S23-S330Y/S23-L330Y/S23-S331Y/S23-L331Y 2.2–5.5V PIR Motion Sensor Serial Output | AD Interface Indoor/Outdoor 10M 125° | SENBA

The S23-S330Y/S23-L330Y (Indoor) and S23-S331Y/S23-L331Y (Outdoor) PIR motion sensors from SENBA’s SMD-TO Series are advanced passive infrared sensing devices designed for precise motion detection with digital integration. Featuring AD signal serial port output, this series enables direct communication with microcontrollers, simplifying system architecture and eliminating the need for complex analog signal conditioning.

Operating within a voltage range of 2.2V to 5.5V, these sensors provide excellent compatibility with low-power and embedded electronic systems. They deliver a sensing distance of up to 10 meters when paired with an S9008-2 23mm lens, ensuring stable and reliable detection performance. The wide induction angle of 120° to 125° allows efficient coverage across both indoor and outdoor environments.

With compact window size options (4×3mm / 5×3.8mm), the sensors support easy integration into space-constrained designs. Dedicated indoor and outdoor variants ensure optimized performance under different environmental conditions.

Compared to traditional analog PIR sensors, this serial output series offers improved signal stability, enhanced noise immunity, and simplified system design, making it ideal for modern smart sensing and IoT applications.
