Sensor types integrated in PCB

temperature sensor

Thermistors: Their resistance changes with temperature; Therefore, it is very suitable for fairly accurate temperature measurement.

Thermocouples: Due to the proportional temperature difference, they generate output voltage. They are used in industry to control processes.

Pressure sensor

Piezoelectric sensor: an electrical signal that converts pressure, force, or strain into piezoelectric effect.

Capacitive sensors: These sensors measure changes in capacitance caused by diaphragm movement or deformation. They can be used in consumer electronics and automotive systems.

Motion sensor

Accelerometer: Measuring the acceleration force that helps determine the direction of a smartphone.

Gyroscope: The main component that assists in sensing rotational motion and direction, and is very important in land-based vehicle navigation systems and drones.

Light sensor

Photodiode: converts light into current, mainly used for measuring light intensity.

Phototransistor: With higher sensitivity, it is used for precision light detection, such as in safety equipment and automatic lighting.

humidity sensor

Capacitive humidity sensors: Due to changes in the capacitance value of polymer films, they can sense humidity.

Resistance humidity sensors: These sensing elements use the resistance between conductive polymers to detect changes in humidity.

PCB sensors have many sensors, making them very flexible and applicable in various fields from household appliances to heavy industrial machinery. The development of sensors integrated onto PCBs has made modern electronic product designs more compact and functional, highlighting the core value of this advanced technology as a stepping stone.
