Also, make sure that you use the absolute path to your program (as shown) and not its relative path. Replace 'filename.py' with the name of your script.
#STRANGER THINGS SEASON 2 EPISODE 1 MINUTES CODE#
In the rc.local file, enter the following line of code before the "exit 0" line: SSH into your Pi and open the rc.local file:Ģ. There are a couple of ways to go about this, both are relatively easy for a noob.ġ. You can’t help feeling the future looks bright! More are being added all the time, so I’m excited by the prospect of being able to build and deploy almost any kind of IoT or autonomous embedded system that I can imagine, pretty much at the drop of a hat. There are over 80 x-chips covering a host of different processor, sensor and communications functions. This is ideal for super-quick prototyping or makeshift measurement instruments that you can take apart and re-use for other purposes when you’re done. Then you can clip these functions together in seconds and get straight to programming. You don’t even need to know much about electronics – you just need to know the functionality you want. The XinaBox x-chips make it incredibly fast to try out any ideas you may have. The log file ends up looking something like this: I have used only a 5-second interval between each loop in order to get some quick data output, but in a real-world logging situation, you would probably want to have an interval of something more like 5 to 15 minutes between log entries. Instead, our output is appended to a file on each loop: When we save and run this, not much happens in the terminal. Layout = ' %'ĭata = bme280.sample(bus, address, calibration_params)į.write(layout.format(counter, data.timestamp, data.temperature, data.pressure, data.humidity) + "\n") For this we are going to need a slightly more complicated Python script: import timeĬalibration_params = bme280.load_calibration_params(bus, address) Now we can go on and do something useful, like logging our readings over time into a file. Our hardware has produced a sensible output, so we know it’s all working as it should. Open a terminal and run the script from the command line: Open the text editor or use Geany to enter a test script: import smbus2īme280.load_calibration_params(bus, 0x76)

We will start with a really rough n’ ready program, just to make sure our hardware is behaving as expected.
#STRANGER THINGS SEASON 2 EPISODE 1 MINUTES INSTALL#
If you want to use Python 3, then you will need to use pip3: $ sudo pip3 install RPi.bme280 ProgrammingĪt this point, we are ready to begin writing our Python Program. Now we can install our Python module: $ sudo pip install RPi.bme280 With the I2C tools installed, we can check that our weather sensor is visible on the bus: The next thing we need to do is install some tools and an essential pre-requisite Python library: If we reboot and check dmesg or lsmod again, we should see the kernel modules are now loaded. Hit the which takes us back to the main menu. We then need to move down to ‘Interfacing Options’ and : Then use the down arrow key to move down to ‘Advanced Options’ and hit : In your terminal type: $ sudo raspi-config If we find, unlike in the picture above, that we have no listed I2C kernel modules then we will need to enable them. We can do this by running dmesg or lsmod from the command line in a terminal:
#STRANGER THINGS SEASON 2 EPISODE 1 MINUTES DRIVER#
The first thing we need to do is make sure the I2C kernel driver is enabled on our Raspberry Pi. Moving the sensor away from this heat source, using the spacer, should (mostly) mitigate any distorted readings. I used a quick shell script to get the processor temperatures and even doing nothing, the processor is at 45 degrees C.

As regular Pi users will know, the processor can get quite warm, even when it isn’t doing all that much: We are using the MD01 spacer (or in my case, the MD03) to make sure our sensor is not reading the temperature directly above the Broadcom processor. The BR01 Rasperry Pi bridge fits onto the GPIO pins furthest away from the USB sockets on your Pi: For this experiment, I will be using Richard Hull’s Python module, though there is also an Adafruit module you could use. XinaBox modules use I2C to interface with each other and the BME280 is an I2C device, so we can use existing Python BME280 libraries to drive the sensor from our Raspberry Pi. The SW01 module sports a Bosch BME280 digital sensor that will give us accurate readings for temperature, humidity and air pressure.
