Project description
Step 1: Introduction Today I will present in detail the last realized project, which is quite complex in terms of functionality, number of sensors used, Arduino boards, used data buses. The project consists of two modules. Physically each module consists of a separate Arduino Mega 2560, Ethernet shield W5100 (R3 compatible) and the sensors it uses. Each module communicates with the web interface on the Internet by HTTP POST requests, by which the web server sells data or request some data, for example via POST request (module 2 only). The web interface is completed with a login system, while…
