HALJIA HY-SRF05 Ultrasonic Distance Sensor Module Measuring Module Compatible with Arduino

Use voltage: DC5V Static current: <2mA Detection distance: 2cm-450cm The performance of this module is stable and the measurement distance is accurate. Can and foreign SRF05, SRF02 ultrasonic distance measuring module and other comparable. The module is with high-precision, the blind zone (2cm) is super close, and stable ranging is a powerful basis for this product to successfully enter the market! Technical Parameters: 1: Use voltage: DC5V 2: Quiescent current: less than 2mA 3: Level output: 5V high 4: Level output: bottom 0V 5: Induction angle: no more than 15 degrees 6: Detection distance: 2cm-450cm 7: High precision: up to 0.3cm The use of this product: a control port sends a high level of 10US or more, you can wait for the high level output at the receiving port. When there is an output, you can start the timer, when the port becomes low, you can read the timing. The value of the device, at this time is the time of the distance measurement, in order to calculate the distance.
