Murata Unveils Compact IRS-D200ST00R1 SMD Pyroelectric Infrared Sensor for Smart Home IoT Applications

Murata  has launched the IRS-D200ST00R1, a digital output SMD pyroelectric infrared sensor designed for low power consumption, now in mass production. The sensor targets IoT applications in smart homes and buildings, where demand for wireless communication units with real-time human detection is growing to enhance convenience, safety, and energy efficiency.

The IRS-D200ST00R1 addresses the need for compact, low-power sensors to support long-term battery operation in wireless devices. It utilizes Murata’s proprietary pyroelectric ceramic technology, featuring low power consumption and an interrupt function that activates the microcontroller only upon detecting movement, extending battery life. The sensor’s compact size and digital I2C interface simplify integration into space-constrained designs.

Key features include a dual element electrode (2.0 × 0.5 mm), overall dimensions of 6.0 × 6.0 × 2.6 mm, and an element height of 1.65 mm. It offers a field of view of ±55° horizontal and ±42° vertical, a typical sensitivity of 19.5 mV, and operates on a supply voltage of 1.8 to 3.3 V with a typical current consumption of 8 µA. The sensor provides a high signal-to-noise rat...
