1. Features of Bluetooth GPS wireless module

Although the Bluetooth GPS receiver is more expensive, the advantage is self -evident. The biggest feature is to get rid of the restraint of the data cable.smart phone of the operating system.Another feature is that you can place the range of no more than 10 meters between the smartphone and the Bluetooth GPS between the two. This advantage is that the GPS receiver can be placed to the place where the satellite model is favored.In the location of the viewing, for example, NOKIA's latest GPS module provides lane, which can be hung on the chest for easy carrying.In addition, it is used for car navigation to use an external antenna. At this time, you should consider whether the GPS receiver provides an external antenna interface.

2. Disadvantages and advantages

1. Bluetooth GPS is very small, easy to carry, simple use.

2. Bluetooth GPS can be used with smartphones, laptops, and PDA palm computers.It's not troublesome to use!It is best to use genuine navigation maps. If you temporarily use pirated maps, there are currently intercity pirated maps, pirated map 3.05 pirated maps, Kailid navigation maps (intelligent use on mobile phones), Route 66 test version map, ozi, mapking......wait.For details, please go to the navigation map column to view.

3. Bluetooth GPS price is not expensive.The cheapest is only about 500 in China, and the best imported from Taiwan is about 880 yuan.There are nearly 20 types of Bluetooth GPS in the market for you to choose.

4. Choose Bluetooth GPS. When using smartphones and PDAs, it will no longer occupy the battery resources of the mobile phone or PDA alone, because the Bluetooth GPS is equipped with a battery, both equipped with vehicle chargers and 220V battery chargers.

Bluetooth GPS wireless template

1) Quick search: 32 XXX search at the same time, 20 channels.

2) High -tech GPS chip: Sirf Star III chip.

3) Quick TTFF: 200,000 valid decoders, which can ensure that fast TTFF can still operate when low signals.

4) Built -in Waas/EgNOS (optional hidden WAAS/EGNOS device) and DGPS high -precision positioning.

5) Quick heat start: built -in charging lithium batteries can provide sufficient power for fast heat start.

6) Support protocol NMEA-0183 v3. Data protocol.

7) Strengthening the computing method provides super navigation performance, which can be located in environments such as cities, canyons or trees.

8) No user initialization settings are required.

9) LED light number display status: LED's light display status allows users to judge the power status. When the power supply is connected, the LED light is on. When the GPS-6036 is located, the indicator light "On" is shining, no need to use it no longer need to use it.Other devices to distinguish.

[Hot and warm box purchase] Which type of cool and warm box is better to use the warm and warm box to buy guidelines

The advantages and disadvantages of semiconductor refrigeration (heat)

1. Volume and cost.No compressor is required, not only is the volume and small costs very low, but it can be reflected and heated.

2. Refrigeration temperature and heating temperature.Most of the minimum refrigeration temperature is about 6 degrees Celsius; the temperature difference between the minimum temperature and the environmental temperature does not exceed 20-25 degrees Celsius; the maximum heating temperature is about 65 degrees Celsius.

Large and medium vehicles can choose to compress the model Car refrigerator

1. RV, bus, and business models are larger. For large and medium -sized vehicles with larger compartment, if you need to be stronger, faster, and more constant, the refrigeration performance is required.The Car refrigerator is the first choice.

2. Power interface.Large and medium -sized vehicles are sufficient, and can even provide 220V standard power port and power output power above 500W.

3. Compressed models of car refrigerators usually have no heating function.

Don't ignore the thermal insulation and heating function

1. Thermal insulation effect.The cabinet of the car's warm and warm box is thick and good thermal insulation performance, and it should have good thermal insulation (cold) performance.

2. The heating function is more practical.In winter, many regions do not need to refrigerate (the trunk is an excellent "refrigerator"), but enjoying a hot food and drinks in the itinerary often become extravagant.The insulation and heating function of the car warm and warm box uses the place where it is displayed at this time.3. Heating is more efficient than cooling.Fortunately, the heating speed of the car warm and warm box is relatively faster and more efficient, and the temperature limit of the maximum 65 degrees Celsius is enough to meet daily needs.

The relationship between capacity, refrigeration speed and power

1. The larger the capacity, the slower the cooling (thermal).For example, for example: 60W power 4 -liter of mini warm and warm box. At the temperature of 28 degrees Celsius, the temperature in the box (empty box) can be reduced to 6 degrees Celsius in about 3 small, but if it is also 60W power 8 liters, if it is also 60W power 8 liters, 8 liters of power 8 litersThe cooling and warm box of capacity may take more than 6 hours to fall to 6 degrees Celsius.

2. The smaller the power, the slower the cooling (thermal).Play another less accurate analogy: a 60W power 4 -liter mini warm and warm box. If it is 3 hours of refrigeration to 6 degrees Celsius, if it is replaced by 30W power, this time may be extended to more than 6 hours (Little Mara Grandcar).

3. Cold and warm boxes with small capacity and high power.In order to ensure good refrigeration efficiency, under the premise of sufficient capacity, high -power, small -capacity warm and warm box may be the best choice.

Factors affecting cooling (thermal) efficiency

1. Environmental temperature.The higher the ambient temperature, the slower the cooling speed of the car in the car, and the faster the heating speed; vice versa.

2. The items to be stored.If a bottle of boiling water wants to refrigerate, the effect of putting in the car hot and warm box is not as effective as opening the bottle cap for a few hours; if it is a piece of ice, if you want to be discharged, the effect of putting in the car warm and warm box may be in the sun.The difference is not much different.

3. Pre -cold (hot) food and drink.In order to achieve rapid and efficient cooling or heating, it is necessary to put food that need to be refrigerated in advance in the home refrigerator in advance, or heat the food that needs heating in advance in the microwave oven, which can achieve faster, more efficient, more efficient, more efficient, more efficientConstant cooling or heating effect.

4. It is strongly recommended to use ice Bags or iced bottles of water to assist cold, which is more efficient and more constant.

The necessity of the car family dual -use warm and warm box

1. Innonal air is not that you can come.Many car owners complain that the cooling speed of the car warm and warm box is slow. It is known that a bottle of constant warm water is placed in the Car refrigerator for 1 hour and has not changed much.The slow cooling speed is indeed the embarrassment of the car warm and warm box, which is also the time when the advantages of the cool and cold box of the car family.Housewriters can be used on the car or connect to the ordinary power supply at home, which can be used at home. It can work almost in any place with a power supply to maximize the temperature loss and fluctuations caused by power interruption.

2. Use the car warm and warm box in the home environment.The working principle of the car warm and warm box is similar to that kind of refrigerated heat -made dual -use water dispenser. If necessary, you can use the car warm and warm box in the home environment through the power transferor, which makes the advantages of the dual -use of the car.Essence
