Lighting voice-activated switch circuit using relay
Source: InternetPublisher:闪电杰克 Keywords: Voice control switch switch circuit relay Updated: 2021/09/05
It uses relay control. The characteristics of this voice-activated switch are: when clapping for the first time,
the load is turned on (the light is on); when the hand is clapping for the second time, the load is cut off (the light is off). It can be used for corridor or residential lighting control.
The sensor (microphone B) can use a head-mounted microphone or a carbon microphone, or a CR22-9 condenser microphone used in recorders
