Ultrasonic Ranging Sensor Module Hc-Sr04 Ultrasonic Wave Detector Ranging Module Hcsr04 Distance Sensor Measuring Module

New and high quality! Usage of this product: A control port sends a high level of more than 10US, and you can wait for the high level output at the receiving port. Once there is an output, you can start the timer to count. When this port becomes low, you can read the timer value, which is the time for this distance measurement, and then calculate the distance. By continuously measuring periodically, you can move the measured value Module working principle: (1) Using IO triggered ranging to provide a high-level signal of at least 10us; (2) The module automatically sends 8 40kHz square waves and detects whether there is a signal return; (3) A signal is returned, and a high level is output through IO. The duration of the high level is The time from emission to return of ultrasonic waves. Test distance=(high-level time * sound speed (340M/S))/2; This module can provide a complete set of ranging programs: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital tube display, serial port display, etc., ranging reference program. Operating voltage: DC5V Static current: less than 2mA Level output: High 5V Level output: Low 0V Sensing angle: not greater than 15 degrees Detection distance: 2cm-450cm High precision: up to 3mm Wiring method：VCC, trib (control terminal), echo (receiver terminal), GND ground wire Color: As shown Package includes: 1pc Note: As different computers display different colors, thank you for your understanding, the actual product color may be slightly different from the image.
