As you know, in August 2019 I created ANAVI Gas Detector - an open source Wi-Fi dev board for monitoring indoor air quality and detecting dangerous gases. Thanks to your support during the crowdfunding campaign here at Crowd Supply it became a reality. If you take a closer look at the development boards of ANAVI Gas Detector and ANAVI Fume Extractor you will notice a lot of similarities. If you, like me, also like soldering, hurry and place an order during the crowdfunding period to be among the first owners of ANAVI Fume Extractor. Read the full update.
Backer Jan K. used the Anavi Gas Detector with his home automation system to provide air quality alerts live and over the network. Read the full update to see how he did it. Read the full update.
As you know the default firmware for ANAVI Gas Detector is available in a free and open source Arduino sketch on GitHub. However, if you just need to get the latest stable version of the firmware, the fastest and easiest way is to download a pre-compiled binary and flash it with esptool. Read the full update.
Friday last week, 8 November, all ANAVI Gas Detectors for your orders were delivered to Crowd Supply. Now, approximately 2 weeks ahead of schedule, Crowd Supply team will start shipping them to you! Read the full update.
Good news everyone, the manufacturing of the first batch of ANAVI Gas Detector has been done! We are expecting another batch at the end of next week. In the meantime, the units from the first batch will be flashed with the default open source firmware, tested and packaged. Read the full update.
Did you make something amazing with your Anavi gear? Let us know by submitting a Field Report and you can get a Crowd Supply credit and win prizes! Read the full update to find out how. Read the full update.
In the previous update we have covered the exact steps to assemble a kit with ANAVI Gas Detector. The next step is to connect it to your Wi-Fi network. Read the full update.
I have recently shared ANAVI Gas Detector assembly guide which is available at my YouTube channel. The whole process takes about 10 minutes. You will need a screwdriver. Please find below the exact steps (and images) with additional details. Read the full update.
The crowdfunding campaign of ANAVI Gas Detector has ended successfully and we are proceeding to manufacturing. To celebrate the successful campaign I would like to share with you a funny video of how ANAVI Gas Detector can be used in a do-it-yourself breathalyzer, with MQ-3 gas sensor module and a lot of LEGO bricks. Read the full update.
All ANAVI Gas Detector kits include a MQ-135 analog gas sensor module for detecting air quality. According to the data sheet of MQ-135, the sensitivity characteristics of the sensor depend on temperature and humidity. Because of this, the Advanced and Developer kits of ANAVI Gas Detector also include a HTU21D I2C temperature and humidity sensor module. For everyone's convenience, the default Arduino sketch for ANAVI Gas Detector supports both Celsius and Fahrenheit. Read the full update.
Earlier this month I sent a few units from the very first batch of ANAVI Gas Detector to friends and popular contributors in the open source community. Jean-Luc Aufranc from cnx-software.com was kind enough to test ANAVI Gas Detector and to publish a tutorial on how to use it with Home Assistant. Read the full update.
ANAVI Gas Detector is an entirely open source development board and it is easy to flash a custom firmware. In this video tutorial I will explain how to compile and upload an Arduino sketch to it through Arduino IDE. Read the full update.
Following the successful start of the ANAVI Gas Detector crowdfunding campaign, a lot of people asked me, "what is the power consumption and can it run on batteries?". Instead of just giving you the technical specifications from a datasheet, I prefer to share a short video with a couple of experiments. Read the full update.
Thanks to your support the crowd funding campaign of ANAVI Gas Detector is enjoying huge success! All stretch goals have been already achieved and as promised I am sharing with you new video tutorials. In this video you will learn all you need to know about MQ-135 gas sensor module for monitoring indoor air quality. Read the full update.
ANAVI Gas Detector is enjoying a fantastic start to the crowdfunding campaign! In just 10 days, the project is fully funded and we hit all stretch goals! As promised, awesome stickers promoting open source will be added to each package and we will start preparing video tutorials. Read the full update.
