New Casio wears operating system smartwatch to add heart rate sensor
Up to now, every Casio smartwatch has a strange missing function, which is the heart rate monitor. At Casio WSD-F21HR, this problem has finally been solved by providing you with HR sensors such as Casio smartwatches.
But Casio cannot overly reduce the important price of a smartwatch. But considering the addition of HR sensors, the price has not increased much, which is refreshing.
As Casio WSD-F21HR 's name suggests, the device is not the successor to WSD-F30 in 2018. Instead, it is an iterative upgrade of the Casio WSD-F20 in 2017. The WSD-F21HR uses a heart rate sensor and looks a lot like the F20.
As expected, the heart rate sensor exists below the body of the watch and works by emitting green light to the wrist.
Like other Casio smartwatches, the Casio WSD-F21HR runs on the Wear OS, so heart rate sensors will be used in conjunction with Google Fit or other Wear OS fitness tracking applications. It is also equipped with the previously known high-precision GPS sensor technology of the Casio smartwatch.
Starting in September, WSD-F21HR can be bought for $500. The device comes in two colors: red and black.
