Ultrasonic is an ultrasonic distance measuring sensor unit, with the capability of simultaneous reception and transmission. The ultrasonic probe has a sound frequency of 40KHz, a direction angle of ±20 ° and an accuracy of 1mm. The internal part is calculated by an RCWL-9600 ultrasonic distance measuring chip, and the measurement results can be directly obtained through I2C interface (0x57). The effective distance is 30 - 150cm.Product Features * Split transceiver * 30 - 150cm distance effectiveness * Wide angle range * I2C communication, result output directly Includes * 1x Ultrasonic Unit * 1x Grove Cable(20cm) Application * Measuring distance * Avoid obstacles Specification Resources Parameter Ranging chip RCWL-9600 Communication protocol I2C：0x57 Measuring distance 30 - 150cm Sound pressure level of transmitter 108dB Accuracy 1mm Blind area 20mm Receiver sensitivity -68dB Net Weight 9g Gross Weight 23g Product Size 56*24*12mm Package Size 60*55*16mm LEARN AND DOCUMENTS * DOCUMENTS https://elecena.pl/product/22723868/m5stack-ultrasonic-distance-unit-rcwl-9600-discontinued 2023-03-07 https://elecena.pl/product/22723868/m5stack-ultrasonic-distance-unit-rcwl-9600-discontinued 2024-09-19
