nThe module performance is stable, measure the distance accurately:
nCan and SRF05, SRF02 ultrasonic distance measuring module and other comparable. Module precision, blind spots (2cm) super close, stable ranging success of this product to market under the strong!
nStatic current: less than 2mA
nLevel output: high-5V
nLevel output: the end of 0V
nSensor angle: not more than 15 degrees
nDetection distance: 2cm-450cm
nHigh precision: up to 0.3cm
nConnection: VCC, trig (control side), echo (receiving end), GND
n10US a control population of more than a high-fat, you can wait to receive high output port. A timer can be opened with the output timing, when the port goes low when the timer value can be read this when the time for this distance, only calculate the distance. This constant cycle of measurement, you can reach the value of the mobile measurement ~ ~
nThe IO trigger location, the high signal to at least 10us;
nThe module automatically sends eight 40khz square wave, automatically detects whether a signal return;
nAsignal back, through the IO of a high output, high duration is
nUltrasonic time from launch to return. Test distance = (time * High speed of sound (340M / S)) /
nThis module provides a full set of ranging process: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, LED display, serial display, ranging reference program.
