This project integrates a temperature and humidity sensor into an IKEA phot frame, creating a smar-home device that blends naturally into any living space instead of standing out as another piece of white plastic hardware.
Built on the Matter protocol for broad smart-home compatibility, the device uses Sensirion's ultra-low-power SHT41 temperature and humidity sensor to achieve exceptionally long battery life. Through careful hardware selection and optimized sleep cycles, the sensor can operate for up to a year on a single battery while remaining fully compatible with major smart-home ecosystems.
