• Ogygen Tank Gauge Wireless Monitoring: Altus
  • Wireless Oximeter SPO2 Monitoring: Illyrian


Founded by pilots, Aithre technology was originally developed to improve the safety of flight at high altitudes where oxygen is low and risks are high.  Through innovation, we've created temple or forehead positioned oximeters, CO detectors, and oxygen pressure monitors that are BLE enabled for wireless continuous monitoring on iOS and WatchOS for aviation, sleep, and mountainnering environments. 


  • iOS & WatchOS ENABLED

    The Aithre Connect app is available free from the Apple Store and auto pairs to each Aithre device.


    Keep you and your passengers, team, and family members safe with centralized iOS health monitoring of carbon monoxide, portable oxygen, heart rate, and blood oxygen levels.


    Continuously monitor up to six team members simultaneously on your iOS device using auto-pair and auto-discovery BLE communication.


Position our pad-type pulse oximeter on your forehead, under your earlobe, or even on your temple to get real-time blood oxygen readings on your iPhone and Apple Watch.  Wireless data and convenient USB power.  


Plot your real-time & trend pulse ox data on your Apple iOS device during sleep, flight, or hiking.  


Our Shield EX are compatible with Advanced, Skyview, and G3x to provide CO and Tank PSI output as graphical engine gauges.  Simple installation, 1.1 ounce weight, and 1.75" x 1.75" x 0.65" size are the reason with Vans Aircraft has selected the EX for its RV-12iS aircraft! 


Convert any portable oxygen tank into a smart tank with wireless pressure monitoring, flow rate calculations, and time remaining determinations.  Monitor on your iOS or WatchOS device in real-time.


A simple glowing indicator allow this rechargeable carbon monoxide detector to be used with or without the BLE and iOS application.  Ideal for portable on-the-go use where precision is a matter of life and death.

    This morning we launched from Missoula in Miss Montana enroute Normandy to participate in the 75th anniversary of DDay celebrations. Onboard we have an Aithre Shield CO monitor developed by a fellow RV10 builder. We love it, the ability to move it around in our large DC3, read and store results in the app, and have confidence our 75-yr old airplane is safe. Great product.

    Through various updates and Aithre's demonstrated commitment to safety and their product line, they have now achieved a wicked risk-mitigation solution to the carbon monoxide threat in the everyday general aviation pilot world.  Aithre didn't just talk about future improvements, they did something about it in quick fashion.  When it comes to CO awareness I trust my life and my family's lives to Aithre

    Just as I was departing to the practice area while keeping an eye on the Shield, it goes red.  That's it, I've got a confirmed exhaust leak.  I immediately pull a tight right to re-enter the pattern while closing the heat control and dumping some fresh air in.  On downwind I got it to drop back to 3 amber flashes and finished out the flight with the amber flashes reducing.  After the flight, I realize I've got a bit of a headache that I know came from the CO levels.  After securing my plane, I reached over and yanked that stupid CO dot off the panel, which crumbled onto the ground.  THANK YOU for this wonderful little device.

    Just a quick note to say what a great product!  I’ve been using it now for a couple of months, and it’s so good it’s picking up the CO levels in the L.A. basin (1 to 4 PPM depending on where and what time of day)!  At first I thought it was slightly miscalibrated, but then I checked the South Coast Air Quality Management District web pages for L.A. Basin air condition figures (lots of data) for CO, and guess what?  It was reading the *ambient* CO in the air in L.A. correctly!  Actually, *very* accurately…impressive!

    I'm very happy I got the Shield.  I'm learning a lot about the CO levels in my airplane, and I seem to notice a trend.  It seems to spike at high AOA and is at zero during cruise, event with the heater on.  That's a relief to know that I don't seem to have an exhaust leak, but possibly a door seal leak, or maybe just normal entry from the wing vent intake. Thanks again for a great product!

  • J.M.

    I did collect some interesting data on Sunday.  During flight, cabin reads '0'.  During engine startup, I got one reading to 10ppm.  Closing my window air vents reduced this to 7ppm.  Slow taxi is 4ppm with the windows closed.  My door seals are REALLY bad, so I get plenty of fresh untainted air during flight.  Thank you again.

  • J.H.

    The app worked well.  In my own aircraft it was interesting to see small peaks of CO in the cockpit during takeoff run and when the apparent wind is in certain direction relative to the exhausts (when taxiing).  Only comments were that it would be useful to have a data logging function on the app so that you can scroll back and see where the peaks in CO were relative to time.  That would be useful - but overall, super product.
