![]() 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’ll need a slightly more complicated Python script:Ĭalibration_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. Way to go! Our hardware has produced a sensible output, so we know all’s 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:īme280.load_calibration_params(bus, 0x76) Let’s kick off with a really rough n’ ready program, just to check our hardware is behaving properly. Now it’s time to get our programming head on as we start to write our Python Program. Want to use Python 3? You’ll need to use pip3: ![]() …and lo and behold, there it is at address 0x76! Phew. ![]() Now we’ve installed the I2C tools, we can check 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: And those pesky little kernel modules should now be well and truly loaded. Now reboot and check dmesg or lsmod again. Now hit the which takes us back to the main menu. We now need to move down to ‘Interfacing Options’ and : Then use the arrow key to move down to ‘Advanced Options’ and hit : But, if you don’t see any I2C kernel modules listed, here’s how to enable them: In this pic they’re all present and correct. So simply run dmesg or lsmod from the command line in a terminal: The first thing we need to do is make sure the I2C kernel driver is enabled on our Raspberry Pi. So using the spacer to move the sensor away from this heat source should pretty much mitigate any distorted readings. And even doing zip, the processor was pushing a tropical 45☌. In fact, we used a quick shell script to find the processor temperature. As you regular Pi guys out there know, the processor can get toasty even when it isn’t doing all that much: We’d normally use the MD01 spacer (in this case it’s the MD03) to make sure our sensor isn’t reading the temperature directly above the Broadcom processor (woops). Start by fitting the BR01 Rasperry Pi bridge onto the GPIO pins furthest away from the USB sockets on your Pi: OK, fingers nice and warm? Let’s do this… We’ll be using Richard Hull’s Python module for this little project (there’s also an Adafruit module you could use). Since XinaBox modules use I2C to interface together, and the BME280 is an I2C device, we can use existing Python BME280 libraries to drive the sensor from our Raspberry Pi. The SW01 module sports a magical Bosch BME280 digital sensor that gives accurate readings for temperature, humidity and air pressure. These clever little square modules are fab for clipping together super-fast prototypes for all sorts of circuit stuff. If you’re new to the wonders of XinaBox, you’re in for a treat. With this in mind, we thought we’d show you how to be the first to know with this nifty little weather station using our old friend Raspberry Pi – plus a couple of cheap Xinabox parts and ten minutes of your precious time. But what we call a heatwave here in blighty has got us all clambering for news of what Nature has in store for us on the weather front. ![]() After all, temperatures soared just above tepid and there wasn’t as much as a drop of snow. Truth be told, it’s been a somewhat freakish summer. Next will cover hardware part on making the display mirror.Forget Brexit – the hot topic this year in the UK is…you guessed it, the weather. In such case try clearing npm cache and try again npm cache cleanĭo let me know any issues found during installation. npm version mistmatch or error in installing npm. In such case increase the github post buffer as shown below: git config -global http.postBuffer 524288000/1048576000Ģ. Sometime you may face issue in cloning like “The remote end hung up unexpectedly while git cloning”. Issue in cloning the MagicMirror repository.To test the edited config file run the following command as shown in the screenshot below Refer the screenshot below to update the configuration. To configure the Modules update config.js file. Clone the repository and check out the master branch:.Download and install the latest Node.js version:.In this post we will only cover software installation part. Raspberry Pi 2/3/4 with Full Raspbian OS installed. ![]() For this project you will need Raspberry pi installed with full version of Raspbian OS. In this post I will explain how to install the software and configure it based on your preferences. This can be installed in any raspberry pi 2/3/4. This is one of the very popular raspberry pi project. These Raspberry Pi smart mirrors can tell you the time, date, weather, and more. Magic Mirror is an open source modular smart mirror platform. ![]()
