Need highly precise Qwiic Sensors with Hardware Interrupts (IMU, Light, Sound) for RPi 5

Sensors

Hello everyone,

I am designing an environmental monitoring system housed inside a metal enclosure. It has strict requirements for physical security and tamper-detection. The core of my setup is a Raspberry Pi 5. For project-specific infrastructure reasons, the system must run on standard Ubuntu (NOT the default Raspberry Pi OS).

I am looking for recommendations from the SparkFun catalog for the most precise, reliable sensors capable of continuous 24/7 operation.

My strict hardware requirements are:

  • Hardware Interrupts: The sensors MUST have physical Hardware Interrupt (INT / ALERT / GATE) pins. Reaction time is critical, so I need to use GPIO edge detection in Python instead of CPU-intensive I2C polling.
  • Qwiic Ecosystem: A completely solderless plug-and-play setup wherever possible.

I need sensors to instantly detect the following physical events:

  • Motion / Vibration: A high-end IMU to detect physical manipulation, prying, tilting, or heavy impacts on the enclosure.
  • Light: A high dynamic range ambient light sensor to detect unauthorized opening or breaches (detecting even a tiny amount of light leaking into a pitch-black enclosure).
  • Temperature: A highly precise temperature sensor to detect rapid thermal changes or extreme thermal anomalies.
  • Sound / Noise: A sound detector to catch loud noises like metal grinding, cutting, or drilling. Ideally, one with an adjustable analog threshold and a digital GATE/OUT pin to avoid complex digital audio processing on the Pi.
  • Door/Lid Switch: A reliable mechanical switch to detect if the enclosure is opened.

Before finalizing my parts list for purchase, I have a few crucial questions:

  • Sensor Recommendations: Which specific SparkFun Qwiic sensor boards do you recommend that meet both the high precision and the physical INT/ALERT pin requirements for the categories above?
  • The Solderless Challenge: Standard Qwiic cables only carry the 4 I2C lines (VCC, GND, SDA, SCL). Since I want to avoid soldering but MUST use the physical INT pins for edge detection, what is your recommended, reliable way to route these interrupt pins from the sensor boards back to the Pi’s GPIO? Are there specific terminal block adapters or Qwiic boards with pre-soldered headers you recommend?
  • Ubuntu & RPi 5 Compatibility: Since the RPi 5 uses the new RP1 I/O controller and I am using standard Ubuntu, are the SparkFun Qwiic Python packages fully compatible and tested for hardware GPIO edge detection on this specific OS setup?

Thank you in advance for your expertise and specific part number recommendations!

You’ll have to solder wires to the INT pins on the sensor breakout boards

SparkFun Sound Detector (with Headers) - SparkFun Electronics sound is more tricky…most
microphones/sound detectors are analog at the hobby-level (SparkFun)…I would just wire this to some of the Pi’s other pins

We don’t have much in the way of switches

Fully tested? Oh no. But it all works AFAIK…controller chip shouldn’t matter here

Standard linux distros are not real time operating systems. Please explain, with quantitative examples, what you mean by “Reaction time is critical”.
