Descriptions Arrela® Hc-sr04 Arduino Ultrasonic Distance Measuring Sensor Module
This is also an important factor to consider, as consumer self-confidence in certain companies over others dictates that more of their products have been purchased and used with satisfaction. You will surely have more security buying from one of these popular suppliers.After you have done all the search, there is one final thing to check out and perhaps use to complete your selection process. Suppose you have narrowed your decision right down to 3 products , but are uncertain how to pick the one to buy.
1, the module performance is stable, measure distance accurately. SRF05, SRF02 ultrasonic ranging module and abroad comparable. Module precision, blind spots (2cm) super close, stable ranging success of this product according to market powerful! This module is completely Qian Yung GH-311 anti-theft module
2 The main technical parameters:
1: Voltage: DC5V 2: Static current: less than 2mA
3: level output: high-5V 4: level output: the end of 0V
5: Sensor angle: not more than 15 degrees 6: Detection distance: 2cm-450cm
7: High precision: up to 0.3cm
Board wiring, VCC, trig (control side), echo (receiving end), out (empty feet), GND
Note: TRIP pin internal pull-up 10K resistor TRIP pin is pulled down by the microcontroller IO port, and then give a 10us pulse signal.
OUT pin for this module as an anti-theft module when the switch output pin, ranging module without feet!
Note: The module should be inserted Fortunately, the circuit board is re-energized, to avoid high malfunction, if you had a re-energized before solve.
This module provides a ranging process: C51, PIC18F877 microcontroller Yoshitatsu, three MCU Test Reference.
3, URF04 module works:
(1) IO to trigger ranging, to the high level signal of at least 10us;
(2) the module automatically sends eight 40khz square wave, automatically detects whether a signal return;
(3) outputs a high level signal is returned, through the IO, the high level duration of the ultrasonic wave from the transmitter to the return time.
Test distance = (high level time * sound velocity (340M / S)) / 2;
