Getting Started with ANAVI Gas Detector Starter Kit and Home Assistant

ANAVI ESP8266 Gas Detector Display

ANAVI Gas Detector is an ESP8266 based board designed for MQ gas sensors supported by Arduino. This allows you to easily monitor air quality, or more accurately air conductivity using MQ-135 sensor as part of the starter kit either visually on the OLED display, or through your smartphone or computer using MQTT via automation platform such as Home Assistant. Leon Anavi sent me an ANAVI Gas Detector Starter Kit to have a look, and I’ll report my experience with the kit using it standalone, and through Home Assistant. Starter Kit Unboxing The kit contains the open-source hardware, ESP8266 based ANAVI Gas Detector board, a plastic stand, an OLED display, a USB to serial adapter, a gas sensor, and a few KiCad and ANAVI stickers. The board itself comes with an ESP8266MOD module, features a micro USB port for power, a reset button, four LEDs, a UART console, a 4-pin GPIO header, three I2C headers for sensors, a 4-pin connector for …

ANAVI Gas Detector ESP8266 Board Monitors Air Quality, Toxic Gases (Crowdfunding)

ANAVI Gas Detector

Leon ANAVI is a software engineer with an interest in open-source hardware, and he had previously launched several ANAVI boards for home automation based on Espressif ESP8266 or for Raspberry Pi boards including ANAVI thermometer, ANAVI light controller, and ANAVI Infrared pHAT among others. Leon has now introduced a new board on Crowd Supply: ANAVI gas detector. The board is powered by ESP8266 WiSoC providing WiFI connectivity, and supports MQ gas sensor modules such as MQ-135, MQ-2, or MQ-3 in order to monitor air quality and detect gas leaks. ANAVI gas detector board specifications: Wireless Module – Based on ESP8266 Tensilica L106 32-bit processor with Wi-Fi 4 802.11 b/g/n connectivity Display – Optional Mini OLED display Gas sensor support – MQ-135 for air quality or any other 5V MQ analog gas sensor Expansion – 3x slots for I²C sensors Debugging / Programming – UART pins for flashing custom firmware Misc – Button Power Supply – 5V via micro USB port …

Getting Started with Temperature & Humidity Sensors on ESP8266 using ANAVI Thermometer

ANAVI Thermometer Air / Humidity / Water

ANAVI Thermometer was launched on CrowdSupply in January.  It is an ESP8266 WiFi board with a built-in DHT22 temperature and humidity sensor, support for external DS18B20 waterproof temperature sensor, as well as other sensors thanks to three I2C sensors. I received the ANAVI Thermometer starter kit last month, and I’ve only found time to play with it in the last few days. I’ll start with a unboxing, assembly guide, before showing it action, and I’ll try to make it interface with Home Assistant over MQTT. ANAVI Thermometer Starter Kit Unboxing The kit comes with ANAVI Thermometer board, a plastic stand, a USB to TTL debug board, an I2C OLED display, a few nuts and bolts, and a couple of KiCad and ANAVI stickers. Leon ANAVI also added a traffic light board and LEDs, but it’s not normally part of the kit 🙂 ANAVI Thermometer board include an ESP8266 module, AM2302 (wired DHT 22) temperature and humidity sensor, a terminal block …

Shelly H&T is a Battery Powered ESP8266 WiFi Temperature & Humidity Sensor

Battery Powered ESP8266 Temperature Humidity Sensor

WiFi and long battery life do not usually go hand-in-hand, but as we’ve seen recently, companies have managed to design battery powered WiFi cameras that are said to last up to a year on a charge. So for simpler WiFi devices it should be feasible to last over a year, and that’s what “Shelly H&T” – an ESP8266 based battery-powered WiFi temperature and humidity sensor has apparently achieved, with claims of up to 16 months battery life. Shelly H&T specifications: Connectivity – 802.11 b/g/n WiFi (Wifi 4) Sensor – Temperature & humidity  Battery – 1x CR123A battery good for up to 16 months Dimensions – 35 mm Ø sphere with flat top/bottom  The firmware supports MQTT, and a Rest API, and works with Alexa, Google Home, and home automation suites like OpenHAB, Home Assistant, or Domoticz. The sensor is “open source ready”, meaning you’ll be able to flash your own firmware through the serial interface as shown below. The device …

ESP8266 based ANAVI Light Controller can be Programmed with Home Assistant or the Arduino IDE (Crowdfunding)

ANAVI Technology previously launched a Light pHAT allowing for RGB Light strip connection to Raspberry Pi boards, and during my review of ANAVI Light pHAT with Raspberry Pi 2, it did the job, but if that’s all you want to do, the  Raspberry Pi board is clearly oversized & overpowered for the job. So Leon ANAVI got back to the drawing board and designed a similar open source hardware board – called ANAVI Light Controller – with an built-in ESP8266 module that removes the need for a fully fledged Linux board. ANAVI Light Controller specifications: Wireless Module – ESP8266MOD module based on ESP8266 Tensilica L106 32-bit processor Connectivity – WiFi 802.11 b/g/n Expansion Terminal block for 12 V RGB LED strip 3x I2C headers for sensors Debugging – UART header Misc – Button Power Supply – 12 V via power barrel jack Dimensions – 75 mm x 40 mm Certification – Open Source Hardware Association (OSHWA) BG000005 The board can …

FOSDEM 2018 Open Source Developers Meeting Schedule

FOSDEM (Free and Open Source Software Developers’ European Meeting) occurs every year on the first week-end of February, where developers meet for two days discussing about open source software projects. FOSDEM 2018 will take place on February 3-4 this year with  652 speakers, 684 events, and 57 tracks, an increase over  last year 608 speakers, 653 events, and 54 tracks. There will be 8 main tracks namely: Community, History, Miscellaneous, Performance, Python, Security and Encryption, Space, and Global Diversity CFP Day. There will also be 33 developer rooms, and since the full schedule is now available, I’ll make a virtual schedule mostly based on sessions from the Embedded, mobile, and automotive, Hardware Enablement, and Internet of Things devrooms. Saturday 3, 2018 09:50 – 10:15 – Turning On the Lights with Home Assistant and MQTT by Leon Anavi In this presentation you will learn the exact steps for using MQTT JSON Light component of the open source home automation platform Home …

Getting Started with ANAVI Light pHat Starter Kit with RGB LED Strip, Light Sensor

ANAVI Light pHAT is an expansion board best suited for Raspberry Pi Zero (W/WH) boards, but also working with any other Raspberry Pi boards with a 40-pin header, that can control a 12V RGB LED strip and sensors. The project’s crowdfunding has just been successfully completed on CrowdSupply with 82 pledges, but you can still pre-order the board or kits for $25 and up. The developer – Leon ANAVI – had sent me a starter kit a little while ago, and this week-end I had time to test the basic functionalities of the board. The package includes the pHAT board itself, a one meter RGB LED strip, an I2C sensor, and some stickers. The sensor is based on BH1750 ambient light intensity sensor. The light pHAT boards include a 4-pin 12V/RGB blue terminal, EEPROM, three I2C connecter, a 3.3V UART connector to access the serial console for debugging / running commands, and a 3-pin PIR sensor header on the left. …
