The S23-S340B/S23-L340B (Indoor) and S23-S341B/S23-L341B (Outdoor) PIR motion sensors from SENBA’s SMD-TO Series are reliable passive infrared sensing devices designed for efficient human motion detection in both indoor and outdoor environments. Featuring high and low level digital output, these sensors allow direct interfacing with microcontrollers and logic circuits, simplifying system design and reducing the need for additional signal processing components.
Operating within a voltage range of 2.2V to 5.5V, this series offers excellent compatibility with low-power and embedded systems. The sensors provide a detection range of up to 10 meters when paired with an S9008-2 23mm lens, ensuring stable and consistent motion detection performance. With a wide induction angle of 120° to 125°, they deliver effective coverage for various application scenarios.
Compact window sizes (4×3mm / 5×3.8mm) enable easy integration into space-constrained designs. With dedicated indoor and outdoor variants, these sensors are optimized to perform reliably under different environmental conditions.
Compared to analog-output PIR sensors, this digital-output series offers simpler integration, faster response, and improved system efficiency, making it ideal for modern smart sensing applications.
