Interpretive Summary:

Technical Abstract: Monitoring crop canopy temperature remotely with infrared thermometers provides a method to characterize the level of crop water stress and is critical input for decision support for site-specific irrigation management. However, most infrared thermometers are wired and it is difficult to place a large number of wired sensors in a cropped field or on a moving sprinkler without interfering with farming operations. An economical wireless infrared thermometer was developed by ARS scientists at Bushland, Texas. The technology was transferred to Dynamax, Inc., a private company, for commercialization. This presentation discusses the development of the wireless canopy temperature sensor, its calibration and proper aiming in the field to minimize soil background and sun angle effects, and its use as an integral instrument for smart irrigation scheduling.
