Rapid growth in the global motion sensors market is being driven particularly by demand for microwave motion sensors, according to Transparency Market Research.

Microwave motion sensors like the Ex-Mo Motion Sensor employ the Doppler principle to detect movement by measuring changes in the wavelength of microwaves reflected back to the sensor by moving objects like vehicles and people.

This allows automated switching of electronic devices, for example motion triggered night-time lighting for hazardous areas, reducing energy costs while removing the need for manual switching upon entry into the area.

In a report published earlier this year, Transparency identified microwave motion sensors as a major driving force in the market in 2018, saying the technology is currently in “strong demand”.

The analysis is backed up in figured from Zion Market Research published in September, which forecast substantial growth in the global motion sensors market in the years to come.

Zion’s calculations use 2016 as a baseline, when revenues worldwide from motion sensor sales reached just under $4 billion.

But by 2022, this is predicted to more than double, to in excess of $8 billion, achieving a compound annual growth rate of 12.8% across all motion sensor technologies, microwave included.
