| Summary: | 碩士 === 國立彰化師範大學 === 機電工程學系 === 107 === There are many food contamination issues in recent years. People very concern if they eat any heavy metal or pesticide pollution food into the body. Government authority prohibit some pesticide which hard to decay by time or heat. Government authority also define how to use pesticide and how long the fruits and vegetables can be harvested. According annual pesticide residues report which published by Taiwan Agricultural Chemicals and Toxic Substances Research Institute, Council of Agriculture, Executive Yuan says, 50% fruits and vegetables have pesticide residues and 2~10% over the tolerate criteria. The pesticide residues detection is very important for people to monitor the fruits and vegetables status.
Traditional pesticide residues inspect instruments are HPLC and GC/MS, the cost is high and time consumption. People will easy to test pesticide residues by home use detector. Combine with mobile device app and cloud server, test result could upload to mobile device app and share to everyone. People will choice the good food and push manufactures to avoid the pesticide contamination.
In this study, mobile device app and cloud server for pesticide residues testing result have been development. Testing result upload to mobile device app with testing time and location. The information of fruits and vegetables can be noted, such as name, manufacture (store), purchasing date and picture. The testing results and information be uploading to cloud server for people to check the pesticide residues status by different classification. It could be easy to get information by map with red dots (unqualified) and green dots (qualified). Hope the open pesticide residues information will help people feel safe in buying food, cooking food and eating food. Everyone can join the team and say no to unproven manufacturer.
