Description

The IRA-S210ST01 leverages Murata’s advanced ceramic technology to provide a robust and sensitive pyroelectric infrared sensing element. It detects changes in infrared radiation caused by moving objects, making it ideal for passive infrared (PIR) motion detection applications. The sensor’s internal construction ensures high responsivity and stability.

Designed for long-term reliability, it features a 5-micrometer long-pass optical filter to focus on the relevant IR spectrum and reject unwanted noise. Its wide supply voltage compatibility allows for direct integration into both 3.3V and 5V logic systems, as well as higher-voltage industrial controls, without requiring a dedicated regulator.

Key Features

  • High-performance ceramic pyroelectric sensing element.
  • Excellent signal-to-noise (S/N) ratio for reliable motion triggering.
  • Broad operating voltage range: 2V to 15V DC.
  • Symmetrical 45° x 45° field of view for uniform detection.
  • Integrated 5μm long-pass optical filter.
  • Industrial temperature operation from -40°C to +70°C.
  • Compact lead-type package for through-hole PCB mounting.
  • Typical responsivity of 4.6 mV for high output signal.

Applications

  • Security system motion detectors and intrusion alarms.
  • Automatic lighting control and energy management systems.
  • Consumer electronics for presence detection (e.g., smart TVs, appliances).
  • Occupancy sensing for HVAC and building automation.
  • IoT and smart home devices for motion-activated triggers.

Frequently Asked Questions

What is the operating voltage range for the IRA-S210ST01 sensor?

The IRA-S210ST01 operates from a wide voltage range of 2V to 15V DC. This makes it compatible with common 3.3V and 5V microcontroller systems as well as higher-voltage industrial power supplies without requiring an additional voltage regulator.

How do I interpret the 45° field of view specification?

The field of view is symmetrical, meaning both the horizontal and vertical detection angles are 45 degrees (theta1=theta2=45°). This creates a conical detection zone suitable for general area coverage in motion detection applications like room occupancy sensing.

What type of output signal does this PIR sensor provide?

This is a passive pyroelectric sensing element. It generates a small analog voltage (with a typical responsivity of 4.6 mV) in response to changes in infrared radiation. This raw signal typically requires amplification and conditioning via an external comparator or dedicated PIR amplifier IC (like the BISS0001) to create a digital trigger signal.

Can this sensor be used outdoors?

While its operating temperature range extends down to -40°C, the IRA-S210ST01 itself is not waterproof or sealed. For outdoor use, it must be housed within a protected, weatherproof enclosure with a suitable IR-transparent window to shield it from direct moisture, dust, and condensation.
