A reflective strip is placed on the motor shaft. Each time the strip passes the IR sensor → pulse generated. Arduino counts pulses for 1 second → converts to RPM.

Sony’s IMX775 5-MP RGB-IR image sensor with a 2.1-µm pixel size delivers high sensitivity and a high dynamic range.

A novel spectroscopic method developed at Institute of Science Tokyo, Japan, enables highly sensitive analysis of molecules at material interfaces, using a combination of conventional ATR-IR, precise ...

When taking pictures of the night sky, any noise picked up by the sensor can obscure the desired result. One major cause of noise in CMOS sensors is heat—even small amounts can degrade the final ...
