Abstract:
[Purpose]Smart greenhouse is the future development trend of facility agriculture,and sensing technology and Internet of Things technology are the foundation of smart greenhouse. It is significant to analyze the research progress and application prospect of greenhouse sensor technology.[Method]Greenhouse sensors can be divided into environmental factor sensors and plant body information sensors according to their application fields. The two types of sensors are analyzed from the aspects of accuracy,characteristics,application scope and development trend. [Result]Environmental factor sensors include light sensors,air temperature and humidity sensors,CO 2 sensors,and soil-related sensors. Plant body information sensors include plant temperature sensors,plant moisture sensors,and plant nutrient element sensors. The light sensor is most widely used with silicon photovoltaic cells. Among the air temperature sensors,one of the most promising applications is the semiconductor PN junction temperature sensor. Both resistive and capacitive materials are used in the humidity sensitive materials of the air humidity sensor. CO 2 sensors are mainly infrared sensors. In soil and plant information sensors,spectroscopy plays an increasingly important role. [Conclusion]In the future,the field of special sensors for greenhouses will be further subdivided,and soil and plant information sensors will continue to become a research hotspot. Greenhouse sensors will generally continue to develop in the direction of smaller size,higher accuracy,non-contact,and real-time detection,and the trend of sensor information fusion will become more obvious. Sensors and IoT technologies will play an increasingly important role in the development of smart greenhouses.
