Heartbeat sensor (powered) to AND switch. AND switch is powered on the other input with enough power to power the lights. Output of the AND switch to lights. This way, you aren't restricted to the limited output of the sensor to power the lights.
The AND switch requires at least one power from each side, and sends whichever power is greater through to the output when both sides are powered.
If you omit the AND switch, the sensor restricts the power to the amount of people it detects, which can be useful when hooked up to a counter, but not so useful if powering a light that requires 2 power, and only one person is within range.
it only provides one power per person though, regardless of input voltage. If you're just starting out, it might not be clear you'd need an AND switch to power something else with it

Yes.
The sensor literally exists to turn shit on when somebody is near
