Guys, I get email fliers from MPJA about every two weeks. If you're not familiar with them you should know that some of their items are not stock items. When they're gone, they're gone. The item description usually states this when applicable.
Since we get quite a few postings regarding PIR Detectors I thought I'd alert the group of THIS little 3 pin module.
The MPJA data sheet is located HERE.
Caution! The data sheet shows no base current limiting resistor is used in their BJT interface example. I think it wise to test the current output to verify that the source impedance is high enough to connect directly to a Base.
