The W222S/W222B PIR motion sensor from SENBA is a robust and high-performance passive infrared sensing solution designed for accurate human motion detection in challenging environments. Featuring analog signal output and built-in anti-RF interference capability, this sensor ensures stable and reliable operation even in applications exposed to electromagnetic noise.
With a wide operating voltage range of 2V to 15V, the W222S/W222B offers excellent flexibility for integration into both low-power and standard electronic systems. It supports a sensing distance of up to 10 meters when used with an S9008-2 23mm lens, delivering consistent detection performance across a broad coverage area. The wide induction angle of 120° to 125° enhances motion sensing capability, making it suitable for large-area monitoring.
The sensor maintains a low static noise level of less than 80mV, ensuring clean signal output and reducing the likelihood of false triggering. Its compact window size options (4×3mm / 5×3.8mm) allow easy integration into space-constrained designs.
Compatible with industry-standard PIR controller ICs such as ISB6601L, RS8034, and BISS0001, the W222S/W222B is ideal for use in security systems, smart lighting, and automation solutions. Compared to standard PIR sensors, it provides improved noise immunity, better signal stability, and enhanced reliability in RF-prone environments.
