Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, ...

Smith Systems offers speed sensors for rail applications worldwide, and can even replace problematic OEM sensors with high-reliability models for a fraction of the price. With over 40 years of ...

“Externally mounted sensors significantly increase aerodynamic drag, particularly by increasing the proportion of interference drag within the total aerodynamic drag,” study author Yiping Wang said.

The sensor has a dielectric polymer layer that ... Cup anemometer with separate wind vane - Uses three cups to measure wind speed, while a wind vane measures wind direction. The vane always ...
