About This Project

In the first place created this project to learn more about an ESP and MicroPython. To have an actual useful project i decided to measure the soil moist of my living room plant as well as the temperature and the humidity.
An other reason why i decided to measure these parameters is to learn as much as possible.
There are several aspects represented in this project.

  1. ESP8266
  2. I2C (Temp/Hum Sensor)
  3. Analog (Soil moist Senosr)
  4. MQTT (Cayenne)
  5. MicroPython
  6. Did i miss something?

Description

If this project hits actual interest i will describe everything better.

What’s Connected

I used following Hardware:

  • NodeMCU-0.9 with ESP8266
  • HTU21D for temp and hum measurment
  • YL-69 for soil measurment
  • some LEDs for statusinformations

Fritzing Pic will follow
