ESP32 Forum

Hello!

I'm working on a hobby project and i need to create a controller for it. It's a ventilation system with 2x big 230v EC fans which can be controlled with 0-10 V control.
I need:
4x temperature sensors
1x co2 sensor
2x humidity sensors.
+ 2x 0-10 V controller for the 2x ec Fans.

-I would like to be able to control the fans based on the sensors value.
-I would want to be able to control the esp32 through wifi.

I never did any esp32 projects before, but i'm good in programming.

I need help with the hardware please. Can someone guide me which board/kit/sensors i need to buy to be able to do these above?
I dont mind if its not the cheapest if its easier to work with.

Any help is highly appreciated. Thank you.

Use an ESP32 DevKit for control and Wi-Fi.

Add an SCD30 for CO₂. Use two SHT31 boards for humidity.

Use four DS18B20 sensors for temperature.

Control the fans with a DFRobot 0–10 V DAC board. This setup is simple and works well.

I need:
4x temperature sensors
1x co2 sensor
2x humidity sensors.
+ 2x 0-10 V controller for the 2x ec Fans.

All the components are here.
