1 System Overview
The Carbon Monoxide (CO) Breath Sensor System (COBSS) consists of a personal mobile
breath sensor (CO Breath Sensor) capable of measuring a user’s level of CO in their exhaled
breath and a Breath Sensor App (BSA) for smartphones which displays the exhaled breath
CO value to the user.
2 Background Information (Smoking and Breath Carbon Monoxide)
Smoke from a burning cigarette contains high levels of carbon monoxide or CO (a by-
product of combustion). When cigarette smoke is inhaled into the lungs, CO enters the
bloodstream. Over time, the CO is slowly released in the exhaled breath. The level of CO
in exhaled breath can be measured using the CO Breath Sensor and the Breath Sensor App,
which together, make up the CO Breath Sensor System or COBSS.
The amount of carbon monoxide in the exhaled breath of a smoker is related to the
intensity, frequency, technique and amount of smoking behavior. Simply put, the more
one smokes, the higher their exhaled breath CO levels tend to be. When a smoker stops
smoking (smoking cessation), their exhaled breath CO levels drop within a few days to
values seen in non-smokers. Exhaled breath CO readings have been shown to be useful for
smokers who are trying to quit smoking (smoking cessation), as the personal CO
information provides educational feedback regarding their smoking exposure.
3 Indications for Use
The Carbon Monoxide Breath Sensor System is a breath carbon monoxide monitor
intended for single-user use in smoking cessation programs.
4 Contraindications
There are no known contraindications at this time.
5 Warnings
Low levels of CO do not indicate that it is safe to increase your smoking. Smoking is
harmful to your health and any amount of smoking is unsafe.
6 Precautions
Sit down while doing breath samples. Holding your breath and then blowing into the
device may cause some users to become lightheaded, which may lead to falls.
Do not strain while doing a breath sample, as this may cause lightheadedness, which
may lead to falls.
Carrot Sense, Inc. Carbon Monoxide (CO) Breath Sensor System (COBSS)
User Manual
2
When taking a deep breath in to do a breath sample, do not take this breath in through
the straw or CO Breath Sensor.
Do not use the COBSS while operating any type of vehicle or machinery as you may be
distracted from the operation.
After cleaning straws with soap and water, ensure they are dry inside and out before
using.
The straw is a small part and may be a choking hazard. Keep away from children under
3 years.
Do not use any alcohol containing products, such as alcohol wipes or gel, on the CO
Breath Sensor as they may interfere with the function of the CO Breath Sensor and CO
values.
Do not submerge the CO Breath Sensor in water or other liquids.
7 Notes
Do not use in cases of suspected carbon monoxide poisoning. Call 911.
Do not use in cases of suspected smoke inhalation (e.g. from a fire). Call 911.
Do not use the CO Breath Sensor while plugged in for charging as it will not function.

9.2 Cleaning
Cleaning is optional. If you choose to clean, use a lightly damp clean cloth to wipe
down the outside CO Breath Sensor. Do not allow water to enter any openings in the
device.
9.3 Straws
Straws are reusable and may be cleaned. To clean, wash with mild hand soap and
warm water and allow to completely dry before use. Replace as necessary.
10 Breath Sensor Application
10.1 Pairing to Smartphone
See Product Specifications for compatible smartphones to pair with your CO Breath
Sensor. Follow these steps to pair:
a. On your smartphone, download and install the My Breath CO application from
the Apple App Store (iOS) or Google Play (Android).
b. On your smartphone, turn Bluetooth “on.
c. Open the My Breath CO application. You will see a welcome screen followed by
a Breath Sensor Pairing animation.
d. Your smartphone will look for any available, ready-to-pair, CO Breath Sensors.

e. To make your CO Breath Sensor available for pairing, press and hold the CO
Breath Sensor button until the LED flashes cyan (light blue), then release the
button.
f. If your CO Breath Sensor LED flashes green, tap Confirm on the screen to
complete the Bluetooth pairing process.
g. If your CO Breath Sensor is NOT flashing green, wait to select the Try Again
button and start again.
10.2 Getting Started
After successful pairing, you will be directed to the Getting Started page, where you
will watch the Breath Test Video Tutorial. This video provides instruction about how
to use your CO Breath Sensor to measure the amount of CO in your breath. You must
watch this video in order to continue further into the app.
After viewing the Breath Test Video Tutorial, you will go to an interactive tutorial
called YOUR Guided Breath Test (GBT). In YOUR GBT, you’ll learn how to submit a
breath sample by following interactive on-screen prompts.
Before using YOUR GBT, make sure your sensor is fully charged and in your hand, and
make sure the air temperature is not too cold or too hot (between 40oF and 90oF) so
that the sensor can fully detect when you start and stop blowing.
YOUR GBT will guide you through the steps and timing of taking a deep breath in,
holding it, and then blowing gently into the CO Breath Sensor.
a. The sensor and app determine if you have provided an adequate breath sample:
i. If yes, you will see a “success” screen with a smiley face; tap View Results
to view your results on the CO Log screen.
ii. If the submitted sample was not adequate, you will be asked to repeat
the Guided Breath Test. Reasons for inadequate breath sample include
blowing too soon, not long enough, or starting too late.
Adequate breath sample Inadequate breath sample
b. You may repeat the video tutorial or Guided Breath Test as often as you like by
going to the Help screen.

10.3 Submitting a Breath Sample
a. Insert a straw in the inlet of CO Breath Sensor.
b. Press and hold the button until you hear a beep and the LED starts flashing blue.
Take a deep breath in and hold it, and release the button. You will hold your
breath for 10 seconds.
NOTE: If you cannot hold your breath for a full 10 seconds, you may begin holding
your breath a few seconds after the first notification beep. In this case, you will
hold your breath for less than 10 seconds. Your breath CO (ppm) results may be
slightly lower if you do not hold your breath for the full 10 seconds.
c. After about 8 seconds, you will hear the first of 3 beeps to prepare you to blow
into the sensor.
d. Upon the third beep, gently blow into the straw and CO Breath Sensor for about
12 seconds or until you exhaust your entire breath.
e. After you stop blowing, the LED will flash either green or red.
Table 1. LED Light Indications After Breath Sample
LED Light
Description
Green
You provided an adequate breath sample and your data was
saved
Red
Your breath sample was not adequate, which may be due to:
1. You started blowing into the sensor before the third beep
(too early)
2. You waited too long after the third beep before starting to
blow (too late)
3. You did not blow long enough (minimum 6 seconds) (not
long enough)
f. The CO values and the date and time of the breath sample are saved on the CO
Breath Sensor until it syncs with your smartphone.
g. Syncing occurs automatically when the app is open and is able to connect to the
CO Breath Sensor (sensor is near-by, smartphone Bluetooth is on, sensor is
charged).
h. If you need to cancel a breath test at any time after initiating, hold down the
Breath Sensor button for 3 seconds (you will feel a slight pulse to confirm it
cancelled, and the LED will stop flashing).

13 Troubleshooting
If your paired CO Breath Sensor is not syncing with your smartphone, make sure your
CO Breath Sensor is fully charged and is near the smartphone.
If CO Breath Sensor is showing “Not Connected” in the CO Breath Sensor screen, make
sure that Bluetooth is activated on your phone and that the CO Breath Sensor is
charged. If paired, the CO Breath Sensor and application will sync automatically.
14 Frequently Asked Questions
What if I can’t hold my breath for the 10 seconds prior to blowing into the CO Breath
Sensor?
Try waiting a few seconds after being prompted to take a deep breath in. This
shortens your breath hold time by a few seconds. As a result, the CO ppm readings
may be lower than if you had held your breath for the full 10 seconds.
How can I review how to give a breath sample?
Go to the Help screen and repeat the video tutorial and/or Guided Breath Test.
