6 FAQs about [Photocell sensor accuracy]
Are photocell timing systems accurate?
Photocell timing systems are used routinely to measure running speeds. In this study, the accuracy of such systems was evaluated using centre of mass speed estimates from three-dimensional video analysis as criteria. One subject ran at five nominal speeds (5-9 m x s (-1)) for each of five separations (1.6-2.4 m) between consecutive photocells.
How much does a photocell sensor typically cost?
The cost of a photocell sensor typically ranges from 1.99 to 200. The price can vary depending on different parameters. Stay updated to what's new and popular on the market.
Can a photocell sensor be used to measure light levels?
Each photocell sensor will act a little differently than the other, even if they are from the same batch. The variations can be really large, 50% or higher! For this reason, they shouldn't be used to try to determine precise light levels in lux or millicandela. Instead, you can expect to only be able to determine basic light changes
What is a photocell sensor?
Photocells are basically a resistor that changes its resistive value (in ohms Ω) depending on how much light is shining onto the squiggly face. They are very low cost, easy to get in many sizes and specifications, but are very innacurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch.
Is the photocell sensor UL listed?
Our photocell sensor is UL listed to ensure quality and your safety. | UL listed for a wide range of residential and commercial applications. | The photocell sensor senses sunlight and automatically turns lights on at dusk and off at dawn. Ideal for outdoor lamp post lighting, wall packs or wall scones.
Are photoresistors accurate?
Photoresistors are usually low cost binary sensors used to determine if it is light or dark in the environment. If you want to know the difference between day and night you do not require a lot of accuracy. Are there photocell types whose variability is less than others? Yes, which is why for light measurements photodiodes are used.
