Super simple micropython project for exploring sensor loops on the ESP8266 and ESP32.

• esp-8266
• bme-280 - temperature + pressure + humidity sensor (or bmp-280 - inferior substitute, temperature+pressure only)

• 3.3V -> VCC
• GND -> GND
• D1 -> SCL
• D2 -> SDA
• D0 -> RST (both pins on esp-8266)
• VCC -> CSB -> SDO (all pins on bme-280)

BME-280 uses I2C to communicate. If you have 4-pin devince you will need to alter the address in the code to 0x76. If you have 6-pin device like me, wire a jumper between VCC and the two opposite pins (CSB and SDO) in order to configure for I2C address 0x77.

• Copy all files to esp-8266 using ampy ampy put *
• Use minicom -D /dev/ttyUSB0 -b 115200 -8 or similar to interact with shell
• Ctrl-C during the mainloop to break to console and avoid deep-sleep
• Ctrl-D from console to restart the sensor loop
• you must quit minicom to use ampy
