Development of Bluetooth tire pressure monitoring scheme
This scheme is a mature scheme in the collection of intelligent consumer electronics solutions. The program can test the sample chip in 7 days at the fastest. It is a tire pressure device that can connect the mobile phone app to detect the data in real time!
Development of Bluetooth tire pressure monitoring scheme
1、 Function
1. The signal is transmitted through Bluetooth 5.0 technology, and the mobile phone app detects the tire pressure, with high speed and low power consumption;
2. Five alarm functions: abnormal tire pressure, air leakage alarm, low power alarm, high tire temperature alarm, sensor failure alarm;
3. Bluetooth 5.0 high-speed connection, high accuracy and stability, and rapid sensing of abnormalities;
4. IP67 waterproof, dust-proof, high temperature proof, all-weather escort for you;
5. Large screen display, real-time detection, abnormal and accurate alarm;
6. Compact body and simple installation;
7. Then magnetic attraction charging technology is used to eliminate the form of plug-in charging;
8. Imported chips, accurate data feedback, timing and prevention of emergencies;
9. Applicable to a variety of models.
2、 Bluetooth chip selection
The Bluetooth Solution Development Engineer analyzed the commonly used Bluetooth tire pressure monitoring development solutions in the market, and assessed that the ac6321a4 qfn32 model of Jerry ble Bluetooth chip series can be used as the main control chip.
3、 Working principle
There are three types of Bluetooth tire pressure monitor: direct, indirect and two types of tire pressure. The principle of indirect type is that when the pressure drop of the tire is the lowest, the difference in the rotational speed of the wheel will achieve the purpose of monitoring. The direct type is to monitor the air pressure of the tire by using the sensors installed on each wheel, and the tire that is abnormal will display the problem.
The above is the development content of the Bluetooth tire pressure monitoring scheme shared by the Bluetooth scheme development engineers.
