What is BUENOFE CO Detector?
Discover the BUENOFE CO Detector, expertly crafted by BUENOFE.
Designed for watching carbon monoxide levels in a tent, cabin or vehicle while a stove or heater is running, it fits perfectly within the Portable CO Detectors category.
Whether you're exploring checking room temperature and humidity when the air is clear or expanding your setup, this product delivers reliable performance.
-
Electrochemical CO Sensor
The sensor responds to carbon monoxide rather than to whatever else is in the air, and it takes a fresh reading once a second.
-
Four Alarm Modes
Pick the mode that suits the space. Modes 1 and 2 start warning at 50 ppm, modes 3 and 4 at 30 ppm, and modes 2 and 4 jump straight to danger at 100 ppm.
-
Alerts On Your Phone
Pair it over Bluetooth and the app raises an alert on your phone when the alarm goes off, as well as the buzzer on the unit. The phone needs to stay within Bluetooth range.
-
Control It From the App
The B-Sync app changes the alarm mode, turns the high-temperature alarm on or off, sets the brightness, switches between °C and °F, tests the buzzer and turns the unit off. You rarely have to reach up to a unit hung near the roof.
-
Colour-Coded LEDs
Green, yellow, orange and red light up the face and the lower panel, so the level reads from across a tent without squinting at numbers. The buzzer also beeps faster as the reading climbs, so the sound tells you the level too.
-
116 Hours Per Charge
The 3,350 mAh battery runs up to 116 hours at minimum brightness and refills over USB-C in 2 to 2.5 hours.
-
Temperature and Humidity
The same screen carries room temperature and humidity, plus a 50 °C / 122 °F high-temperature alarm you can switch on. Hung near the roof, it sits where a heater's warm air collects.
-
Tempered Glass Display
A tempered glass layer sits over the LCD, which is what you want from something that lives in a gear box. Four brightness steps run from readable in direct sun down to a dim glow for a sleeping tent.
Why This Product Exists
From pain points to practical outcomes.
Solutions
-
See A Gas You Cannot
Carbon monoxide has no colour and no smell, so a stove or heater can fill a closed tent without anyone noticing. This puts a live number and a colour in front of you.
-
Set The Threshold Yourself
A fixed 100 ppm alarm is late for a small, closed space. Modes 3 and 4 move the first warning down to 30 ppm so you get told earlier.
-
Know From Outside The Tent
Kids often go to sleep first while the adults stay out by the fire. The alarm sounds inside the tent and, with the app paired and your phone in range, on your phone too.

Frequently Asked Questions
Answers to common product questions.
For gas detection, hang it within 0.3 m (30 cm) of the ceiling, since carbon monoxide mixes through the air and the upper part of a closed space tells you soonest. Loop the strap over a ceiling hook or lantern hanger, or clip it on with a carabiner (not included). Use the back stand only when you are reading temperature and humidity.
They change the ppm band for each LED colour. Mode 1 is 0-49 safe, 50-99 caution, 100-199 warning, 200-1000 danger. Mode 3 moves the first warning down to 30 ppm. Modes 2 and 4 drop the middle warning step and go straight to danger at 100 ppm.
Go by the space. In a small, closed tent, use mode 3 or 4 so the first warning starts at 30 ppm. In a large or well-ventilated shelter, mode 1 or 2 starts warning at 50 ppm. If you are unsure, the more sensitive setting warns you earlier.
Up to 116 hours at the lowest display brightness. Higher brightness and more alarm activity shorten that. A full charge over USB-C takes 2 to 2.5 hours.
No. Everything is set from the two buttons, and the display, LEDs and buzzer all work on their own. Paired over Bluetooth, the app shows the live reading, alarm mode and battery level, alerts your phone when the alarm goes off and can switch the unit off. Phone alerts only work within Bluetooth range.
The app is called B-Sync. Get it from Google Play on Android or the App Store on iPhone, or scan the QR codes in the product gallery. Links to both stores are in the special note under product specifications. When you link your phone, the app texts you a verification code. If the text doesn't arrive, enter 123456 instead.
No. It carries radio and electrical conformity marks for Korea and Japan and has been tested to the UL 2034 test method, but it is not listed or approved as a residential CO alarm. Treat it as a portable supplementary detector, not a replacement for a hard-wired or listed household alarm.
It reads from -30 °C to 60 °C (-22 °F to 140 °F), but the battery drains faster below freezing, so charge it more often in cold conditions.
Press and hold the L button to sound the buzzer. A self-check also runs automatically every time you power it on.
No. Keep it away from water and other liquids, and wipe it with a dry cloth only. There is no stated water resistance rating.
