2.4 to 4.5 wide voltage input range, the static function GPIO, serial variety of communication methods,
Within the band Watchdog, stable and reliable.
specials :
a. voltage: DC5V
b quiescent current: less than 2mA
c level output: 5V
d level of output: the end of 0V
e. Induction angle: greater than 15 degrees
f detection distance: 2cm-450cm
g precision: up to 1mm
Connection mode:
From left to right number VCC, trig 's (control side), echo (receiving end), GND (ground)
How to use:
High above Port a 10US a control, wait for the high output at the receiving port. An output can be opened to the timer, you can read the timer value when this port becomes low, this the ranging time before they figure out the distance. such a continuous cycle of measurement, you move to the measured value can be achieved
