The S22-P430Y/S22-P431Y from SENBA’s SMD-Plastic Sealing Series are compact and high-performance PIR motion sensors designed for precise short-range motion detection with advanced digital integration. Featuring a digital AD serial port output combined with a quad element structure, this series delivers enhanced detection accuracy, improved signal stability, and reduced false triggering in compact sensing applications.
Operating within a low voltage range of 2.2V to 3.7V, these sensors are optimized for battery-powered and portable devices. With ultra-low static current consumption of less than 10µA, they ensure extended battery life and efficient power usage. The sensors support a detection range of 3 to 4 meters when paired with an SB-SF-02 lens, making them ideal for close-range indoor applications.
The focused 80° induction angle enables accurate detection within a controlled area, minimizing unwanted triggers. The large 6.6×6.6mm window enhances infrared signal reception, improving sensitivity and consistency. The digital serial interface allows direct communication with microcontrollers, simplifying system design and improving noise immunity.
Compared to conventional PIR sensors, this series offers superior digital interfacing, enhanced sensitivity through quad structure, and improved reliability, making it ideal for modern compact and sealed sensing solutions.
