Easy Temperature Sensing for Home Automation

ANAVI Thermometer is an open source hardware, Wi-Fi development board for measuring temperature that’s 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.

Certified Open Source

ANAVI Thermometer is an entirely open source project that combines open source hardware with free and open source software. It has been certified by the Open Source Hardware Association under UID BG000017.

Measure air, humidity and water temperatures with ANAVI Thermometer

The free and open source software tools KiCAD and OpenSCAD were used to design ANAVI Thermometer and its acrylic enclosure. Source code and schematics are available at GitHub. All units will be manufactured in Plovdiv, Bulgaria.

Fun For All Skill Levels

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.

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.

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

Unlike the rest, ANAVI Thermometer is entirely open source, supports a huge variety of temperature sensors, and doesn’t require a breadboard or soldering iron to get started.

Manufacturing Plan

To ensure consistently high quality, ANAVI Thermometer has a green solder mask and a gold surface finish. All printed circuit boards (PCBs) for ANAVI Thermometer will be manufactured and assembled at a local factory in Plovdiv, Bulgaria, EU. The fabrication process includes a procedure called panelization which groups together a number of PCBs on a larger board called a "panel". After that, components will be mounted on each board.

All boards will be carefully manually flashed with open source software (already available at GitHub), tested, packaged, and shipped according to the schedule for each pledge.

Shipping & Fulfillment

This crowdfunding campaign offers ANAVI Thermometer with free worldwide shipping via the registered airmail service of the Bulgarian Post. All orders will be shipped from Plovdiv, Bulgaria. Your pledge will be packaged in an individual cardboard box and padded envelope for extra safety during transport. A tracking number will be provided as soon as the order has been shipped.

Risks & Challenges

ANAVI Thermometer is a certified open source hardware product. We have already manufactured a small-run batch to ensure that everything works correctly. Although this significantly reduces any risks, mass production still depends on factories and suppliers. Availability of parts can also be an issue. In order to provide ANAVI Thermometer at the best price, we are working with reliable suppliers and a trusted local factory in Plovdiv, Bulgaria.

We have experience successfully delivering projects on time, and even ahead of schedule, from our previous crowdfunding campaign for Infrared pHAT, Light pHAT, Light Controller, etc. We are confident that we can again arrange successful mass production on time. However, if any delays occur, backers will be notified promptly through regular updates.
