There are different sensors that you can use with our iTHRVE apps.
Sensors for iTHRVE stress management
This HRV app has been designed to work with different sensors:
• iOS Camera (on your iPhone)
• iOS Bluetooth Fingertip Pulse Oximeter
Working with the latest update of the Apps – from January 2017
PPG Mobile Phone Heart Rate Monitor Finger clip Sensor
• Ear clip Bluetooth sensor
Mobile Phone Heart Rate Monitor with Ear Clip
Mobile Phone Heart Rate Monitor with Ear Clip Sensor
• Polar chest strap
Polar H7 Bluetooth Chest Strap
WATCH How to use the chest strap for doing overnight or long-term HRV recordings
All of these sensors can be used for short recording (less than 30 minutes): mainly designed for coherence and breath training.
Long recording (up to 8 hours and a half), can only be done with the use of a Polar chest strap or a compatible Bluetooth chest strap device.
The pressure wave (related to the Mayer wave or Craniosacral wave) can only be displayed with the Berry finger sensor.
The light sensors devices (Berry finger sensor, the earclip sensor and the iOS camera) are very sensitive to movements of the sensor: they need you to be quite still- when used to achieve a good acquisition of data.
