HT316 Ultrasonic Motion Detector (SPDT) / Electronics Kit


The HT316 is an Ultrasonic Motion Detector with SPDT Relay which can be used to turn the device on or off when any moving object or human bodies was detected. Ideally designed for security alarm system, proximity switch, visitor chime, etc.

Example: When a burglar enter the detection zone, the reflected waves changes it's frequency slightly. This change of frequency cause the circuit to activated the relay for a few seconds.



  • Input Voltage: 9-12VDC
  • Sensing Distance: 30-300cm
  • Used a pair of 40Khz Ultrasonic Transducer
  • Sensitivity is adjustable
  • Reverse Polarity Protection
  • LED Indicator for Relay On
  • With SPDT Relay Output


Assembly Instructions

  • Check off the components in the package against the component listing before assembly.
  • Start with the smallest components working up to the taller components, soldering any interconnection wires last.
  • Place and Solder the components into the board, make sure the components are in right position according to the overlay of PCB
  • The transduces are mounted off board via 2 pairs of header,


Test & Adjustment

  • After assembled, please check & ensure the value & polarity for all components were inserted into PCB correctly, wrong polarity connection of capacitors can caused explosion of failure.
  • Next, ensure all these leads are soldered, no solder bridges between adjacent pads and no dry joint.
  • Once confirmed, connect the power source to the circuit board.
  • If all goes well, this kit starts function as following:
  • When any object enters detection field, the relay coil will be energized to enable the output for a few seconds, also the Red LED indicator on the PCB will turn on.
  • Step above will repeat continuously until the object stops moving or user turn off the power.
  • Adjust the preset (P1) for the sensitivity of the sensor if necessary.
