Abstract
Tlak u biljnom ksilemu može biti korišten kao indikacija reakcije biljke na vodni stres. Ugradbeni sustav za akviziciju ksilemskog tlaka koristi sigma delta modulator za adaptivno namještanje frekvencije otipkavanja ulaznog signala sa senzora tlaka. On, kada je to potrebno, budi mikrokontroler iz režima niske potrošnje kako bi se obavila osnovna obrada signala. Dodane su informacije o drugim parametrima o kojima ovisi tlak u ksilemu; temperatura, relativna vlažnost zraka te doba dana. Korišten je mikrokontroler s trajnom FRAM memorijom kako bi podaci bili zapamćeni i nakon isključivanja sustava. Prikazani su očekivani rezultati te je dan je pregled očekivane i stvarne potrošnje sustava.
Abstract (english)
Xylem pressure can be used as an information of water stress in plants. Embedded system for xylem pressure acquisition is using sigma - delta modulator for adaptive signal sampling frequency and he gives wake up signals for exiting low power mode and do some basic signal processing. Pressure transducer signal is digitalized and saved to non-volatile FRAM memory. Information about other important parameters of xylem pressure, such as temperature, relative humidity and time of day, is also measured and stored into memory. Expected results are shown and also expected and real energy consumption.
