ANAVI Technology launched several open source hardware boards for the Raspberry Pi and ESP8266 maker communities in the past, starting with RabbitMax Flex home automation HAT for Raspberry Pi, and several others including ANAVI Light Controller ESP8266 board to control LED strips.
All boards are designed with KiCad opensource EDA software, and I’ve tested several already such as ANAVI Infrared pHAT or ANAVI Light Controller, and found documentation to be very good and easy to follow. The company has now launched another ESP8266 board with ANAVI Thermometer that allows you to monitor temperature and humidity, effectively acting as a thermostat for home automation.
- SoC – Espressif Systems ESP8266 Tensilica L106 32-bit processor
- Connectivity – WiFi 802.11 b/g/n
- Display – Mini OLED display
- Build-in sensor – AM2302 (DHT22) temperature and humidity sensor
- Terminal block for DS18B20 waterproof temperature sensor
- UART pins
- 3x slots for I2C sensors
- Misc – Button
- Dimensions – 75 mm x 40 mm
- Certification – Open Source Hardware Association (OSHWA) BG000017
The board can be programmed or controlled with the Arduino IDE, PlatformIO, Home Assistant, MQTT, and any modern web browser.
Beside supports for the OLED display, and the two temperature sensors listed above, software has been written to support the following I2C sensors:
- BH1750 I2Csensor for light
- BMP180 I2Csensor for temperature and barometric pressure
- APDS-9960 I2C sensor for RGB color and gesture detection
Any other I2C sensor would also work, but you’d have to take care of software integration yourself. The key selling point of ANAVI Thermometer is that it is designed to be easy to use since it does not require any soldering, nor breadboard and accompanying jumper cables mess, and proper documentation & Arduino code sample will be made available. Video tutorials will also be uploaded to YouTube if the crowdfunding campaign raises more than $2,500.
As with all other ANAVI board, ANAVI Thermometer has been launched on Crowd Supply where you can pledge $25 for the board only, but other kits are also offered with the OLED display, an enclosure, and various sensors from the $39 starter kit to the $59 developer kit. Shipping is free, and delivery is expected for April 25, 2019.
