Design and development of wireless baby monitors

The Philips DAP SCD510, SCD520, SCD530, and SCD540 1.8GHz/1.9GHz DECT Digital Wireless Baby Monitors are part of the next generation digital baby monitor products that emphasize on small form factor, innovative feature set, and cost effective bill of materials. New product features include wideband audio, ambient relative humidity measurement, and carbon monoxide detection. The objectives of this project are to design and develop these four baby monitor products and begin mass production for the 1st model within the ten-month time frame. The scope of this project includes baseband hardware design, battery charging algorithm design, and carbon monoxide detection algorithm design. This project report presents the baseband hardware design and implementation, outlines battery charging considerations, describes the battery charging algorithm implementation, examines carbon monoxide detection requirements, and presents the carbon monoxide detection implementation in detail.
