Summary
INO has designed a compact optical sensor capable of distinguishing dust, soot, and hazardous particles in real time, reducing false alarms and increasing safety on space missions.
Smoke detectors used on the International Space Station missed more than 50% of smoke events during tests with common materials such as Teflon and Kapton.
Conventional photoelectric detectors only measure the light scattering of a laser beam. In microgravity, floating dust generates false alarms, forcing scientific experiments to stop and lowering crew attentiveness.
Furthermore, these systems are insensitive to ultrafine particles (0.1–0.3 µm), which are common in spacecraft materials.
INO has developed a patented optical technology that surpasses the capabilities of traditional photoelectric detectors.
It doesn’t simply detect the presence of particles—it measures their size, type, and distribution in real time.
✅ Early detection of fine particles before complete combustion
✅ Reduced false alarms thanks to the ability to distinguish dust from soot
✅ Continuous monitoring with minimal power consumption
✅ Compact, no moving parts—ideal for long-duration missions
INO’s prototypes have demonstrated their effectiveness in detecting:
Tests confirmed the sensor’s ability to distinguish particle types from 0.02 to 2.5 µm, with growing sensitivity up to 10 µm.
With no moving parts or pumps, the system provides increased reliability and minimal maintenance—a critical advantage for long-term space missions.
As space agencies plan habitats on the Moon and Mars, INO’s technology is emerging as a unified system for airborne hazard detection.
It meets NASA requirements for safety, fine particulate (PM) monitoring, and protection against lunar dust.
Why Is Optical Detection Essential in Microgravity?
Because in space, particles remain suspended far longer. Only sensitive optical detection can quickly identify early signs of fire or contamination before they become dangerous.
How Is INO’s Technology Different from a Conventional Detector?
It measures the size, distribution, and nature of particles rather than simply detecting their presence, which significantly reduces false alarms and improves system reliability.
Can This Technology Be Used Beyond Space Applications?
Yes. It can be adapted to any high-risk confined environment: submarines, laboratories, industrial facilities, or mining operations.
