Pyroelectric Infrared Sensor

Pyroelectric Infrared Sensor developed and supplied to the market by NiCeRa is being used worldwide for manyapplications. For example, light switch control, visitor acknowledgement, security systems and burglar alarm.Utilizing our expertise gained by years of experience, we satisfy marketing needs for high quality and low cost.

This is called Pyroelectric Effect.

When ferroelectrics receive infrared and absorbs the thermal energy, a change occurs in its spontaneouspolarization, and electrical charge will be excited on its surface in proportion to the amount of change.
