IRS-D200ST00R1 is a low-power, digital-output SMD thermopile infrared sensor (PIR) launched by Murata.

1. Core Applications

It is specially designed to detect human presence and movement, output digital signals for device wake-up, induction triggering and energy-saving control.

Smart Home: smart lights, thermostats, door & window sensors, doorbells, cameras (human-induced video wake-up)IoT Devices: battery-powered IoT equipment (low power consumption & long standby time)Security Protection: intrusion detection, unattended induction monitoringWhite Goods: human body induction and energy saving for refrigerators, air conditioners

2. Core Functions & Advantages

• Human Infrared Detection: Senses infrared rays at around 10μm emitted by human bodies to detect human movement and presence.

• Ultra-low Power Consumption: Typical operating current of 8μA, supports interrupt wake-up. The device stays in sleep mode normally and activates only when people are detected, greatly extending battery life.

• Digital I2C Output: Built-in amplifier and ADC, direct digital signal output. No peripheral analog circuits required, featuring simple design and strong anti-interference capability.

• Compact SMD Package: Dimension of 6×6×2.6mm, reflow solderable, space-saving and suitable for compact electronic devices.

• High Reliability: High signal-to-noise ratio and excellent EMI resistance to minimize false triggering.
