Ultrasonic waves travel faster than the speed of audible sound (i.e. the sound that humans can hear). Ultrasonic sensors have two main components: the transmitter (which emits the sound using piezoelectric crystals) and the receiver (which encounters the sound after it has travelled to and from the target).

An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Ultrasonic waves travel faster than the speed of audible sound (i.e. the sound that humans can hear)

What type of sensor is an ultrasonic sensor?
ultrasonic / level sensors measure the distance to the target by measuring the time between the emission and reception. An optical sensor has a transmitter and receiver, whereas an ultrasonic / level sensor uses a single ultrasonic element for both emission and reception

What is an ultrasonic sensor?

An ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves.

An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity.  

High-frequency sound waves reflect from boundaries to produce distinct echo patterns.

The ultrasonic sensor HC-SR04 includes four pins:
  • VCC pin.
  • GND pin.
  • TRIG pin: this pin receives a 10-microsecond pulse from controller to emit ultrasonic wave.
  • ECHO pin: this pin outputs a pulse when receiving echo ultrasonic wave. The duration of pulse is used to calculate the distance.
How the ultrasonic sensor works:
  • If receiving 10-microsecond pulse on TRIG pin , ultrasonic sensor automatically emits 40KHz ultrasonic wave.
  • If there is an obstacle, ultrasonic wave is reflected back.
  • Ultrasonic sensor measures duration of time from emiting ultrasonic wave to receiving the echo ultrasonic wave. And then ultrasonic sensor generate a pulse with the measured duration on ECHO pin.
How to use ultrasonic sensor:
  • Connect TRIG pin of ultrasonic sensor to HT0 pin of PHPoC device. Set HT0 timer to "ouput pulse" mode.
  • Connect ECHO pin of ultrasonic sensor to HT1 pin of PHPoC device. Set HT1 timer to "capture" mode.
  • Use HT0 timer to generate 10-microsecond pulse.
  • Use HT2 timer to capture the pulse from ECHO pin.
  • Calculate distance based on the duration of captured pulse. The duration of pulse is the travel time of ultrasonic wave. Travel speed of ultrasonic wave is about 340 m/s. Travel distance is calculated according to the formula: distance = speed * time
  • Distance to obstacle is half of the travel distance of ultrasonic wave.
