Displays a graph of the temperature, humidity, and pressure from a BME280 sensor.

• Adafruit Circuit Python BME280 library
• Adafruit BME280 I2C Sensor (Product ID: 2652)
• Python 3 (Adafruit libraries are not Python 2.x compatible)

It produces the following charts:

1. Temperature
2. Humidity
3. Pressure
4. Altitude

Allow the netdata user to access the I2C interface.

sudo usermod -a -G i2c netdata

Edit the python.d/bme280.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata     # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/bme280.conf

Raspberry Pi Instructions:

Hardware install: Connect the BME280 to the Raspberry Pi I2C pins

Raspberry Pi 3B/4 Pins:

• Board 3.3V (pin 1) to sensor VIN (pin 1)
• Board SDA (pin 3) to sensor SDA (pin 2)
• Board GND (pin 6) to sensor GND (pin 3)
• Board SCL (pin 5) to sensor SCL (pin 4)

You may also need to add two I2C pullup resistors if your board does not already have them. The Raspberry Pi does have internal pullup resistors but it doesn't hurt to add them anyway. You can use 2.2K - 10K but we will just use 10K. The resistors go from VDD to SCL and SDA each.

Software install:

• sudo pip3 install adafruit-circuitpython-bme280
• sudo usermod -a -G i2c netdata
• edit /etc/netdata/netdata.conf
• find [plugin:python.d]
• add command options = -ppython3
• save the file.
• restart the netdata service.
• check the dashboard.
