Development and evaluation on a Wireless Multi- Gas- Sensors System for improving traceability and
There is increasing requirement to improve traceability and transparency of table grapes cold chain. Key traceability indicators including temperature, humidity and gas microenvironments (e.g., CO2, O2, and SO2) based on table grape cold chain management need to be monitored and controlled. This paper presents a Wireless Multi- Gas-Sensors System (WGS2) as an effective real time cold chain monitoring system, which consists of three units: the WMN applied 433MHz as the radio frequency to increase the transmission performance and form a wireless sensor network ; the WAN serves as the intermediary to connect the users and the sensor nodes to keep the sensor data without delay by the GPRS remote transmission module ; the signal processing unit contains embedded software which is used to drive the hardware to normal operation and shelf life prediction for table grapes. Then the study evaluates the WGS2 in a cold chain scenario and analyses the monitoring data. The results show that the WGS2 is effective in monitoring quality, and improving transparency and traceability of table grape cold chains. Its deployability and efficiency in implantation can enable the establishment of a more efficient, transparent and traceable table grape supply chain.
