What is it?

ANAVI Thermometer is an open source hardware, Wi-Fi development board for measuring temperature, powered by an ESP8266 processor.

It comes with a built-in DHT22/AM2302 temperature and humidity sensor and has slots for a mini OLED display, waterproof DS18B20 temperature sensor, and empty slots for up to three additional I2C sensor modules.

All these features make ANAVI Thermometer appropriate for developers, makers, students and open source enthusiasts interested in home automation.

Why did you make it?

There are literally hundreds of project and development boards for logging temperature on the market. ANAVI Thermometer is not like them!

ANAVI Thermometer supports a huge variety of temperature sensors, and doesn’t require a breadboard or soldering iron to get started.

Also unlike the rest, ANAVI Thermometer combines open source hardware with free and open source software. It has been certified by the Open Source Hardware Association under UID BG000017.

To design ANAVI Thermometer and its acrylic enclosure were used free and open source software tools KiCAD and OpenSCAD. Source code and schematics are available at GitHub.

What makes it special?

ANAVI Thermometer is fun and easy to use! You don’t need to be a tech whiz to use it!

You can assemble it without any tools, and only a screwdriver is needed, if you are adding a waterproof temperature sensor.

Whether you’re a newbie to temperature sensing or a skilled engineer,ANAVI Thermometer is a great choice for most projects.

Getting started is very easy - just plug a standard USB charger into ANAVI Thermometer micro USB connector.

ANAVI Thermometer is useful for:

• Monitoring indoor ambient temperature and humidity for home automation

• Monitoring temperature in liquids, for example a fish tank

• Logging data in open source software platforms like Home Assistant, OpenHAB, Domoticz, etc.

• Rapid Internet of Things prototyping and software development

• Learning embedded software development by saving you the hassle of breadboards and jumper cables

ANAVI Thermometer can also serve as a convenient development board for home automation that’s suitable for anyone interested in Internet of Things, coding, and open source.
