The project shared by you for smart watch is super inovative idea.
I am planning to create a product which can display Humidity and Temprature of a place, and display data remotely on MQTT server as well as on a OLED attached to the PCB.
Lateron, I wish to more sensors. ( I2C ,SPI,ADC)
Is there any PCB which uses Humidty and Temprature sensor of microchip SHT45.
As the time is less , I wanted to know if the design ready for production and also , if there is any source code which I can modify.
