The YL312/YM312 Digital Serial Port Series PIR motion sensors from SENBA are high-performance passive infrared sensing devices designed for accurate indoor motion detection with advanced digital interfacing. Featuring a digital AD serial port output, this series allows direct communication with microcontrollers, eliminating the need for complex analog signal conditioning and enabling faster, more reliable system integration.
Operating within a voltage range of 2.2V to 5.5V, the YL312/YM312 sensors provide excellent compatibility with both low-power and standard embedded systems. With ultra-low static current consumption of less than 12µA, they are ideal for battery-powered and energy-efficient applications. The sensors offer a detection range of up to 10 meters when paired with an S9008-2 23mm lens, ensuring dependable performance in indoor environments.
With wider induction angles of 125° to 130°, this series provides enhanced coverage compared to standard PIR sensors. Larger window sizes (5×3.8mm / 5.2×4.2mm) improve infrared reception and support flexible mechanical design.
Compared to conventional analog PIR sensors, the YL312/YM312 series delivers superior digital integration, improved signal stability, and reduced noise sensitivity, making it a strong choice for modern smart sensing and automation systems.
