This project is launching soon.
Sensor Watch Pro is a board swap for the classic Casio F-91W and A158 wristwatches. We pair an iconic design from the golden age of digital watches with a modern, powerful microcontroller and state-of-the-art sensing. This yields a tiny board with powerful capabilities for sensing the world around you. It’s equipped with a temperature and infrared light sensor on board, as well as a 9-pin expansion port for adding additional sensors, like an accelerometer, on a tiny modular add-on board.
Sensor Watch Pro builds on the legacy of the highly successful Sensor Watch and Sensor Watch Lite campaigns. Sensor Watch Pro is fully compatible with Movement, the community firmware for Sensor Watch, which supports more than 80 watch faces with a simple, no-code approach to customization. You can build a firmware image with exactly the functions you want, upload it to the watch via drag-and-drop, and then wear a watch that’s uniquely yours that lasts for over a year on a single coin cell.
With nothing more than the Sensor Watch Pro board, you can do everything that Sensor Watch Lite can do: build a firmware image with sunset times and moon phases, a Mars clock, a dice roller, or a tarot deck. The addition of an RGB LED means your backlight can take on all the colors of the rainbow, and the IR receiver opens up new possibilities for data input and light sensing.
With the accelerometer add-on board, you can stream three-axis acceleration data (via USB or UART) for data logging or machine learning purposes. This accelerometer can also do tap recognition and free-fall detection, as well as alerting on motion events and orientation changes, which should be useful for activity tracking.
Of course, you can design your own add-on boards too! While we have no plans for a magnetometer add-on board, you might want to build one yourself to add a compass to your watch. Or an infrared LED for bi-directional communication. The extensible nature of the 9-pin connector makes Sensor Watch Pro a canvas of possibilities: imagine an Arduino you can wear on your wrist for a year on a single charge.
Sensor Watch Pro is open hardware. You can find more information about its hardware and firmware in our GitHub repo.
