In order to measure and monitor the yield of solar greenhouse crops, a solar greenhouse yield monitoring system was developed. The system was consisted of three parts: a pressure sensor terminal, wireless data transmission network and software of monitoring yield. The wireless data transmission network was built and the communication among wireless network, pressure sensor output terminals and PC monitoring software was realized. The yield related information was got and the data was stored in the database to facilitate statistical analysis. The results of the analysis could help to adjust the greenhouse environment, crop growth environment and the greenhouse management. Meanwhile, the RFID tags were added on the measured vegetables to achieve traceability of the vegetable origin and other information. Experimental results showed that the system design was reasonable, reliable, easy to operate and convenient to use. The system could improve the efficiency of the greenhouse yield measurement, and it was able to effectively enhance the degree of automation in greenhouse yield. Meanwhile, this system facilitated the adjustment of greenhouse management.
