This paper presents an overview on recent development of wireless sensor technologies and standards for wireless communications as applied to wireless sensors. Examples of wireless sensors and sensor networks applied in agriculture for environmental monitoring, precision agriculture, M2M-based machine and process control, building and facility automation and RFID-based traceability systems are given. The paper also discusses advantages of wireless sensors and obstacles that prevent their fast adoption in agrucultural research. Finally, based on an analysis of market growth, the paper discusses future trend of wireless sensor technology development in agriculture.U radu je dat pregled (današnjeg) skorašnjeg razvoja bežičnih senzorski...
