The BS312/BL312/BM312 High and Low Levels Series PIR motion sensors from SENBA are ultra-low power passive infrared sensing devices designed for reliable human motion detection in battery-powered and energy-efficient applications. Featuring high and low level digital output, these sensors enable direct interfacing with microcontrollers and logic circuits, simplifying system design and reducing external component requirements.
Operating within a low voltage range of 2.2V to 3.7V, this series is optimized for portable and battery-driven devices, offering excellent energy efficiency with an 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, these sensors provide extended detection coverage compared to standard low-power PIR solutions. The adjustable induction angles of 120°, 125°, and up to 130° ensure wide-area motion detection flexibility.
Available in multiple window sizes (4×3mm / 5×3.8mm / 5.2×4.2mm), the BS312/BL312/BM312 series supports versatile product designs, from compact portable devices to larger enclosures. Compared to conventional PIR sensors, this series delivers superior low-power performance, stable digital output, and extended detection range, making it ideal for modern smart electronics.
