In the Murata SMD TYPE IRS-D200ST00R1
The Murata SMD TYPE IRS-D200ST00R1 is a compact, surface-mountable digital passive infrared (PIR) sensor designed to detect human presence and motion with high reliability in embedded applications. Its standout feature is the ability to be mounted via standard reflow soldering, eliminating the need for manual lead handling and opening the door for full SMT production.
Murata engineered the Murata SMD TYPE IRS-D200ST00R1 to solve a key issue in modern IoT and smart home devices: integrating motion sensing into increasingly miniaturised electronics. By offering a fully digital I²C interface and removing the need for external amplification or analogue front-end circuitry, this PIR sensor makes integration much simpler for hardware developers.
The Murata SMD TYPE IRS-D200ST00R1 offers low power consumption, with standby currents in the nanoamp range, and active sensing typically in the microamp range. This makes it a strong fit for battery-operated products like smart thermostats, video doorbells, wireless security cameras, and presence-aware lighting or HVAC control systems.
In addition to its compact footprint and low Z-height, the Murata SMD TYPE IRS-D200ST00R1 stands out for its high resistance to false triggers from environmental interference. Thanks to Murata’s RF immunity design, the sensor can operate reliably in the presence of 2.4 GHz and 5 GHz signals—important for wireless-enabled designs. The sensor’s robustness in real-world environments ensures it only wakes the MCU or triggers system responses when true motion is detected.
Developers also benefit from flexible configuration options: programmable sensitivity, detection window timing, and interrupt behaviour are all accessible through the I²C interface. Combined with Murata’s application support for lens selection and mechanical integration, the Murata SMD TYPE IRS-D200ST00R1 offers a streamlined path from evaluation to production.
This sensor is ideal for applications requiring digital motion detection with a small form factor, strong EMI resilience, and compatibility with automated PCB assembly processes. The Murata SMD TYPE IRS-D200ST00R1 represents the next step in making PIR technology suitable for mass-produced, space-constrained IoT devices.
