Airthings Wave is a smart radon detector with quick and accurate results on your smartphone. On the monitor you'll see NOOBS initializing. The RadonFTLab was launched in 2015 as a division of Radon research & business of FTLAB. This guide will show how to read sensor data from the Airthings Wave using a Raspberry Pi 3 Model B over Bluetooth Low Energy (BLE). Open up the terminal and run: Next, we need to update the software packages. Name the photos incrementally so you know what order they were taken in—for example. Using the latest in smart technology, the Radon Eye RD200 boasts 20 times the sensitivity compared to other radon detectors. Radon Eye RD200. This guide has been tested with Raspberry Pi 3 Model B, Raspbian Stretch (November 2017), bluepy 1.1.4 and Python 2.7.13. To get around this, I run it continuously on a Raspberry Pi that connects regularly to the radon detector. The first step is to setup the Raspberry Pi with Raspbian. There are lots of webcam and motion detector solutions out on the market today, but making one in a DIY fashion gives us a lot more control over how it operates. No matter if you had success or if you got stuck along the way, we’d like to hear from you! The detector can identify rogue towers and triangulate their location. What’s the Best Raspberry Pi Camera For Your Project? © 2020, O’Reilly Media, Inc. All trademarks and registered trademarks appearing on oreilly.com are the property of their respective owners. This means that these scripts only can read the Wave data while your phone is not connected to the Wave, and vice versa. Question Must be larger than zero. EZVIZ Mini HD 720p WiFi Home Security Camera, How to Make an Old-school Neon Street Sign. That's it for this tutorial! The large can will serve as the ionization chamber (in the radon detector). If you have many devices, you may run the command with a filter to find your BLE address: pi@raspberrypi:~ $ sudo python find_wave.py | grep [SN]. Once the flashing is completed, insert your SD card into the Pi and power it up.

This can be done by creating a file named ssh in the boot partition of the SD card. where you replace [SN] with the serial number on the backside of your Wave. We wrote in detail about our Raspberry Pi geiger counter project in another post, now this guide focuses on the basics necessary to build your own. Additionally, you can request new features, open issues or even contribute to the project by creating pull requests. i have a commercial unit at home but i'd like to automate it to at least keep track of the levels when i'm not downstairs to check them. There’s more you can do! Congrats! Make sure you install the latest firmware. potentially also to control my radon fan when levels get high. This is the standard type. To do this we need a radiation detector board, sometimes known as a Geiger counter or Geiger-Muller counter, named after those who invented it. A true micro-controller is e.g. We build and feature projects that monitor the environment around them quite frequently at balena, but this is the first time we’ve started to take a look at monitoring radiation levels. The large can used could be a coffee can, baby formula can, cookie tin, or some other large can that is about 4 inches in diameter and 5 inches tall. Once it's ready, it will prompt you to select an operating system. stream_port: This is the default port that the webcam server will run on. To verify this, look for “Powered: yes” after issuing the following command: Download the two Python scripts by doing the following: wget www.airthings.com/tech/find_wave.py wget www.airthings.com/tech/read_wave.py. In this project I used a Raspberry Pi 3 which was connected to a monitor, mouse, and keyboard so that setting up the webcam would be relatively simple. The radon level history stored on the Wave itself cannot be accessed with this program. The SD card must be formatted in the FAT (File Allocation Table) format. BUT WAIT! In a previous post, we showed you how you could use a Raspberry Pi 3 Model B to read sensor data from the Airthings Wave over Bluetooth Low Energy (BLE). In this example we’ll just use the motion event to make a popup appear on the Raspberry Pi’s monitor. In order to enable this, we'll have to do a bit of configuring. The available sensor data are temperature, humidity, running average 24-hour radon concentration and running long-term average radon concentration. To add two LED counters in a circular fashion like we did, you’ll need the following additional electronic components: Unless you already have a preferred supplier, I recommend Ebay for obtaining small quantities of a wide variety of LEDs and other electronic components. Did you make this project? In this tutorial we will be creating a motion detector with a raspberry pi and a normal USB webcam.
