We are Taipei City Sanyu Elementary School - [Sanyu on Attack] - Cyberfair project team.
According to the network data, the healthy temperature suitable to human body is 18℃~25℃. The temperature of 37℃ is the most dangerous to food for the pathogenic bacteria reproduce the fastest in this temperature range.
According to the network data, the healthy humidity suitable to human body is 40%-70%RH. The humidity of 70%~90%RH is the most dangerous to food where the food may easily get spoiled or moldy.
The interior of the market is a semi-closed space and contains raw and fresh food materials as well as cooked food. Therefore, it is necessary to regularly detect the dangerous gases in the air (e.g., carbon monoxide/natural gas, etc.)
RESEARCH FRAMEWORK AND PLAN.
We first selected the places like Shidong Market, Sanyu Temple, Zhi Shan Yan and Tianhe Park and finally selected Shidong Market by way of voting
The teachers mentioned that a mind map can guide us to make the webpages and research topics without getting lost.
The air quality can be found out by utilizing the concept of IoT and Arduino in combination with the gas detectors, thus increasing the comfort and safety of shopping.
These are the gas detection equipment assembled by the teachers and us with a total number of two.
Built in with the DHT11 temperature and humidity sensor and MQ-135 gas detector, this equipment has the functions to detect the temperature, humidity, natural gas, alcohol, ammonia gas, etc.
