This is the SR04+ version of this module, with wide supply voltage from 3 to 5V. It is hardware and software compatible with the old version, and has the same dimensions. The minimum operating voltage of the address 3V allows it to be directly connected to a 3.3V powered MCU.
The HC-SR04+ is an ultrasonic distance measuring module, commonly used for object avoidance, navigation and altitude hold purposes.
Please note: The back of this module might look a bit different that the picture. But, the functionality and size will be identical.
Board connection mode:
VCC, trig (control end)
Echo (receiver end)
Out (empty pin, GND)
Note: The TRIP pin is connected to an internal 10k pull-up resistor. Use the IO port of the microcontroller to pull the TRIP pin low and then give a pulse signal of more than 10us.
The Out pin is a switch output pin when the module is used as a theft protection module. The distance measurement module does not use this pin!
Note: The module should be plugged in on the circuit board to be powered on to avoid high level of malfunction. If it is generated, re-power can be solved.
