Sensor HC-SR04P - ultrasonic distance measurement 2-450 cm

Ultrasonic distance sensor HC-SR04P for Arduino - 2cm to 450 cm

Universal ultrasonic distance sensor operating from 2 - 450 cm. It is used to measure the distance to an obstacle, allows you to build alarm systems, robots, models, etc.

• Sensor commonly used to measure distance from obstacles (e.g., in autonomous robots)
• The output is a signal whose duration is proportional to the measured distance.
• Powered by 3-5.5 volts.
• Sensor is not susceptible to solar interference and object color.
• The sensor can be connected with any startup kit such as Arduino, or Raspberry Pi minicomputer.
• The leads are 2.45 mm goldpin connectors
• The HC-SR04P sensor is compatible with Arduino
• For the sensor we offer practical sensor holder

Technical data

• Supply voltage: 3-5.5 V
• Average current consumption: 15 mA
• Measurement angle 15*
• Measurement range:
  • 5 V: from 2 cm to 450 cm
  • 3.3 V: from 2 cm to 400 cm
• Output: frequency signal / UART / I2C
• Operating frequency: 40 kHz
• Dimensions: 45x20x15 mm
• raster connector 2.54mm
• The sensor itself supports a range of 2 to over 500cm, but is limited by the standard library to 300cm

Description of the leads on the HC-SR04 sensor board

• Sensor output:
  • VCC - supply + 3.3V
  • Trig - input signal to the sensor
  • Echo - sensor response
  • GND - power supply ground

Notes for connecting the sensor - How the sensor works

• To start the measurement, apply a voltage pulse (5V high state) to the TRIG pin for 10uS.
• The module measures distance using a 40 kHz sound wave.
• A signal is sent to the microcontroller in which the distance depends on the duration of the high state and can be calculated from the formula:
• distance [cm] = ( high level time [us] * 34 ) / 1000 / 2
