The Apple HomePod smart speaker delivers more than just room-filling sound. With voice assistant Siri and HomeKit the device offers control of smart home accessories, music streaming, and more. Now thanks to built-in sensors, the HomePod can monitor indoor temperature and humidity levels. Current readings can be viewed directly in the Home app.

Apple has been working on non-invasive technology to measure blood glucose levels. These sensors would use optical absorption spectroscopy to calculate blood sugar levels through the skin, making pin pricks for blood samples unnecessary. Rumors have pointed to a future Apple Watch with built-in glucose monitoring in development.

Apple Watch continues to add new ways to measure personal health metrics, thanks to specialized components inside the device. The Apple Watch Series 8 and later includes a variety of sensors to collect biometric data from the wearer. Information can then be viewed and tracked in both the Health app and the Fitness app.
