RDA226S-F Digital Pyroelectric Infrared Sensing Sensor Human Body Sensor Security Lighting Probe

1. Product Description:

The RDA226S-F is a highly integrated digital pyroelectric infrared sensor. It combines a PIR sensing element and a signal processing IC into a shielded package. The sensing element captures infrared signals generated by human movement, transmits them to the high-precision digital processing chip through a differential input method. After signal processing, the sensor directly outputs digital signals, which enables convenient integration into various human - induction - related devices.

2. Key Features:

1. Adopts high - precision AD signal processing technology to ensure accurate conversion and processing of infrared signals.
2. Employs a differential signal input mode, which significantly enhances anti - interference capability and ensures stable performance in complex electromagnetic environments.
3. Equipped with adjustable sensitivity, adjustable delay time, and light control functions to meet diverse application requirements.
4. The enable pin allows users to control whether the sensor outputs signals, improving the flexibility of application.
5. Features a wide working voltage range of 2.2 - 5.0V and low power consumption, suitable for battery - powered devices.
6. Provides digital TTL signal output for easy connection and communication with microcontrollers and other peripheral circuits.

3. Typical Applications:

1. Security products: Such as infrared burglar alarms, security cameras with human body induction triggering function.
2. Human body induction toys: Interactive toys that start or change functions when sensing human movement.
3. Induction lighting and switches: Including corridor induction lamps, bathroom induction switches, and other energy - saving lighting control devices.
4. Industrial automation control: Equipment that triggers relevant operations based on human presence, like automatic door control systems on production lines.
5. Smart home devices: Intelligent appliances such as induction - controlled exhaust fans, air conditioners that automatically start when someone enters the room.
6. IoT terminals: Various terminal devices in the Internet of Things that require human body induction sensing to collect environmental and human activity information.
