Today’s post is about a pair of wireless (Bluetooth / ANT+) sensors from CooSpo. Consider two models: the H6M chest pulse sensor and the BK467 universal cadence/speed sensor. Despite the fact that the bike computer appears in the name, these sensors can be used in sports training and with a smartphone via Bluetooth.

Specifications

Let’s start with the CooSpo BK467 combined cadence/speed sensor:

• Wireless interfaces: Bluetooth / ANT+
• Maximum values: 120 km/h speed, 300 rpm cadence
• Material: ABS plastic
• Protection: IP67
• Operating temperature: -10…+50°C
• Power supply: CR2032 220 mAh
• Working time: 320 h
• Dimensions: 41x34x10 mm
• Weight: 9.5 g

Now the heart rate monitor (cardiac sensor) CooSpo H6M:

• Wireless interfaces: Bluetooth / ANT+
• Range: 10/6m
• Protection: IP67
• Pulse range: 30-240 bpm
• Power supply: CR2032 220 mAh
• Working time: 300 h
• Dimensions: 60×33.8×12.2 mm
• Strap: 65-95cm adjustment
• Weight (without strap): 15 g.

Packing and scope of delivery

The BK467 sensor is supplied in a small cardboard box with a window. Two scenarios for its use are immediately indicated on the box: measuring speed or counting cadence (pedaling frequency of a bicycle).

The sensor is made in China.

The package includes everything you need to mount the sensor on the wheel hub (for measuring speed) and on the crank (for calculating cadence).

• The sensor itself with a CR2032 battery installed
• Three pairs of rubber rings for fastening
• Two rubber pads for mounting on the bushing or on the connecting rod
• User Manual (English)

Now the packaging of the CooSpo H6M heart rate monitor is an elongated box with color printing.

Protective cardboard insert inside.

Standard delivery set for chest heart rate monitors:

• Heart rate monitor with CR2032 battery installed
• Adjustable nylon strap
• User guide

The manual provides visual guidelines for the correct placement of the transducer on the chest.

Appearance

Consider the exterior of the sensors in the same sequence, first BK467.

The sensor is made in a square plastic case, on the sides of the lugs to hold the rubber mounting rings. The battery compartment opens with a coin, and with a rubber ring seal, a battery from the Maxell brand. Switching operating modes is implemented here – by rearranging the battery (although a microswitch is more convenient). If, when changing the battery, the red diode on the front lights up – it works as a speed counter, the blue one – cadence.

For mounting, rubber gaskets are used (fixed on the sensor body, the gasket is concave for the sleeve) and rubber rings of different diameters.

Let’s move on to the CooSpo H6M heart rate monitor.

Sensor housing with smooth lines, brand engraved. The battery compartment is protected from moisture and sweat, but there is no mention of use in the pool. The sensor is fastened with tight rivets to the belt (observe the marked sides for greater accuracy), the belt can be washed separately after training.

Sensor electrodes are placed on the inside of the belt, they are made of thin conductive rubber, with the help of which heart rate data is obtained, this method is more accurate than optical sensors in smart watches and fitness bracelets, especially at high heart rate values.

The width of the belt is 30 cm. It is very elastic and pleasant to the body. It can be adjusted to different chest coverage, and the plastic clasp is no hassle.

Exploitation

To get started, you need to install each sensor.

Let’s start with BK467, I need it as a cadence sensor. I mount it on the connecting rod so that it does not cling to the frame. Rubber rings are great, of course, but I have already lost two sensors, so I’ll add electrical tape for insurance, although not orthodox blue.

The sensor is activated only during operation to save the battery, rotate the pedal and find it on the bike computer (here iGPSPORT iGS618) or smartphone. The manufacturer promises 320 hours of operation from a standard 2032 battery, which is about a year of use on a bicycle.

The pros and cons of GPS bike computers compared to a smartphone for a cyclist are discussed here .

Further, during the trip, we monitor the level of cadence (in the region of 60-100 rpm for training), this reduces the load on the knees, optimizes the energy consumption of the trip, and increases endurance.

The pulse sensor is hung on the naked body on the chest, so that it would work immediately, you need to moisten the electrodes with water to increase conductivity. I will not show it on myself from aesthetic positions, but the sensor holds well, does not slip even with active movements.

Also, we find the sensor with a bike computer and look at the pulse and pulse zones during the trip / training. The level is about 220 beats minus your age, and then look at the state. For runners, the heart rate monitor is no less useful than for cyclists. I repeat, such a chest sensor gives greater accuracy on the power pulse than the optical one in fitness bracelets.

Both sensors support the ANT+/Bluetooth multi-protocol system, which means that they can work both with smartwatches and GPS bike computers, as well as with mobile applications on a smartphone (CoospoRide, Wahoo Fitness, Adidas run, Peloton, Zwift, Strava, etc.)

Conclusion

The CooSpo BK467 + H6M sensor kit will be a good help for competent cyclist training. Sensors are affordable, relatively branded, like Garmin or Suunto. At the same time, they are accurate, with stable communication and universal protocols.
