Building a simple Weather Station

Intoduction

Up to now we have only used simlated sensors (the push button for digital signals and the potentiometer for analogue signals). In order to build a weather station we of course need real sensors, and we will use a SHT30 temperature and humidity sensor and the BMP180 to measure the barometric pressure. Every second these sensors will be read and the measurement results displayed on the OLED display.

All three devices use the I2C bus to communicate with the ESP32 CPU.

Here are the descriptions of the devices and their MicroPython software drivers

• SHT30
• BPM180
• OLED Display
