I found this circuit which detects guest arrival.
Could anyone please explain the action of the capacitors, in the circuit on the right, when the path between the led and the tsop1736 is broken.
Also the datasheet for the tsop suggests using a rc network across pin 1
and 2 of the tsop to suppress power supply disturbances,
Is it unnecessary in the design of this circuit or inadvertently omitted.
If so is there any harm in me adding it.
Thnx.
