Dual Element Passive Infrared Motion Sensor / PIR Motion ...

Dual element passive PIR motion sensor LHI778 with TO-5 housing . Description: PIR sensors are more complicated than many of the other sensors explained (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors input and output. The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used ...

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 with load in drain as below. Arithmetic still ...
