When we think about connected devices, the first thing that usually comes to mind is modern designs with screens, full connectivity and integration into the connected home. A mix of factors that They usually require a checkout and spend a good amount of money.
But there are people who like to spoil and try all kinds of things. And this is what the user @mrcatacroquer has done, who has bought an old oven at a knockdown price and has turned it into a Smart model which you control remotely from your mobile phone.
DIY and craft
This user has obtained an old oven that is used to make ceramics for only 50 euros and with some skill AND the appropriate technical knowledge, he has turned it into an oven connected to the Internet, transforming it into a ovenOmatic with remote control via @telegrampossibility of establishing temperature curves and telemetry management with Google.
All runs inside a module ESP32a low-cost, low-power microcontroller used in a variety of applications, from IoT (Internet of Things) projects to hardware developments and electronics projects.
A module that incorporates WiFi and Bluetooth modules, a 32-bit dual-core processor, making it ideal for projects that require wireless connectivity. In addition, it has different input/output pins that allow connection with sensors, actuators and other devices.
It has a large community of developers and is compatible with Arduino development environmentwhich makes programming and project creation easier… and this is one of its advantages.
To get the most out of it, it is programmed with Arduino IDE software and in this case It is controlled with a Telegram bot (@oven.o.matic) that allows you to turn the oven on and off remotely, as well as check how cooking is going
Furthermore, and to avoid problems during firing and so that the ceramic is not there with a sudden increase in temperature, the system takes care of send data related to temperature current to a Google spreadsheet where you can check if the temperature (red line) is being adjusted to the programmed curve (blue line).
With this process he has managed to create ceramic mugs in an oven that, according to the user himself, “consumes 3KW and takes about 7 hours of cooking.” This very low consumption has been possible thanks to the temperature curves that make them rise progressively and gradually, has managed to “turn on and off many times making it less expensive.”
