It is a project about participating in the Seoul IoT Hackathon 2018.
In South Korea, there are lines where placing things is prohibited for safety reasons in underground shopping malls or factories. Because, for example, a firewall may not work properly in the event of a fire. This project is a system that detects whether an object is placed on such a prohibition line and notifies the administrator through LoRa. This system can also measure fine dust concentration, gas, and motion information.
See the presentation from the link below (in Korean). It was a hackathon, and we had little time to prepare for the presentation. Please understand that the presentation has poor quality 😅.
I used OV7670_control, lcd_fonts, lcd_ili9341, lcd_spi, and system_control files from other source codes under the GNU license. Unfortunately, I don't remember from which repository. Please tell me if you know.
