The first electric fire detector was developed in Brooklyn, NY in 1863 by Alexander Ross, however the first electric fire sensor to see commercial use was designed by another New Yorker, William B. Watkins. By the early 1870's, Watkins had developed remotely monitored fire alarm systems using heat detectors and in 1873 formed the first private fire alarm company (Boston AFA) which surivives to this day as AFA Automatic Fire Alarm) Protective Systems.

When was a motion detector invented?
The first motion detector was invented in the early 1950s by Samuel Bagno. He developed a device that could detect motion using a technology called ultrasonic waves. This early version of a motion detector paved the way for the more advanced versions we use today.
Who invented the ice detector?
The ice detector was invented by Dr. Ted Fujita, a Japanese-American meteorologist. He developed the first ice detectors in the 1960s to improve aviation safety during icy conditions.
What happend when a convection current detector came near a heat source?
When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.
Who made the motion detection device?
The motion detection device was invented by Samuel Bagno in the early 20th century. He developed the first motion detector to detect intruders by sensing their movement.
Who invented the lightning detector?
The lightning detector was invented by Alexander McAdie in the late 19th century. He developed a device that could detect and track the radio signals produced by lightning strikes, leading to the first practical lightning detection system.
