Introduction
Thank you for purchasing the Smart Wireless Spirometer. We pride ourselves on producing high
quality products that meet with the demands of the busy classroom environment. If you have any
problems using this sensor, please read this documentation in full before contacting the Data Harvest
support team.
The Smart wireless Spirometer is a differential pressure transducer that interfaces to a pair of flow
heads to measure air flow rate. The sensor works by measuring pressure drop across a reference flow
resistance. An embedded microprocessor in the Spirometer converts the pressure readings into air flow
rate.
The user can choose to see data from the sensor as flow, volume, corrected volume, breathing rate or
change in pressure.
Alternatively the air flow data can be converted to volume using a simple function in the software after
data collection.
The Spirometer is supplied with a nose clip, 4 flow heads (one attached and three for test subjects) and
a circular guard for the ‘fixed’ flow head (to prevent it being used).
A flow head contains an antibacterial and antiviral filter to lessen the possibility of cross contamination
between subjects. Two flow heads are attached to the Spirometer during use; one is kept fixed in place
and the other is the test subject’s flow head. To minimise the danger of cross contamination, the flow
head used by the test subject is only for their own use and should be regarded as a ‘disposable’ item.
Note: The air flow rate measurement is only valid if two flow heads are fitted to the Spirometer
during use.
Replacement packs of 10 flow heads (Product No. 3269) and 5 nose clips (Product No. 3264) are
available from Data Harvest. Contact sales for further information.

Disclaimer
The Smart Wireless Spirometer is sold for the purpose of teaching and educational instruction. It is not
and has not been designed to be a diagnostic tool. The results are illustrative only; any information
gained from the use of this apparatus must not be used as the basis for any medical or clinical
diagnosis.
Read the instructions before use. Students should be supervised at all times.
Follow your local safety guidelines. It is the responsibility of the tutor to ensure
that individuals using this apparatus are healthy and have no history of
respiratory or cardiovascular problems. The students must be reassured about
the medical validity of the results. Respiratory tests can be challenging; limit the
number of tests in a session and take care that an individual is not overstressed
by the tests.
WE DO NOT RECOMMEND THE USE OF THIS SENSOR WITH INDIVIDUALS UNDER THE AGE
OF 10.
Overview
The Smart Wireless Spirometer is USB and Bluetooth compatible. Using Bluetooth, a sensor can
connect to mobile devices, tablets, laptops, and desktops.
The sensor has several ranges (flow (default), volume, adjusted volume, cyclic volume, breathing rate,
differential pressure). Any range can be selected on its own or selected alongside any other range.
The range required is set in the Devices icon of the EasySense2 software.
The Spirometer is used to measure changes in the volume of the inhaled and exhaled air. The total
volume of the lung can be calculated from various breathing processes and calculation of the
anatomical dead space.
The spirometer integrates the flow to produce volume (i.e. a flow of 1 l/s must produce 1 litre of volume
in one second and 2 litres of volume in 2 seconds etc.). Any value of the flow that differs from zero at
the start will become “integrated” into the volume and will be seen in the final data as a slope in the
data. A calibration function and Tare function are present to allow the no flow through of the Spirometer
become the zero base line to reduce this effect.
Additionally, the adjusted volume range uses mathematics to bring the data back to effective zero after
each breathing cycle.

Charging the Sensor
The Smart Wireless sensors are fitted with a rechargeable lithium-ion battery and can be charged via
the USB port. Use the supplied USB lead to connect the sensor either directly to a USB port on your
computer, a powered USB hub or a USB mains charger that outputs 5 V at 500 mA or more.
A full charge can take up to 4 hours.
Additional Information
Whenever the sensor is connected to the USB port on the computer or to a USB mains charger (output
5 V at 500 mA or more), it will automatically recharge the battery (LED status flashing white).
When connected to a computer, the computer should be turned on and not in sleep or standby mode,
as the battery may drain instead of charge.
The sensor will stay awake for 5 minutes when Bluetooth advertising (LED status flashing blue).
Lithium-ion batteries are ‘memory-free’ and prefer a partial rather than a full discharge. Constant partial
discharges with frequent recharges will not cause any harm. Frequent full discharges should be
avoided whenever possible. Ideally the sensor should be stored at about 40% or more charge.
The speed at which a lithium-ion battery will age is governed by both its storage temperature
(preferably less than 40 C) and state-of-charge.
