Technical Specifications

Safety Precautions

• Do not exceed the range of ratings, environment conditions, or other specifications.
• Use with proper fire-prevention, safety, and maintenance measures.
• Verify pin layout before connecting to prevent damage.
• Do not use disassembled or remodeled sensors.
• Consider failure modes (short-circuiting, open-circuiting, temperature rises) for safety-critical applications.

Operating Precautions

• Detects variations in infrared rays; may not detect lack of movement or temperature change.
• Can detect heat sources other than human bodies (small animals, sunlight, strong light beams, HVAC wind, humidifier vapor).
• Detection may be difficult through glass/acrylic, or with non-movement/quick movements.
• Detection range may widen with significant temperature differences.
• Occasional unnecessary detection signals may occur due to the nature of the pyro-electric element.
• Optimal operating conditions: Temperature (-20 to +60C), Humidity (15-85% Rh, avoid condensation/freezing), Pressure (86-106kPa).
• Not waterproof or dustproof; avoid excessive moisture, condensation, frost, salt air, or dust.
• Avoid environments with corrosive gases.
• Soldering: Max 350C for 3 seconds, hand soldering recommended.
• Mount on a printed circuit board for stability.
• Do not wash the sensor with liquids.
• Avoid using sensors that have fallen on the ground.
• Sensitive to static electricity (200V); avoid direct hand contact with pins.
• Use shielded cables and minimize wiring length to prevent noise.
• Use of surge absorption elements is highly recommended.
• Use a stabilized power supply; power supply noise can cause errors.
• Operating errors can be caused by various noise sources (static electricity, lightning, cell phones, etc.).
• Keep the lens clean for optimal detection performance.
• The lens is made of soft material; avoid adding weight or impacts.
• Operating temperature and humidity are suggested for longevity but do not guarantee durability.
• Do not clean with detergents or solvents like benzene or alcohol.
