Correct Misterbill2, the sensor itself does not include a relay. If you refer to the schematic in post #5, the sensor is being used to trigger a separate relay. If I understand you correctly, you are saying to replace the resistor I am using that is shown in the schematic in post #5 with one of higher value. When you say an external gate, does that mean a relay? Also, prairiemystic mentioned an issue with sunlight that makes me think I should be looking at passive IR sensors versus active IR sensors. The location definitely will be in the sunlight at times.The sensor shown in post #16 does not include a relay. That means that relay coil current is not an issue. So now there is confusion on my part. previously there was reference to a relay, and also a circuit that included a relay. If it is just the current through the comparator output resistor then that resistor can be replaced with a higher valued one and feed an external gate to provide compatible drive outputs.
