AUTOMATION
LIGHT SWITCH
A simple and inexpensive circuit, suitable for many
applications like the automatic switching of the lights in
a shop-window or a room, according to the ambient
light level, for alarm systems, production control,
remote controls etc.The circuit uses a light dependent
resistor that changes its value according to the amount
of light it receives, and three transistors which are used
to amplify the signal from the LDR and operate a relay.

TOUCH SWITCH
A circuit capable of opening and closing any circuit by
simply touching its contacts.The relay contacts are
rated at 250V 2A. It can also be used for remote
control applications.The “heart” of the circuit is the
integrated circuit CD 4001.A small transistor is driven
from the output of the IC and this in turn is used to
activate the relay. Max. current: 30 mA.

SOUND SWITCH
This is a switch that can be operated by means of
sound. It can be used to turn an apparatus ON and
OFF from a distance. Suitable for alarm systems. It can
be adjusted to respond to voice, hand clapping or
almost any sound.Very sensitive.When activated it will
stay in this condition until it receives another sound.

ELECTRONIC THERMOSTAT
This is a switch that will be activated when its sensor
reaches a certain temperature.The sensor is a very
sensitive THERMISTOR.The circuit consists of three
transistors, the last of which is used to activate a relay
having 250V/2A contacts.The temperature that will
trigger the circuit can be adjusted.Very useful in safety
devices when a certain temperature level must be kept.
