bme280-pi

Use the BME280 temperature, pressure and humidity sensor on the Raspberry Pi and display the output in the terminal.

Inspiration taken from this guide on Raspberry Pi Spy, but adapted to display only the temperature, pressure and humidity readings in the terminal.

The script called bme280-mdot-beebotte.py also sends sensor readings to Beebotte every 15 minutes so you can log the readings over time.

Installation

Clone this repository:

git clone https://github.com/raspberrycoulis/bme280-pi.git

Then ensure the BME280 is connected up correctly:

3.3V to VIN
GND to GND
SDA to SDA
SCL to SCL

Also need to ensure that I2C and SPI are enabled via sudo raspi-config and enabling I2C and SPI via the Interface menu. For good measure, it is also worth installing i2c-tools via sudo apt-get update && sudo apt-get install i2c-tools. Verify that your Raspberry Pi can see the BME280 by running sudo i2cdetect -y 1 at the command prompt.

Install Beebotte

If you plan on using the Beebotte side of things, you’ll need to install the Beebotte client via:

pip install beebotte

Then you will need to create a channel and use the token in the bme280-mdot-beebotte.py code.

Running

Assuming you are in the bme280-pi directory, simply run:

./bme280-pi.py

This will display the current temperature, pressure and humidity in the terminal, updating every 0.5 seconds. Exit via CTRL+C.

To do

I'm experimenting with Pushover notifications to alert you when the temperature rises above a set threshold. This works, but not with everything else right now - i.e. the Micro Dot pHAT, Beebotte and Pushover. I'm still trying to figure this out.
