Arduino uno esp8266 sending sensor database dashboard

Projects General Guidance

Hello,

I am new to this forum and would like to seek assistance with a project that I am working on. I am using an Arduino Uno, an ESP8266 WiFi module, and 3 temperature sensors (DS18B20) to collect data. My goal is to create a database to store the sensor data and then display it in a visual dashboard. However, as a newbie, I am encountering difficulties with this task and I have not been able to find a tutorial to help me.

Currently, I am using Swamp Server to create the database and Qlikview for the dashboard, but I am open to changing my tools if there are better options available with tutorials. I would appreciate any kind of help with my project.

This tutoriel is the closest i got but he's using a motion sensor and without a dashboard

Tell me if i should provide any informations

There are tons of boards matching that description but with differing in many ways. You have to provide a link to the used hardware to specify what exact board you're using.

As the ESP8266 runs on 3.3V but the UNO on 5V they are not on compatible voltage levels. You need a level converter to connect the two boards. I know that there are many tutorials that simply connect them but that's outside the specification and may be unreliable and/or even damage your WiFi board.

For your choice of sensors you don't need the UNO, you can connect them directly to the ESP8266 and use a sketch on it to send the data. That eliminates the problem of connecting the two boards.
