Overview

The IRS-D200ST00R1 is a surface-mount digital pyroelectric infrared (PIR) sensor designed for human motion detection. It integrates a dual-element ceramic sensor with internal signal processing circuits to provide a direct digital output, simplifying the interface to microcontrollers.

Why Choose This Part

This sensor features a compact SMD package which significantly reduces PCB footprint compared to traditional TO-5 metal can PIR sensors. The digital output eliminates the need for external op-amp stages and analog-to-digital conversion, reducing system noise susceptibility and bill-of-materials cost.

Applications

Intelligent Lighting Control
Automating indoor and outdoor LED lighting based on occupancy to reduce energy consumption.
Security Systems
Low-power motion detection for battery-operated security cameras and intrusion alarms.
Home Automation
Presence detection for smart thermostats, appliances, and HVAC systems to optimize performance when rooms are occupied.
Industrial Equipment
Non-contact human interface activation for kiosks, vending machines, and industrial panels.

Getting Started

Interface this sensor to a microcontroller using a standard GPIO pin to monitor the digital output transitions. Ensure the optical window is correctly aligned with a Fresnel lens suited for your target detection range and field of view. Reference Murata's application notes for recommended PCB landing patterns to avoid thermal stress during reflow soldering.
