People Monitoring Sihlwald

Sensors from the MakeZurich Box

Sensor Product Properties
Radar Sensor RCWL-0516 movment detection only
no distance information
detects human and animals only (due to water)
Infrared Sensor Flying-Fish can be used for distance or proximity measurements
does not work in dark environments
can measure emission of heat by an object
not really suited for outdoor applications...
Laser Sensor Waveshare Laser Sensor 650nm laser diode + detector
range in first tests was below 1m
kind of dangerous...
essentially a light barrier, no distance measurement

Alternative Sensors

Sensor Product Properties
PIR (passive infrared sensor) TBD can detect motion
if raw signal is analyzed, even movement direction could be extractable
Ultrasonic Sensors TBD distance sensor
not too good for human detection (clothes do not reflect sound well)
