Quite small PIR sensor
Sensitivity is not adjustable. Range is a couple of meters. It needs some external intelligence to be useful as a lamp controller (off-time hysteresis).
By changing the position of a 0-Ohm resistor (from L to H) it can be adjusted to re-trigger-able mode. When using a micro this is not really necessary.
