A variety of motion detecting sensors are commercially available, made by such companies as Leviton. I don't know how proud they are of them, but they may be way cheaper than if you made some yourself (and UL approved - useful if they start a fire). Of course, you may want to make one yourself ...
problem with commerical units is that if you don't move around much - the lights go off. Many times I would sit and read a book - ooops - the lights go out - have to move around to keep them on. May want something that also detects infra-red.
They do detect Infra-red. They have two detectors, and they detect a difference in infrared between the two, i.e. movement. The programmable one I offered above allows you to set the delay, and override the motion when needed.
The discussion focuses on selecting effective motion sensor options for automatic room lighting to reduce electricity consumption. Commercially available motion sensors, such as those from Leviton, offer UL-approved solutions that detect infrared radiation changes caused by movement. These sensors typically use dual infrared detectors to sense motion by detecting differences in infrared levels. A common issue with commercial units is that lights may turn off during periods of minimal movement, such as reading, which can be mitigated by adjustable delay settings or manual override features. DIY solutions using Arduino-based motion sensor lighting control systems are also presented, providing customizable control with manual and off override capabilities. Additional resources include detailed diagrams, datasheets, and example projects to assist in implementation. The discussion also references sensor suppliers like South Ocean Sensor for further options. Summary generated by the language model.
