Baby and Child Monitor: an award-winning wireless monitor

Development of a low-cost, wireless wrist monitor.

Our client asked us to develop a low-cost wrist monitor worn by both the child and the parent for alerting when a baby cries or a toddler wanders off out of range.


Sagentia created a novel, low-power battery-driven radio as a base for the solution that included:-

  • two units, one for the parent and one for the toddler
  • monitoring of up to 3 children simultaneously
  • warnings if a child cries or exceeds a set distance range
  • also monitors room temperature and functions as a digital watch
  • product size of only 35mm


  • ‘Best of Innovation’ winner in the CES Innovation Design & Engineering Awards
  • Battery life of 6 months
  • Highly integrated electronics & design
