The Pyroelectric InfraRed(pir) motion detection sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature.

Feature for pir sensor:
Dual compensated sensing elements in the PIR sensor are applied to suppress the interference resulting from temperature variation. As a result, the operating stability of the sensor is greatly improved.

Typical Applications for motion sensor
1. Security systems
2. Burglar alarms
3. Visitor acknowledgement
4. Lighting switch control
5. Intellectualized toy, etc.

Ultra-thin Joint Torque Sensor accurately and sensitively measures torque applied to robot joints,
enabling precise collision detection and torque control in a compact design.
This Ultra-thin joint torque sensor is designed to selectively measure rotational torque along a single axis by distinguishing and extracting it from external forces consisting of 3-axis forces and 3-axis moments.
It is primarily used in specialized situations where only torque needs to be extracted or in motors that generate torque.
