Product features of STP-128
General
 HR001 is fully compliance with Bluetooth v4.O(Low energy)'s Heart Rate Profile(Revision

V10roo), so it can communicate with iPhone 4S and other devices which supports Bluetooth v4.0.

Noise Filtering
1. HR001 will filter the input pulse if the frequencty is over 4Hz
2. Have better performance subject to motion artifact during exercise

Good Stability in low and high temperature
1.The carrier frequency is divided from Bluetooth low energy IC, so it can keep good frequency

stability agAInst temperature variation.
2.The tranmission frequency is  ranged from 2.402GHz to 2.480GHz at -10°C to 60 °C, and theoperating voltage is ranged from 2.4V to 3.6V.

Low Power Consumption
1.The BATtery lifetime is up to 22 months @ 1 hour heart rate measurement per day.

Connection and Miscellaneous information
1. Heart rate data refresh rate is 2 second
2. If no heart rate signal is detected for 3 minutes, the HR001 goes to standy mode.
