Controlling LED Intensity with Light Sensors

AI Thread Summary
Light sensors are essential for controlling LED intensity based on ambient light conditions. A Light Dependent Resistor (LDR) is a viable option for sensing light levels, allowing for adjustments to the LED brightness. Additionally, photodiodes can be used to generate current in response to light intensity, providing another method for this project. If these sensors are not available, alternative approaches may involve using microcontrollers to process light data and adjust LED output accordingly. Implementing these solutions can effectively manage LED brightness in relation to surrounding light sources.

Hi I would like to know if there is a sensor available in the market that would help control the intensity of light given out by a white LED, taking into account the light coming from the surrounding ambient light. As an example I am trying to implement a project in which I would have to control the intensity of light given out from a white LED which is placed above a computer monitor screen, based on the intensity of light given out from the computer screen, I would have to control the LED light. I would also like to know if the sensor is not available in the market how am I supposed to go about implementing this project.

A photodiode generates current due to the light intensity that it senses, maybe u can try it.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
