Web3 apr. 2024 · Just multiply your theoretical spot size ratio in millimetres by three, which gives you a spot size ratio of 3 x 3 pixels instead of 1 x 1. This number is going to be more accurate. So if you multiply IFOV in mm (19.62) by 3, you get: 58.86 mm. This means you can measure a 58.86 millimetre spot from 15 metres away.
Web3 apr. 2024 · SEEING THROUGH DUST Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can also reveal objects in the universe that cannot be seen in visible light using optical telescopes.

Answer: Infrared sensors can sense up to 30 feet. Passive infrared sensors can detect movement up to 30 feet away. When a PIR detector is placed in a room, the sensor will be able to “see” the entire room. Most homes will only need to use one IR sensor to cover an entire room.
