HC-SR04 Plus Ultrasonic Sensor Module HC-SR04+ for Arduino Ultrasonic Distance Measuring Board 3.3V 3.5V Electronic DIY PCB
Product introduction:
The HC-SR04+ is a wide voltage operation ultrasonic ranging module.
The module's external dimensions and software are fully compatible with the old version of the HC-SR04; it can be seamlessly switched with the old version of the HC-SR04. The minimum operating voltage of the address 3V allows it to be directly connected to a 3.3V powered MCU.
Features
Detection angle is less than 15 degrees
Industrial MCUs
Working temperature -20~80 degrees Celsius
Detection distance: 5V 2cm~450cm; 3.3V 2cm~400cm
Wide Voltage Operation: 3V-5.5V Full Compatibility with HC-SR04 Software and Hardware Dimensions
Board connection mode,
VCC, trig (control end)
Echo (receiver end)
Out (empty pin, GND)
Note: The TRIP pin is an internal pull-up resistor of 10K. 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 foot is a switch output pin when the module is used as a theft protection module. The distance measurement module does not use this foot!
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.
