Hello, I am electronic engineering student. I want to ask question for my project. We all know that smartwatch has a lot of sensor. I have survey 10 manufactures of smartwatches and I found that most of the smartwatches don't provide a feature of ambient temperature and humidity sensor. The only temperature sensor that is installed is body temperature. My questions are: There are a lot of types of sensors in a smartwatch (Like body temperature and GPS) which are used to collect data to be processed. Is there any demand for the data of ambient temperature and humidity of the environment of the user? Are there any data that is wanted by any company, for example by meteorology organizations or medical companies? If I want to integrate this sensor to my smartwatch, I would need to design it so that this sensor will not be influenced by external factors like the local temperature (ie: Body heat, display, processor). At the same time, I also need to provide pathways for air from the environment to the sensor. What do you think is another problem that I would face other than the above?
