light dark sensor with relay circuit
The schematic diagram has been modified to include a 220µF smoothing capacitor connected between the base of transistor Q1 and ground. This addition effectively mitigated the issue of relay chatter, which involved rapid on/off switching at light levels. The incorporation...
Light sensor switch circuit
This light sensor switch circuit enables the automatic activation of a lamp when ambient light levels are low, such as during nighttime. The circuit keeps the lamp illuminated for a predetermined duration. When transistors T4 and T5 are activated, the...
Comparator light sensor
The circuit is designed to sense ambient light levels and activate lights when it is dark. A prototype was successfully built on a breadboard using an LM324 comparator, various resistors, a trimmer resistor, and a photocell. Subsequently, a PCB was...
Super Light Sensor
This Super Light Sensor responds to minute fluctuations in light levels, automatically adjusting from approximately 200 lux to 60,000 lux (from a modestly lit room to direct sunlight). It has various potential applications, such as detecting a car entering a...
Light activated switch circuit
A simple light-activated switch circuit with a diagram and schematic using IC LM311 wired as a voltage comparator and an LDR that acts as a light sensor.
The described circuit utilizes the LM311 integrated circuit, which functions as a voltage comparator,...
Flash slave driver
In photography, a separate flash, triggered by the light of a master flash, is often required to provide additional light and fill in shadows. The sensitivity of this circuit depends on the proximity of the master flash and the value...
Light Follower Robot
The figures above illustrate the fundamental concept of a robot, which consists of various input and output devices connected to a central processing unit, commonly referred to as the brain. These inputs and outputs are essential for the robot's functionality...
Electronic flash trigger
A negative pulse at the input is fed through capacitor C1 to the input pin (2) of the integrated circuit (IC). Pin 2 is maintained slightly above its triggering voltage of 1/3 Vcc by a voltage divider consisting of resistors...
Optical proximity detector circuit diagram
A reflex isolator detects the presence of an object by reflecting light from the object back to the sensor. This technique is effective when an object is in close proximity to the sensor.
Reflex isolators, also known as proximity sensors, utilize...
