Hi!
Does anyone has implemented a person following
behavior? If so I would appreciate any hardware or
software details.
If I'm not wrong, I can modify one of those PIR
detectors used with burglar alarms as it has the
sensing element and amplifiers associated and are
inexpensive as well (~$10). The Eltec sensor, despite
its simplicity of use, is a bit expensive for me
($51!!!).
Any ideas or directions will be welcome.
Best wishes,
Renato
