DIY Wi-Fi sensor, no programming, no soldering required*

Software no-code/low-code platforms made it possible to create applications, writing only a few lines of code, and in some cases, ¡no code at all!. This reduces development effort and deployment time.

This project combines two ideas: no-code/low-code software platform and a quick, robust prototyping system that requires no soldering. In this spirit, it is possible to move from an idea, to a materialised device working in a real environment in a few hours.

Quick, robust hardware-software prototyping
The following application will be built as an example: a WiFi thermometer based on ESP32, DS18B20 temperature sensor, and local I2C indicator. All this enclosed in a waterproof, wall-mountable box and powered by 5V. This will be accomplished using the following projects:

- HARDWARE: Quick, Open Source, robust prototyping system: MISISTEMITA
- SOFTWARE: Tested TASMOTA and also ESPHome.

Discrete parts needed
Component Datasheet

- OLED 0.96 I2C Display
- DS18B20 waterproof temperature sensor
