The Silent Killer You'll Never See Coming

Here's the terrifying truth: carbon monoxide kills you while you sleep, and you'll never know it's happening. No smell. No color. No warning. The early symptoms mimic the flu perfectly. Headache, dizziness, nausea. So you dismiss it. "Must be the altitude."

Meanwhile, the Mars Fabisense detector would be screaming at you to evacuate because that propane heater is slowly suffocating you.

Tents, vans, and cabins trap air viciously fast. Your stove? Carbon monoxide. Your charcoal? Carbon monoxide. That generator twenty feet away? Carbon monoxide drifting everywhere.

ProTech interviewed over 200 adventurers over five years. Same frustration every time: you can't monitor what you can't measure.

Professional-Grade Sensors That Actually Fit in Your Pocket

Mars Fabisense is smaller than your phone and weighs less than a deck of cards (74mm x 74mm x 32mm, 80 grams total). You could literally forget it's in your pack.

But inside that tiny package? UL-certified electrochemical sensors that respond in under 3 seconds with accuracy that meets professional laboratory standards.

Carbon Monoxide: The 50ppm Alarm That Saves Your Life

CO detection covers 0-1000ppm with ±5ppm accuracy. The alarm screams at 50ppm, which is the exact threshold where prolonged exposure transitions from "uncomfortable" to "dangerous."

This isn't some cheap Amazon sensor that sorta-maybe detects gas presence. This is certified precision making the invisible visible before your body realizes something's wrong.

Charcoal camping? You need this. Propane heating? You need this. Generator nearby? You desperately need this.

Carbon Dioxide: The Wake-Up Call Your Brain Needs

CO₂ monitoring hits 400-5000ppm range with surgical precision. At 2000ppm, Mars starts nagging you to ventilate because that's the level where your brain function quietly degrades and sleep quality tanks.

You wake up feeling like garbage and blame the sleeping pad, never realizing you spent eight hours marinating in your own exhaled CO₂. In sealed spaces, this builds shockingly fast.

Mars shows you the invisible truth: that "bad sleep" is actually suffocation.

Temperature and Humidity: Because Hypothermia Kills Too

Accurate temp tracking (-10 to 50℃, ±1.0℃) and humidity monitoring (0-95%RH, ±5%RH) calculate real-time apparent temperature. This is the actual thermal stress your body experiences.

This isn't luxury data; it's survival information. Are you dressed warm enough? Is that shivering dangerous? Mars tells you with numbers instead of guesswork, preventing the hypothermia that sneaks up when you're focused on other dangers.

The App That Turns Data Into Lifesaving Action

Raw sensor readings won't save you. Understanding what those numbers mean will. The Mars Fabisense detector app transforms technical data into "GET OUT NOW" clarity.

Live Monitoring With Color-Coded Panic Levels

Green means breathe easy. Yellow means pay attention. Red means evacuate immediately. The app mirrors Mars's physical display with color-coding so obvious that you understand danger levels instantly.

And here's the killer feature: if CO or CO₂ spike while you're outside grabbing firewood or using the bathroom, your phone screams at you. The tent might be fifty feet away, but the app ensures you know danger is brewing before you crawl back inside.

Trend Charts That Teach You How Air Actually Works

The 24-hour and 7-day charts aren't just pretty graphs. They're education. Watch CO₂ climb every night in your sealed van and suddenly you understand why mornings feel rough.

See CO spike every time you cook and realize your ventilation strategy is garbage. Track how cracking a window changes everything. Patterns you never knew existed become obvious, turning Mars into a teacher that improves your safety instincts permanently.

Plus, the device locator feature finds Mars when it's buried in gear. One tap triggers beeping and flashing within 30 meters. Over-the-air updates mean Mars gets smarter over time without buying new hardware.

Built To Survive What Kills Other Electronics

The Mars Fabisense carbon monoxide detector survived 1.5-meter drop tests and sand erosion testing because outdoor gear lives rough lives. High-strength ABS plastic shrugs off impacts that would shatter cheap detectors.

Magnetic backing slaps onto van walls, cooking setups, or any metal surface. No drilling, no mounting hardware, just instant secure placement. The foldable stand props it on desktops, tent floors, or cabin shelves. Lanyard holes with detachable strap mean backpack carry without adding noticeable weight.

The 2100mAh battery runs for days on a single charge, and USB-C charging uses the same cable as your phone. One less thing to pack.

Oh, and that built-in flashlight? High-lumen output that turns night navigation or emergency lighting into actual capability instead of dim joke. This thing was designed by people who actually go outside, not engineers who think "outdoor use" means a suburban patio.

ProTech Knows What They're Doing

ProTech International Group has spent a decade building precision environmental sensors and portable detection equipment used in homes, industries, laboratories, and actual outdoor environments worldwide.

They're not Kickstarter newbies hoping their prototype works. They're repeat creators with three successful campaigns proving they understand manufacturing, shipping, and delivering products that actually function.

As engineers and outdoor enthusiasts themselves, they've personally felt stale tent air and uncertain propane heating. Mars represents their answer: professional accuracy without professional bulk or pricing, backed by a team that's already delivered thousands of devices to satisfied customers.

How Mars Fabisense Detector Destroys the Competition

Basic home CO detectors ($20-$50) only detect carbon monoxide. No CO₂, no temp, no humidity, no portability, no app, no useful data beyond "beep loud when bad."

Professional multi-gas monitors ($200-$500+) deliver accuracy but weigh pounds and cost fortunes. Nobody's backpacking with those.

The Mars Fabisense carbon monoxide detector at $42.99 combines UL-certified dual-gas detection, environmental monitoring, app connectivity, flashlight, magnetic mounting, and legitimate 80-gram portability. You're getting professional capability at consumer pricing from proven creators instead of gambling on first-time Kickstarter hopefuls who've never manufactured anything.

Campaign Update # 1 — January 9, 2026

The Mars Fabisense carbon monoxide detector on Kickstarter continues to gain strong traction, now sitting at US$59,516 pledged from 975 backers, with 14 days remaining.

Last week, the team shared a holiday update confirming that current Mars Fabisense units actively monitor carbon monoxide, CO₂, temperature, and humidity to support safer indoor environments. They also announced plans for a future upgraded version featuring TUYA Smart integration and Amazon Alexa support. This smart-enabled model will launch after the campaign and will be a separate release, as existing units cannot be upgraded.

Backers were reassured they’ll receive early access and exclusive offers once the smart version is ready, reinforcing long-term support for the Mars Fabisense ecosystem.
