2PCS D204S Pyroelectric Infrared PIR Motion Sensor for Security System

• The signal-to-noise ratio of the high sensitivity and excellent, excellent environmental stability. Low on power supply interference measures, has the high power interference resistance.Used low resistance capacity filter circuit, resistance capacity frequency selective circuit, enhanced the pyroelectric sensors of the electromagnetic compatibility, the sensor Immunity to radio frequency interference (RFI) is high, can resist the radio frequency interference of outside 1 cm. Low junction field-effect tube in the form of the source follower realize impedance transformation.
• Applicance:Widely used in security systems, burglar alarms, TV, air conditioning, and intellectualized toy, etc.
