Ray Higgs, of Dunmow, dreamt up the A-OK care monitor in 2006, after his late father, Ron, 84, suffered a minor stroke.
The device allows family members to keep a “discreet eye” on lonely individuals in their homes without any cameras.
“My dad pleaded with us not to take him to a home, but I could not leave him alone, I had to do something,” said Ray, 56.
The monitor works with sensors that send a text to a family member when there has been no movement detected in the home.
A text is sent when the person has not moved in the morning, afternoon, or any time programmed into the device, when they are supposed to be up and about.
