(Reuters) -Amazon.com Inc on Wednesday announced a contactless gadget that can monitor people's sleep, along with updates to its lineup of voice-controlled devices and e-readers.

The online retailer said its $139.99 sleep gadget, known as Halo Rise, tracks room temperature, humidity and light, plus the breathing patterns of the person closest to it. The goal is to provide insight to users on why they may or may not feel well-rested when they wake up.
