Is the Drain of the PIR the OUTPUT of it, Source would be the voltage supply (5V), Ground would be the Ground.
Drain is OUTPUT signal. [font=Verdana]NO Source is +5 V. [/font]A resistor between Source & GND. A resistor between +5 V and Drain.
Op-Amp operated at dual voltage : + side / gnd / - side ex: +5 . gnd . - 5
Drain is OUTPUT signal. A resistor between Source & GND. A resistor between +5 V and Drain
I use a 741 <-- Not working...
a LM1458 <--- Not Working
TL072 <--- Not working
LM324 <--- Not Working...
These will only work with a minimum of +/- 12V rail, did you have this?
the device outputs 2.2mv/V at full loadexcitation voltage 5 - 15 V
do op amps come with a multiplication factor ?
