Specifications: Working voltage DC5V Quiet working current 5 m Total working current 30mA Wave transmission frequency 40 kHz Maximum. Measuring distance 5 m blind area 25 cm Size 28.5 x 41 mm Resolution approx. 0.5 cm Angle <50 degrees Working temperature -10 °C ~ 70 °C Storage temperature -20 °C ~ 80 °C Wiring: + 5V (positive power) RX Trigger (Control) Echo (Receive) TX GND (Negative Power Supply) Basic working principle: (1) Using the IO TRIG port, the measurement distance of the trigger, a high-level signal for at least 10uS. (2) The module automatically sends eight square waves at 40kHz, automatically detects whether there is a return signal. (3) When there is a return signal, via the ECHO output of the IO port at a high level, the duration of the high level is the ultrasonic wave time from sending to return.Test distance = (high level time*sound speed(340m/S)/2; This module is simple to use, one port sends a high level of more than 10uS, and then wait for a high-level output to the receiving port. The timer was activated once it was output, and the read time when this port becomes low level, which is the time of this measurement. Use time to calculate distance. Constant cycle measurement can reach your moving measurement values. Package includes: 1 x Distance Measurement Module and Sensor
