Is there a place to add photo resistor in the board?

It's configured with a photo resistor so it doesn't trigger during daylight. In my application I want mine to trigger anytime someone enters the bathroom, so I jumped it out of circuit. If you hold the board with the potentiometers up there is a row of resistors just below them. The one on the right being the photo transistor. The the body is clear, so it can detect light, that makes it easy to spot. It's placement on the opposite side of the board than that of the sensor, kind of makes it worthless.

Is this affected by heat? i have an am312 that throws false positives when my hvac turns on.

Yes, the Passive InfraRed (PIR) sensor detects hot things moving. If your HVAC moves hot air in front of the detector, it should be detected.

What does it need to be powered up? like 5v 12v or ac voltage.

Hello, the operating voltage range of this HC-SR501 motion sensor is DC 4.5-20V

What is the spacing on the 3 header pins? (Ground, Signal, Power)

It is 2.54mm pitch on the 3 header pins. Thanks
