An infrared sensor is used for emitting and detecting IR radiation. By this principle, IR sensor can be used as Obstacle detector. There are two types of IR sensors as Active and Passive IR sensors. Passive IR sensor: When sensor does not use any IR source to detect the emitted energy from the obstacles it acts as a Passive IR sensor. Examples ...
• moisture content the more moisture an object contains, the greater its ability to absorb energy and become a good emitter. Wet soil particles have a high emissivity similar to water. • compaction the degree of soil compaction can effect emissivity. • fieldofview the emissivity of a single leaf measured with a very high resolution thermal radiometer will have a different emissivity than an entire tree crown …
