From CNET: Fitbit, now a part of Google, is working on developing the Pixel Watch this fall. But there are also other new Fitbits, as Fitbit head James Park told CNET earlier this year. The Fitbit Sense 2, a sequel to the sensor-packed Sense watch released two years ago, is arriving this fall alongside a GPS-equipped Versa 4 watch and a new $99 color-screened Inspire 3.
Where the Sense 2 may most differ from the expected Pixel Watch is in its use of a wider range of sensors, while keeping compatibility with both the iPhone and Android phones.
The original Sense added skin temperature sensing, a feature that's since been used in wearables like the Samsung Galaxy Watch 5 and is expected on the next Apple Watch. It also had an electrodermal activity sensor that aimed to measure stress levels through palm contact with the watch face. Both those features are now on the smaller, less-expensive Fitbit Charge 5.
The $300 Sense 2 adds another type of sensor tech Google and Fitbit are calling cEDA, or "continuous electrodermal activity." The previous Sense watch had to rely on spot checks with the EDA sensor to look for possible signs of stress, while the Sense 2 promises to scan continuously with a rear electrical sensor, combining with the optical heart-rate sensor to look for daily moments where possible stressors might pop up.
