Is it possible to cause PIR sensors (of this sort) to detect presence instead of motion? I would like for the sensor to detect the continuous presence of a body, instead of only triggering when the body moves. I thought occluding one of the internal detectors might work, but so far I have not been successful doing so.
If this is too problematic, are there better alternative sensors for this task? I intend to have several of these installed in the same room, so sensors that might interfere with each other (such as the ultrasonic proximity sensors) are not an option.
Any help is appreciated
