IDEA #4X5F0U Hardware_Software Complex For Estimation Of Chlorophyll And Other Characteristics Of Vegetation Under Field Conditions

HARDWARE_SOFTWARE COMPLEX FOR ESTIMATION OOFF CHLOROPHYLL AND OTHER CHARAC(cid:2)(cid:2) TERISTICS OOFF VEGETATION UNDER FIELD CONDITIONS APPLIED RESEARCH • SENSORSDescription System for assessment of main parameters of vegetation based on remote measurements of its reflectance spectra under field conditions. Principle of measurement is based on original derivative veg(cid:2) etation indices computed with 1(cid:2)st derivatives of leaf reflectance spectra in 500(cid:2)800 nm region. The device is equipped with temperature and irradiance sensors and GPS receiver. Computing block of the device contains original soft(cid:2) ware and allows accumulating data of measurements in data(cid:2) base together with service information. For data recording flesh card or external notebook can be used. Technical parameters of the device: Size: 32x25x20 cm Weight: 8 kg Capacity: 5 W Detail description of the device can be found on web(cid:2)site http://vegetation.kiev.ua Innovative Aspect and Main Advantages • One stage measurement of chlorophyll concentration, averaged for all plants growing on area of 40Ч40 cm • Accumulation of chlorophyll values as well as vegetation reflectance spectra in database together with information concerning irradiance, temperature and geographical coordi(cid:2) nates of area measured. • Time of single measurement is about 4 seconds. • Software contains algorithms for computing chlorophyll, total nitrogen as well as moisture and projective covering of soil by vegetation. (Two last parameters are in process of developing) • The device is transportable and easy in use. Areas ooff Application Agriculture Assessment of main parameters of agricultural crops. Ecology.
