Ultrasonic Module HC-SR04 Distance Measuring Ranging Transducer Sensor DC 5V 2-450cm

This ultrasonic sensor module can be used for measuring distance, object sensors, motion sensors, etc. The high sensitive module can be used with a microcontroller to integrate with motion circuits to make robotic projects and other distance, position & motion-sensitive products. The module sends eight 40Khz square wave pulses and automatically detects whether it receives the returning signal. If there is a signal returning,  a high-level pulse is sent on the echo pin. The length of this pulse is the time it took the signal from first triggering to the return echo.

1. Applications:-

  • Used to avoid and detect obstacles with robots like biped robots, obstacle avoider robots, path finding robots, etc.
  • Used to measure the distance within a wide range of 2cm to 400cm
  • Can be used to map the objects surrounding the sensor by rotating it
  • Depth of certain places like wells, pits, etc. can be measured since the waves can penetrate through the water

2. Use method:-

Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not. The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules. Note: The module should be inserted in the circuit before being powered, which avoids producing a high level of misoperation; if not, then power again.

3. Module Working Principle:-

1. Adopt IO trigger through supplying at least 10us sequence of the high-level signal. 2. The module automatically sends eight 40khz square waves and automatically detects whether receive the returning pulse signal. 3. If there are signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound velocity (340M/S) / 2. Note:-  This module is not suitable to connect with electric power, if you need to connect this module with electronic power, then let the GND terminal of this module be connected first, otherwise, it will affect the normal work of the module.
