Description This product uses industrial-grade integrated ultrasonic probe design, waterproof, stable performance, all the MCU on the market. The module ultrasonic distance measurement module can provide 20cm-600cm non-contact distance sensing function, ranging accuracy up to 2mm; module includes the transceiver of one of the ultrasonic sensor and control circuit. Mode one usage and the Division’s HC-SR04 module. Lead length 2.5M Features: Waterproof small size, easy to use wide power supply range, low power consumption high precision, high resolution detection of blind spots, farther away the output method of diversification, pulse width output, serial output. Working voltage 3.0-5.5V, working current less than 8mA Frequency 40Khz, sensing range from to 20-600cm Precision 1CM, Resolution 1mm, sensing angle 75degree Trigger sensing signal 10us TTL, send 0x55 Receive measurement signal: MODE-1 (R27 open): pulse width equals to distance. MODE-2 (R27=47K): periodically output range value MODE-3(R27=120K): when receive 0x55, module output 0xFF data_H data_L data_SUM Applications: horizontal ranging; obstacle avoidance, automatic control; close to the object, there is a detective traffic control; security, industrial control; artificial intelligence, teaching and research Documentation please see on this page.
