The BX304/BQ304 High and Low Levels Series PIR motion sensors from SENBA are advanced low-power passive infrared sensing devices designed for precise and stable human motion detection. Featuring high and low level digital output along with a quad element structure, these sensors provide enhanced detection sensitivity and improved noise immunity compared to standard dual-element PIR sensors.
Operating within a low voltage range of 2.2V to 3.7V, the BX304/BQ304 series is optimized for battery-powered and portable applications, delivering ultra-low static current consumption of less than 12µA for extended battery life. With a sensing distance of up to 12 meters when paired with an S9008-2 23mm lens, these sensors ensure reliable long-range detection. The wide induction angle of 120° to 125° enables efficient coverage for medium to large areas.
The quad element design improves signal differentiation and reduces false triggering caused by environmental changes, making it suitable for more demanding sensing environments. Larger window size options (4×4mm / 4.9×4.9mm) enhance infrared reception and provide flexibility in product design.
Compared to conventional PIR sensors, the BX304/BQ304 offers better detection stability, higher sensitivity, and improved resistance to environmental interference, making it ideal for modern smart sensing applications.
