The S23-S330W/S23-L330W (Indoor) and S23-S331W/S23-L331W (Outdoor) PIR motion sensors from SENBA’s SMD-TO Series are high-performance passive infrared sensing devices designed for accurate and stable motion detection across diverse environments. Featuring analog signal output combined with a quad element structure, this series delivers enhanced sensitivity and improved noise immunity compared to standard dual-element PIR sensors.
Operating within a wide voltage range of 2V to 15V, these sensors offer excellent flexibility for integration into both low-power and industrial electronic systems. With a sensing distance of up to 10 meters when paired with an S9008-2 23mm lens, they provide reliable detection performance. The wide induction angle of 120° to 125° ensures effective coverage for both indoor and outdoor applications.
The quad element design significantly improves signal differentiation, reducing false triggering caused by environmental disturbances such as temperature fluctuations or background noise. With low static noise of ≤80mV, the sensors ensure clean and stable analog output. Larger window size options (4×4mm / 4.9×4.9mm) enhance infrared reception and support flexible mechanical design.
With dedicated indoor and outdoor variants, this series is optimized for varying environmental conditions. Compared to standard PIR sensors, it offers superior detection accuracy, higher stability, and improved reliability in real-world applications.
