Digital Light Sensor
The Intersil ISL29001 is a digital light sensor designed to measure light intensity and easily interface with a microcontroller.
The Intersil ISL29001 is a highly integrated digital light sensor that operates using a photodiode and an analog-to-digital converter (ADC) to provide...
Light Barrier Detector
This simple circuit using a single transistor turns ON the relay when light falls on the LDR. The potentiometer is adjusted for the required sensitivity. The power supply is 6V. Be careful about the impedance of the relay. Its impedance...
Energy Saving Night Light circuit
The lamps are usually used as ballast or electronic ballast inverter. Here it is used to reduce voltage capacitor reactance. Interesting is also the method of ignition of the auxiliary electrodes involved over 150 Ohm resistors. To start simply involve...
Bridge Head
The LDRs were hand-picked. Got two packages of them from Radio Shack, looking for at least two pairs of similar parts. Then added wire-wrap pin sockets to the circuit so that the LDRs could be plugged in. Currently, the 0.33µF...
Light Level Droplets Detector
This circuit is a Low-Light Level Drop Detector. It utilizes a self-biasing configuration to detect small changes in light levels.
The Low-Light Level Drop Detector circuit is designed to sense minute variations in ambient light conditions, making it suitable for applications...
LDR PC Desk Lamp
Most of the PC desk lamps available in the market illuminate whenever there is input power. These do not consider whether there is an actual need for light.
The typical design of PC desk lamps operates on a straightforward principle: they...
automatic night lamp 230v
This project involves a simple automatic night lamp circuit, also known as a dark-activated 230V lamp circuit. The circuit is designed to automatically activate an AC lamp or bulb at sunset or when it detects a lack of light. It...
Light Pollution Meter
My circuit adds a transistor, to add feedback, and two resistors, to tailor the range of the control, with the result that a single-turn potentiometer gives a control range of about 2 to 30 microamps. I installed my circuit in...
Electronic Schematic Diagram of Light Detector Robot using Light Dependent Resistor (LDR)
The electronic schematic of the Light Detector Robot can be divided into three main components: the sensor, the microcontroller, and the DC motor driver. The light sensor utilized in this design is a Light Dependent Resistor (LDR), which alters its...
