\",\"height\":402,\"width\":996,\"currHeight\":402,\"currWidth\":996,\"natrualHeight\":402,\"natrualWidth\":996,\"pluginName\":\"imageUpload\",\"scale\":1,\"src\":\"https%3A%2F%2Finternal-api-drive-stream-sg.larksuite.com%2Fspace%2Fapi%2Fbox%2Fstream%2Fdownload%2Fpreview%2FPjfTbaeipokZYcxQiTWlE4TWgYc%2F%3Fpreview_type%3D16\",\"file_token\":\"PjfTbaeipokZYcxQiTWlE4TWgYc\",\"image_type\":\"image\/jpeg\",\"size\":172482,\"comments\":[]}]}' class=\"image-uploaded gallery old-record-id-ZC6RdnHrJoX41zx0kBVl2zXXgJf\"\u003e\u003cimg src=\"https:\/\/github.com\/SeeedDocument\/Grove_Ultrasonic_Ranger\/raw\/master\/optimizing\/Compare.jpg\" alt=\"Grove - Ultrasonic Distance Sensor pinout vs HC-SR04\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-IJomdlElio9RXCxZuSKl2vEPgMe\"\u003e\u003cem\u003eGrove - Ultrasonic Distance Sensor vs HC-SR04\u003c\/em\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-IJomdlElio9RXCxZuSKl2vEPgMe\"\u003e\n\u003cem\u003e\u003c\/em\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-A763dAEXNotQgPxUFa0lkXSngxd\"\u003eWhat's more, we provide full documents and libraries for Arduino, Python, and Codecraft so that you can use the Grove - Ultrasonic Distance Sensor with Arduino and Raspberry Pi easily.
