Happy New Year!
I need some help trying to sort out technology that I can use for the human/obstacle sensor. I am building a vanity mirror lighting circuit and want it to turn on the LED lights only when person stands in front of the mirror.
I've been looking around and see that there are multiple options. I've seen sensors that are based on IR or ultrasound. I took a chance and bought some IR sensor from amazon. It appears that I somehow missed that it was only working within 30 cm or so. After digging some more it feels like most if not all IR sensors are only working at a close range.
Anyway, I was wondering if someone can provide me some guidance for choosing what technology best fits for the task.
I have a vanity mirror with an opposite wall about a 1 meter (3-4 feet) away. I am not looking at the occupancy sensor, the one that switches when motion is detected. However I may consider it if no other viable options found. I need a sensor that will trigger when someone stands in front of the mirror. The range should be 0.5-1 meters. Also, preferrably that its not complicated to build for a relative beginner.
I am not expecting a full circuit (however would really be helpful) but some direction and explanation will be sufficiend for now.
Thank you in advance!
