detection Sample Application with LHI 778 PIR Sensor ...

The line in the LHI778 data sheet labelled "output impedance" tells you what you need to know for interfacing purposes. The sensor is either on or off. When on and when you use a 47 kohm load resistor the FET looks like it is a resistor with resistance between 5 and 10 kohm. Looks like load should be from source to ground with drain at V+ not ...
