OPTIONS
• If a capacitor of 1 µF or more is connected between 0 V and
output or between +V and output, connect a 100 Ω resistor in
series as shown below.

1 μF or more
the charge or discharge current
of the capacitor, so that it
results in delaying the response
whenever the sensor switches.
The connected resistor solves
this problem.
