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.
- 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
- Dimensions – 75 mm x 40 mm
- Certifications – Open Source Hardware Association (OSHWA) BG000018
MQ-135 sensor can be purchased as part of the some of the kits, but if you’d like to get your own sensors, any of the following should work:
- MQ-135 for air quality
- MQ2 for methane, butane, LPG, smoke
- MQ-3 for alcohol, ethanol, smoke
- MQ-7 for carbon monoxide
- MQ-9 for carbon monoxide and flammable gasses
