CS312/CL312 2.2–5.5V PIR Motion Sensor Serial Output | Digital AD Interface Indoor 10M 125° | SENBA

SENBA

The CS312/CL312 Digital Serial Port Series PIR motion sensors from SENBA are advanced passive infrared sensing devices designed for precise indoor motion detection with enhanced digital interfacing. Featuring a digital AD serial port output, this series enables direct communication with microcontrollers, simplifying system design and reducing the need for external analog signal processing.

Operating within a voltage range of 2.2V to 5.5V, the CS312/CL312 sensors provide excellent flexibility for both low-power and standard embedded systems. With ultra-low static current consumption of less than 12µA, they are highly suitable for battery-powered and energy-efficient applications. The sensors support a detection range of up to 10 meters when paired with an S9008-2 23mm lens, ensuring reliable performance for indoor environments.

The wide induction angle of 120° to 125° allows effective coverage across various indoor spaces, while compact window size options (4×3mm / 5×3.8mm) support easy integration into space-constrained designs. The digital serial interface enables stable data transmission, improved noise immunity, and precise motion signal interpretation.

Compared to traditional analog PIR sensors, the CS312/CL312 series offers enhanced digital integration, reduced design complexity, and improved signal reliability, making it ideal for modern smart sensing applications.
