Pseudonymous maker “Sindhu” has put collectively an ambient lighting management system, dubbed Sirius, powered by a Raspberry Pi 4 with an Arducam digital camera module connected — and supporting each customary and dimmable lamps.
“The aim of Sirius is to regulate ambient lighting,” Sindhu explains. “Sirius controls lighting by periodically taking a photograph and calculating ranges of brightness within the picture. Then the lamp close to my desk is turned on if the ambient brightness drops. The lamp can also be turned off when the brightness hits the max threshold. Why is that this necessary to me, you ask… as a result of I desire working in a nicely lit (principally brilliant) setting.”
Whereas a Raspberry Pi and a digital camera module might sound overkill for an ambient gentle monitoring venture — “I first began with photoresistors,” Sindhu explains, “however I actually wished to make use of a mini cam[era]” — it is undeniably efficient: Nonetheless photographs captured from the digital camera module are analyzed, utilizing both the Python Picture Library (PIL) or OpenCV, for brightness ranges, that are then used to drive a related lamp.
On the lighting aspect, two variations have been constructed. The primary makes use of a regular, non-dimmable lamp related to a TP-Hyperlink Kasa good plug and addressed utilizing the python-kasa library; the second makes use of a dimmable Mi good LED lamp and the python-miio library, permitting for direct management over brightness somewhat than a easy on-off binary.
“I began off utilizing our current lamp which was related to the outlet through a sensible plug,” Sindhu explains. “However then I noticed that I wished to additionally attempt the identical method with a dimmable lamp. Fortunately I already had one — and by I, I imply my husband had one. A lot to his dismay, I ended up utilizing it for this venture.”
Full particulars on the Sirius venture can be found on Sindhu’s construct log.
