HC-SR04 Arduino compatible ultrasonic ranging module sensor obstacle avoidance intelligent car accessories

Description

1: the use of voltage: DC5V2: static current: less than 2mA3: level output: high 5V4: level output: bottom 0V5: induction angle: no more than 15 degrees6: detection distance: 2cm-450cm7: high precision: up to 0.3cm8: board connection mode, VCC, trig (control side), echo (receiver), out (empty), GNDNote: the TRIP pin is an internal pull up resistor on the 10K, using the IO port of the microcontroller to pull the TRIP pin low, and then give a pulse signal above 10us. OUT pin for this module as the anti-theft module when the switch output pin, ranging module do not have this pin! Note: the module should be plugged in the circuit board to be re energized, to avoid generating a high level of error, if produced, re energized to solve the problem.1 ultrasonic distance measuring moduleData and Arduino program download address: http://pan.baidu.com/s/1i37ShUH Praise! 10:41:00] [2014-10-10 Buyers:Jason * * *
