Sensor Wikipedia
MOS technology is the basis for modern image sensors, including the chargecoupled device (CCD) and the CMOS activepixel sensor (CMOS sensor), used in digital imaging and digital cameras. Willard Boyle and George E. Smith developed the CCD in 1969. While researching the MOS process, they realized that an electric charge was the analogy of the magnetic bubble and that it could be stored on …
Guide for MQ2 Gas Sensor with Arduino | Random Nerd Tutorials
20160505· The MQ2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...
