What is a sensor?

Sensor A sensor is a device or element that collects information on an object and converts it to a signal that can be processed by a machine.
Geomagnetic sensor Geomagnetic sensors can determine direction by detecting the geomagnetic field.
Pulse sensor ROHM is developing an optical transmission type pulse sensor.
Barometric pressure sensor A barometric pressure sensor is a sensor that detects atmospheric pressure.
Accelerometer sensor Accelerometer sensors are ICs that measure acceleration, which is the change in speed per unit time.
Current Sensor A sensor that measures the current flowing in a circuit is called a current sensor.
Color Sensor Color sensors can detect RGB values by receiving ambient light using a photodiode.
