Zephyr Heart Rate Monitor
Go Up to ThingConnect Devices
Zephyr Heart Rate Monitor is a heart rate monitor device from Zephyr that comes with a strap.
Zephyr Heart Rate Monitor has a LED that blinks every 3 seconds to indicate its connection status:
- 3 times: Zephyr Heart Rate Monitor is connected to another device.
- 1 time: Zephyr Heart Rate Monitor is available for connection.
Use the TZephyrHeartRateMonitor
component to communicate with the Zephyr Heart Rate Monitor.

Custom Data Types
The Zephyr Heart Rate Monitor defines its custom data types in the following unit:
- Iot.Device.ZephyrHeartRateMonitorTypes
Custom Zephyr Measurement
The TZephyrMeasurement
type returns specific activity and peak acceleration data from the Zephyr Heart Rate Monitor.
ActivityFlag
: Boolean value for showing the presence of the optional Activity field.- 0: Activity Field not included.
- 1: Activity Field included.
PeakAccelerationFlag
: Boolean value for showing the presence of the optional PeakAcceleration field.- 0: Peak Acceleration Field not included.
- 1: Peak Acceleration Field included.
ActivityField
: The current activity level. Valid range is from0…16
, with 0.01 unit resolution.PeakAcceleration
: The highest g-force measured in the last measurement period of 1 second, measured ing
. Valid range is from0…16
, with 0.01 unit resolution.
Custom Zephyr Test Mode
The TZephyrTestMode
record type returns test mode data to the client device from the Zephyr Heart Rate Monitor. Test mode data includes accelerometer data, ECG, and Flash data.
Value
: Raw array of bytes received from the device.- Flash data information from the device.
FlashMemCap
(byte [1]): Flash memory capacity. Its value is0x14
.FlashMemType
(byte [2]): Flash memory type. Its value is0x71
.FlashManId
(byte [3]): Flash manufacturer ID. Its value is0x20
.
EcgMaximum
(bytes [4-5]): Highest sample over the last 1 second period. Valid range is from0-1023
.EcgMinimum
(bytes [6-7]): Lowest sample over the last 1 second period. Valid range is from0-1023
.
- Flash data information from the device.
- Accelerometer data: Each axis in accelerometer data is averaged over the last 1 second period to remove noise/vibrations.
AccelZ
(bytes [7-8]): Valid range is from-2048 ... +2047
, with 1G equal to 83.AccelY
(bytes [9-10]): Valid range is from-2048 ... +2047
, with 1G equal to 83.AccelZ
(bytes [11-12]): Valid range is from-2048 ... +2047
, with 1G equal to 83.
- Accelerometer data: Each axis in accelerometer data is averaged over the last 1 second period to remove noise/vibrations.
