The S22-P330Y/S22-P331Y from SENBA’s SMD-PCB Series are compact and energy-efficient PIR motion sensors designed for precise short-range motion detection with advanced digital interfacing. Featuring a digital AD serial port output, this series enables direct communication with microcontrollers, simplifying system design and eliminating the need for complex analog signal conditioning.
Operating within a low voltage range of 2.2V to 3.7V, these sensors are optimized for battery-powered and portable electronic devices. With ultra-low static current consumption of less than 10µA, they ensure extended battery life and efficient power management. The sensors provide a detection range of 3 to 4 meters when paired with an SB-SF-02 lens, making them ideal for close-range sensing applications.
The focused 80° induction angle allows accurate detection within a confined area, reducing false triggers from unwanted motion. A large 6.6×6.6mm window enhances infrared signal reception, improving sensitivity and stability. The digital serial interface offers reliable data transmission with improved noise immunity.
Compared to traditional analog PIR sensors, this series provides superior digital integration, reduced system complexity, and stable performance, making it ideal for modern compact sensing applications.
