HS-SR04P Ultrasonic Distance Sensor Module - PH2.0 Connector

The HS-SR04P is an enhanced version featuring optimized circuitry for improved measurement stability and accuracy. It maintains full physical and functional compatibility with the HC-SR04, including the same pinout and dimensions, but offers better performance, particularly in signal consistency and a potentially reduced blind zone.

The module is designed for dual-voltage operation, compatible with both 3.3V and 5V DC power supplies and logic levels. This flexibility allows it to interface directly with a wide range of microcontrollers, from 3.3V-based systems like ESP32 and Raspberry Pi to traditional 5V Arduino boards.

Connect the module's VCC to Arduino 5V, GND to GND, Trig to a digital output pin, and Echo to a digital input pin. The Arduino code sends a 10µs high pulse to the Trig pin, then uses the `pulseIn()` function to measure the duration of the high pulse returned on the Echo pin. Distance is calculated using the speed of sound.

While exact specifications can vary, modules based on this design typically offer a non-contact measurement range from approximately 2cm to 400cm. Accuracy is generally within a few millimeters under stable environmental conditions. Performance can be affected by target surface texture, angle, and ambient temperature.

The module is supplied as a standalone unit with a standard PH2.0 female connector. You will need a matching PH2.0 4-pin male connector cable or individual Jumper wires to interface it with your development board or control system. No other external components are typically required for basic operation.
