Super Sensitive Ultrasonic Devices detect a toothpick at 2 meter range
 

He-us23 Highlights

  • Only two digital I/O port pins are needed to operate the transceiver.
  • Enclosures for industrial applications, IP54, NEMA4 and NEMA12 compliant.
  • Internal sonic wave transmitter and signal conditioner.

He-us23 Applications

  • Liquid Solid Level Monitoring 
  • Object velocity and positioning
  • General Purpose Sonar Echo Ranging
  • Occupancy detection, Security Intrusion Alarm
The first step in the He-us23 operating procedure is to apply a 5 volt pulse to it's transmit wire, this will cause the HE-US23X to transmit a powerful sonic wave. The second step is to wait for the echo to return

To transmit a sonic wave, connect the HE-US23X's orange wire to a 5 volt source. When 0 volt is applied to this wire it will stop emitting the wave. The output pin from a microcomputer, can be used to key the ultrasonic wave. The received echo is amplified and presented on the HE-US23X analog output wire. The device has a digital output, where the peaks and valleys of the echo are presented as 5 and 0 volts respectively.
Minimal interface requires only two digital I/O port pins , one to drive the transmission of the sonic wave and the other for reception of the received wave; in this case no A/D or D/A conversion is needed. For advanced applications the received wave can be monitored and measured using an analog to digital converter.

The HE-US23X is driven by a 5 to 16 volt D.C. source. An unregulated 9 or 12 volt D.C. adaptor, available from your nearest supermarket will do just fine.
