BS412/BL412/BM412 2.2–3.7V PIR Motion Sensor Digital Output | Adjustable Delay 12M 130° | SENBA

The BS412/BL412/BM412 High and Low Levels Series PIR motion sensors from SENBA are advanced low-power passive infrared sensing devices designed for precise human motion detection in modern electronic applications. Featuring high and low level digital output with adjustable delay functionality, this series enables flexible timing control, allowing designers to optimize response duration based on specific application needs.

Operating within a low voltage range of 2.2V to 3.7V, these sensors are ideal for battery-powered and portable systems, delivering excellent energy efficiency with ultra-low static current consumption of less than 12µA. With a sensing distance of up to 12 meters when paired with an S9008-2 23mm lens, the BS412/BL412/BM412 series provides extended detection capability compared to standard low-power PIR sensors. The wide induction angles of 120°, 125°, and up to 130° ensure comprehensive area coverage.

Available in multiple window sizes (4×3mm / 5×3.8mm / 5.2×4.2mm), these sensors offer flexible integration into various product designs. Compared to conventional PIR solutions, this series delivers enhanced control through adjustable delay, stable digital output, and superior low-power performance, making it highly suitable for intelligent sensing systems.
