FEATURES
• Fast response time (1 ms) allows the customer’s application
to respond quickly to a change in airflow, important in
critical medical (e.g., anesthesia) and industrial (e.g., fume
hood) applications.
• High stability reduces errors due to thermal effects and
null shift, providing accurate readings over time and often
eliminating the need for system calibration after PCB mount
and periodically over time.
• High sensitivity at very low flows provides a fast response
time at the onset or cessation of flow.
• High 12-bit resolution increases the ability to sense small
airflow changes, allowing customers to more precisely
control their application.
• Wide airflow range: The industry’s broadest airflow range
measures mass flow with standard flow ranges of 0 to10,
0 to 15, 0 to 20, 0 to 50, 0 to 100, 0 to 200 and 0 SLPM to
300 SLPM, or custom flow ranges, increasing the options to
integrate the sensor into the application.
• Choice of port styles: Manifold mount, 22 mm OD tapered
male fitting, and G 3/8 female threaded fitting provide
flexibility to choose the pneumatic connection that is best
for the customer’s application.
DESCRIPTION
Honeywell Zephyr™ HAF Series sensors provide a digital
interface for reading airflow over specified full-scale flow and
compensated temperature ranges. The thermally isolated
heater and temperature sensing elements help these sensors
provide a fast response to air or gas flow. Zephyr sensors are
designed to measure mass flow of air and other non-corrosive
gases. Standard flow ranges are 10 SLPM, 15 SLPM, 20
SLPM, 50 SLPM, 100 SLPM, 200 SLPM and 300 SLPM,
with custom flow ranges available. The sensors are fully
calibrated and temperature compensated with an onboard
Application Specific Integrated Circuit (ASIC). The HAF Series
>10 SLPM is compensated over the calibrated temperature
range of 0°C to 50°C [32°F to 122°F]. The state-of-the-art
ASIC-based compensation provides digital (I2C) outputs with
a response time of 1 ms. These sensors operate on the heat
transfer principle to measure mass airflow. They consist of
a microbridge Microelectronic and Microelectromechanical
System (MEMS) with temperature-sensitive resistors
deposited with thin films of platinum and silicon nitride.
The MEMS sensing die is located in a precise and carefully
designed airflow channel to provide repeatable response to
flow. Zephyr sensors provide the customer with enhanced
reliability, high accuracy, repeatable measurements and the
ability to customize sensor options to meet many specific
application needs. The combination of rugged housings with
a stable substrate makes these products extremely robust.
They are designed and manufactured according to ISO 9001
standards.
• Linear output provides a more intuitive sensor signal than
the raw output of basic airflow sensors, which can help
reduce production costs, design, and implementation time.
• Wide supply voltage range (3 Vdc to 10 Vdc) provides a
flexible regulated power circuit which allows the designer the
flexibility to choose the supply voltage that works best in the
system.
• ASIC-based I2C digital output simplifies integration
to microprocessors or microcontrollers, reducing PCB
complexity and component count.
• RoHS-compliant materials Meet Directive 2002/95/EC.
POTENTIAL APPLICATIONS
• Medical: Anesthesia delivery machines, ventilators,
ventricular assist devices (heart pumps), spirometers,
laparoscopy
• Industrial: Analytic instrumentation (spectrometry,
chromatrography), air-to-fuel ratio, fuel cells, fume hoods,
gas leak detection, process control gas monitoring, vacuum
pump monitoring
PORTFOLIO
The Honeywell Zephyr Digital Airflow Sensors join an
extensive line of airflow sensors for potential use in medical,
industrial, and consumer applications.
VALUE TO CUSTOMERS
• Precise measurement: The industry’s smallest Total Error
Band, fast response time, and high accuracy provide precise
measurement and high performance in the customer’s
application.
• Saves time: Configurable and customizable with a choice of
port styles simplifies design and reduces production time.
• Cost-effective: Reduces printed circuit board (PCB) size and
overall design and production costs.

Ideal for use in demanding applications that require high

Honeywell specifies TEB, the most comprehensive, clear,
and meaningful measurement that provides the sensor’s
true accuracy (see Figure 1). TEB allows for precise airflow
measurement, often ideal for demanding applications with high
accuracy requirements for precise airflow measurement.

1Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and
mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will
the device necessarily operate at absolute maximum ratings.
2Digital I/O pins are diode protected at this voltage up to 2 mA. Digital bus voltage may exceed this value if the maximum digital bus current is
limited to 2 mA or less. The maximum bus current is generally determined by the bus pull-up resistors

Digital Interface
For additional details on the use of Zephyr with digital output see the Technical Note “I2C Communications with Honeywell
Digital Airflow Sensors”.
The sensor uses the I2C standard for digital communication with a slave address specified in the Nomenclature and Order Guide
in Figure 2. Following sensor power-up, each of the first two read sequences shown in Figure 7 will respond with 2 bytes of the
unique 4-byte Serial Number. The first read after power-up will respond with the two most significant bytes of the Serial Number,
while the second read will respond with the two least significant bytes of the Serial Number. For reliable performance, allow
sensor to be powered for the sensor startup time before performing the first read, then allow a 10 ms command response time
before performing the second read.

After the power-up read sequence described above, the sensor will respond to each I2C read request with a 16-bit (2 byte)
digital flow reading. Read requests taken faster than the Response Time (1 ms) are not guaranteed to return fresh data. The first
two bits of each flow reading will be ‘00’, while non-flow responses (such as error and status codes) will begin with ‘11’. There
are several user commands available as shown in Table 8. Following an I2C write sequence of a user command, the sensor will
respond to the next I2C read request with a 16-bit response. Possible responses to user commands can be seen in Table 9.

The maximum sink current on SCL or SDA is 2 mA. Therefore, if the pull-up resistors are biased by VDD, and if VDD reaches
the maximum supply voltage of 6 V, then the pull-up resistors for SCL and SDA must be greater than 3.0 kOhm to limit the sink
current to 2 mA. The typical value for SCL and SDA pull-up resistors is 4.7 kOhm (this value depends on the bus capacitance and
the bus speed).
