Mikroelektronika MIKROE-3339 PIR Click Board Pyroelectric Infrared Sensor

Technical description of the product (MIKROE-3339):

MIKROE-3339. PIR Click is a pyroelectric sensor which generates a voltage when exposed to infrared radiation emitted by live bodies. It is equipped with the PL-N823-01, an infrared sensor from KEMET that uses the pyroelectric effect of ceramic by absorbing infrared rays emitted from the human body, while the white plastic Fresnel lens covering the sensor filters visible light. This detects the natural infrared signature produced by humans. However, it can also detect infrared rays without using lenses. Type: Motion. Applications: Human presence detection sensing for energy saving functions in: contactless switching, office automation equipment, home appliances, lighting, display products, air-conditioners, TV, PC monitors, rice cookers and many more. On-board modules: PL-N823-01, PL Pyroelectric Infrared Sensors from KEMET. Key Features: Wide view angle, detection possible through glass or resin, low power consumption, excellent radio wave performance in high-frequency band, low profile. Interface: GPIO, I2C. Click board size: M (42.9 x 25.4 mm). Input Voltage: 3.3V, 5V.
