Product Description

Special Note: This module is not provided and the circuit schematic, there are no words chip, if required, and the schematic diagram of the customers do not buy it, because we do not,

1, the module performance is stable, measure the distance accurately. Can and foreign 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!

2 Main technical parameters:
1: Voltage: DC5V 2: Static current: less than 2mA
3: Output Level: High 5V 4: level output: the end of 0V
5: Sensor angle: 15 degrees is not greater than 6: Detection Range: 2cm-500cm

7: High: up to 0.3cm

Board wiring, VCC, trig (control side), echo (receiving end), out (empty legs), GND

OUT pin for this module as the security module of the switch output pin, pin distance measuring module without this!

Note: The module should be re-energized the circuit board inserted Fortunately, to avoid high malfunction, if generated, re-energized be resolved.

3, URF04 module works:

(1) The IO trigger location, the high signal to at least 10us;

(2) the module automatically sends eight 40khz square wave, automatically detects whether a signal return;

(3) a signal back, through the IO of a high output, high duration of the ultrasound is the time from launch to return.

Test distance = (time * High speed of sound (340M / S)) / 2;

The product is simple to use, a control population of more than send a 10US high, you can wait to receive high output port. A timer can be opened with the output timing goes low when the port can be read when timer value, this time to the time for this distance, only calculate the distance. This constant cycle of measurement, you can reach the value of the mobile measurement ~ ~

1, the module performance is stable, easy to use, measure the distance accurately. Can and foreign SRF05, SRF02 ultrasonic distance measuring module and other comparable, and affordable, your ideal choice for the procurement of ultrasonic devices. Module precision, blind spots (2cm) super close, stable ranging success of this product to market under the strong!

    Just watched it and congrats on Mickey picking up his Oscar. Seen most of them but this was raw talent without a pretty face.
