[igCS] Sensors

describe how a range of sensors can be used to input data into a computer system, including light, temperature, magnetic field, gas, pressure, moisture, humidity, pH and motion

Sensor is a type of input device

Automatically collect data from physical environment

Sensor usually collects analog data

Detects intensity of ambient light

It can be used in auto night light, or inside a barcode scanner to detect the reflected light from the barcode pattern

Temperature sensor is very common in household environment

e.g. inside AC, electric kettle, heating system etc.

Motion Sensor (able to detect movement, orientation)

Magnetic Field sensor (compass)

Ambient Light sensor

Microphone... and maybe more

Gas sensor

pH sensor

Moisture(soil) and humidity(air) sensor

Pressure
