If I wanted to use this as a human detection sensor, what would be the maximum range that I could expect to detect a human?
The further away the object/human the greater the field of view is. So as shown in the picture on the product page, the field of view is 10cm wide when the sensor is 10cm away from the object. This is then extrapolated the further away the object is. The key to detecting people would be to have enough of a temperature difference between the person and the ambient temperature. Overall, however, the object/human to detect shouldn't be too far away, less than 50cm.
