Let me talk about my situation. I have a normal figure in my early thirties. I occasionally run 5 kilometers and 10 kilometers with my friends. Half horses can also finish. For running, I always use the sun for three days, and the results are not improved. It can only be done. Songtuo M5 is an early start, but we all know that the use of trouble heart rate belt, M5 occasionally exhausted, to reverse the heart rate with the battery to watch the success of the match, so whim has a smart hand with heart rate function The idea of ​​the ring, a button in his hand when running, will be able to go out with a gust of wind.
Personal requirements for smart bracelets are single, not counting anything, GPS, sleep reminders, sedentary reminders, and the like. I only want to raise my hand when I run, and I know how much my heart rate is now. Careless running away), especially when running half a horse, can control the pace through the heart rate.
First consider the domestic goods (actually no money), millet bracelet 2, and customer service consulting, customer service reply is to use with the test, indicating that the white point is that when you run to lift his left hand, and then move the right hand over, click, Wait a few seconds (5 seconds?10 seconds?) to see the current heart rate. Does not meet my needs, do not consider.
Later, I saw the Happy Heart Bracelet 2, which is known to be very aggressive in heart rate monitoring and is monitored continuously for 24 hours. After careful communication with the customer service, the customer service indicated that the heart rate data will float between ±5, and the real-time heart rate can be seen immediately by raising one hand. The error can be accepted. I feel that this is exactly what I do for the runners, so I immediately started with one of Tmall's flagship stores.

Lynx's bags
Outside the box, no evaluation, because it is the buyer's ring, it is not to buy a box.
The instructions are in it. It is actually very simple and will be used after downloading the APP.

The next morning when I got the bracelet, I got up and ran 5 kilometers in the morning. I used the å’•å’š APP to take a photographic data every other kilometer during the running. In addition, I added the data of the beginning, the end, and the 2.5 kilometers. There were 8 sets of data. As shown below. PS: Songtuo watches are worn very loosely and do not affect blood flow.

Data table
1. This analysis is based on the fact that everyone is relatively recognized. It is more accurate to use the heart rate to measure the heart rate.
2. When resting and relatively low-intensity exercise (such as simple warm-ups such as walking and waving a few arms), the error measured by the wristband and heart rate band is very small, and basically it is also in the music heart nominal Within the range of ±5. See measurement point 0 and end data.
3. When jogging, the error starts to increase, with an error range of -9 to -14. See measuring point 1, 2, 3 data.
4. When performing continuous high-intensity exercise, the error becomes unacceptable. At the acceleration of the last kilometer, the blood was concentrated on his legs and his hands felt cold. However, the data measured at the wristband did not increase with the heart rate, but dropped. Do not give up the last kilometer of the pace, already tired of the dog, can not run. See data at measurement point 5 and measurement points 2.5 and 4
5, happy heart customer service said, the measurement mechanism of the hand ring is photoplethysmography (PPG), heart contraction, increased blood flow at the wrist, blood absorption of green light increases, reflected green light decreases; and diastolic, absorb green light decreases The reflected green light increases; the wristband sensor calculates the heart rate by reflecting the green light frequency. But in the case of high-intensity exercise, the heart rate has actually accelerated, but the blood has flowed more toward the legs, and the bracelet at the wrist still faithfully reflects the heart rate data through the blood flow at the wrist. As a result, the heart rate error during exercise is measured. This is an error caused by the measurement mechanism and the measurement position. It should be irreparable. I do not know what kind of situation is the use of high-end cameras such as Garmin. Welcome to discuss it.
to sum upIt doesn't matter if it's good or bad, it's only right.
Finally put a photo of two guys
The wire harness simplifies the building of these larger components by integrating the wiring into a single unit, or several units, for [drop-in" installation. By binding the many wires, cables, and subassemblies into a harness, the OEM or installer only has one component to install. In addition, a wire harness allows the completed assembly to be better secured against the effects of abrasion and vibration, and by constricting the wires into a non-flexing bundle, usage of space is optimized.
