IMPROPER ꢀLEANING
• Avoid cleaning the sensor; however, if it must be cleaned use
isopropyl alcohol and dry the device thoroughly before use.
Cap the ports or connect housing to the ports before cleaning
the sensor with alcohol. Using alcohol may remove the text on
the sensor label; however, the label ID is hard coded inside the
sensor.
• Do not use III Tri-chloroethane, methylene chloride, methyl
pyrrolidone, or any oxidizing type acid such as formic acid.
• Do not use ultrasonic cleaning.

Absolute 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 necessary operate at

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 9 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 start-up 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’.
,
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 kΩ to limit the sink current to 2 mA. The typical value for SCL
and SDA pull-up resistors is 4.7 kΩ (this value depends on the bus capacitance and the bus speed).
