Simple light-switch circuit
The circuit is a light switch that activates when the light intensity drops on a photoresistor. It features a straightforward construction and can be utilized in numerous applications. The photoresistor and the trimmer function as a voltage divider and also...
mini projects
This circuit automates the control of street or porch lights. It utilizes a 7806 voltage regulator IC to manage the operation of street lights, tube lights, or other household lighting systems. The 7806 IC provides a stable output voltage despite...
OVER LIGHT SENSOR ALARM CIRCUIT
The Light Dependent Resistor (LDR) is a variable resistor whose resistance decreases as light intensity increases. Under normal light conditions, the resistance of the LDR is sufficiently high, resulting in an inadequate voltage across resistor R to activate the Silicon...
light intensity meter
This simple light intensity meter circuit can be used to determine the intensity of light in a wide variety of electronic projects and experiments.
The light intensity meter circuit is designed to measure ambient light levels and can be employed in...
light sensor circuit
This is a sensor circuit designed for light detection. It utilizes the LM311 comparator and features a simple design. The comparator is powered by a 12 V DC supply and does not require a negative supply for efficient operation. Feedback...
Light Sensor Circuits
Dark Activated Switch or Porch Light Switch. This circuit activates a relay when the light level drops below a preset threshold. The light sensitivity can be adjusted using variable resistor VR1, and the relay contacts can control an external light...
lights led circuits schematics
The circuit employs two Light Dependent Resistors (LDRs) arranged in series with a separation of approximately half a meter. This configuration allows each LDR to detect the presence of a person entering or exiting the room. The processed outputs from...
Light-Controlled Pond Pump
This circuit was designed to control a pump in a garden pond, enabling it to automatically activate at dawn and deactivate at dusk.
The circuit utilizes a light-dependent resistor (LDR) to detect ambient light levels, which serves as the primary sensor...
Light/Dark Switch With Relay
The circuit functions as a light detector. Under normal conditions, the resistance of the light-dependent resistor (LDR) is high, which keeps pin 2 low. When light falls onto the LDR, the resistance decreases to a few hundred ohms, triggering pin...
