S23-S340R/S23-L340R/S23-S341R/S23-L341R 2.2–5.5V PIR Motion Sensor Serial Output | AD Interface Indoor/Outdoor 10M 125° | SENBA

The S23-S340R/S23-L340R (Indoor) and S23-S341R/S23-L341R (Outdoor) PIR motion sensors from SENBA’s SMD-TO Series are advanced passive infrared sensing devices designed for accurate motion detection with efficient digital interfacing. Featuring AD signal serial port output, this series enables direct communication with microcontrollers, simplifying system design and reducing the need for external analog processing circuits.

Operating within a voltage range of 2.2V to 5.5V, these sensors are well-suited for low-power and embedded applications. They provide a sensing distance of up to 10 meters when paired with an S9008-2 23mm lens, ensuring reliable detection performance. The wide induction angle of 120° to 125° allows effective coverage for both indoor and outdoor environments.

Compact window size options (4×3mm / 5×3.8mm) support easy integration into space-constrained designs. With dedicated indoor and outdoor variants, this series is optimized to deliver stable operation under different environmental conditions.

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