CLUSTER-ACOUSTIC REMOTE CONTROL - PRINTED PLATE

Producer: AVT

This exceptionally attractive and simple project will amaze colleagues and family. The system responds to a loud clap. At the same time, it displays an amazingly low sensitivity to sounds typical of the environment (speech, calm music). Each subsequent release changes the state to the opposite. This is signaled by a two-color LED diode. After completing with the executive system, eg a relay, the kit AVT721 is ideal for remote control of a night lamp, blinds, etc. The system has a reset circuit after turning on the power.

The device is especially recommended to electronics practitioners, experimenters and anyone who wants to remotely switch on and off

Selected parameters:

  • a two-terminal electret microphone
  • range about 5 m
  • triggering with a clap, the system practically does not react to other sounds
  • two-color status indication via LED
  • optional output circuit: relay or power transistor
  • power supply - 7-15 V
  • printed circuit board and documentation included
    A version with a set of independent components is available
