About This
- 【7-in-1 Air Oxygen Monitor】This 7-in-1 multi-functional oxygen detector can detect multiple parameters in real time: CO (0-500PPM), CO2 (400-5000PPM), O2 (0-30%VOL), temperature (32℉-140℉), and humidity (0-95%RH). The rechargeable oxygen monitor also features a flashlight, SD card data storage, and a convenient lanyard, making it not only suitable for indoor air quality monitoring but also an ideal travel companion.
- 【High-Precision Sensors】The O2 monitoring system uses a high-sensitivity DDS sensor imported from the UK, boasting excellent stability and rapid response. The CO monitoring system is equipped with a professional electrochemical sensor, exhibiting extremely high selectivity for CO and capable of sensitively detecting low-concentration leaks. The CO2 monitoring system features an NDIR infrared sensor, offering strong anti-interference capabilities and ensuring long-term stable CO2 measurements.
- 【Dual Audible & Visual Alarm】The oxygen detector is equipped with a 3.27" HD color LCD screen. When any indicator reaches the alarm threshold, the corresponding value on the screen will immediately flash prominently, accompanied by a loud alarm sound. When the alarm sounds, you can choose to temporarily mute it for 5 minutes; if the risk persists, the alarm sound will automatically resume. Alternatively, you can choose to permanently disable the alarm sound, leaving only the visual flashing.
- 【2500mAh Large Battery】This oxygen monitor features a built-in 2500mAh rechargeable lithium battery, coupled with an automatic sleep mode (the screen automatically turns off after 1 minute of inactivity), effectively extending usage time. The inclusion of a universal Type-C interface makes charging more convenient and efficient. Even when charging in sleep mode, the screen backlight remains on, allowing the device to continue operating normally and enabling real-time monitoring while charging.
- 【Calibration Mode】Upon power-on, the oxygen monitor will automatically enter a 1-minute countdown warm-up phase. For oxygen levels, the oxygen detector provides dual automatic calibration values of 20.9% and 0%. Manual calibration is available for carbon dioxide, temperature, and humidity. For safety reasons, carbon monoxide calibration is prohibited.

SMART HOME FAQ
Yes — many modern devices support multiple platforms.
Matter-certified devices can work across Alexa, Google Home, and Apple HomeKit at the same time.
Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
Most homeowners start with:
Smart Security Cameras
Smart Door Locks
Smart Thermostats
Smart Plugs
Video Doorbells
Yes.
Smart thermostats and smart plugs help reduce wasted energy by automating heating, cooling, and power usage.
It depends on your ecosystem.
