Engineering Scope
The development of low-power sports action sensors is oriented to the usage requirement of "sports equipment needs to record actions and upload training data". Collection, processing, communication and power supply are designed as one set of products. The project can start from new main board development, existing firmware modification or designated module integration. The development scope is confirmed based on the target function, existing foundation and delivery requirements.
Interfaces and Product Integration
Develop multi-axis acquisition, motion segmentation, basic features, caching, Bluetooth synchronization and device calibration interfaces.
Power Supply and State Scheduling
Collect continuous data and segment it when active, save the results when stationary, and synchronize when connected.
Data and System Integration
Clear connections and data formats around multi-axis sensors, equipment installation, sampling clocks and BLE, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form sampling firmware, action segmentation, cache format and training data transmission interface, focusing on verifying sampling frequency, data continuity, active and inactive switching and wireless throughput.
System Architecture and Operation
Collect continuous data and segment it when active, save the results when stationary, and synchronize when connected.
- Interface composition: multi-axis sensor, equipment installation, sampling clock and BLE.
- Work scheduling: Determine each status based on sampling, interaction and reception requirements, indicating which circuits continue to run.
- Exception handling: Define deadlines, bounded retries, and recovery behaviors for applicable communication, sensing, or execution tasks.
Design Conditions and Functional Limits
Action classification quality needs to be independently evaluated using representative samples.
Define power targets together with functional requirements. Battery-life estimates must specify the battery, temperature, operating cycle, event frequency and network conditions. Keep estimates separate from continuous-operation test results.

Explore the ScopeFrequently Asked Questions
Will the sensor lose its action start after entering the power saving state?+
It is necessary to measure the wake-up threshold, startup delay and sensor buffering capacity, and use actual actions to check the starting segment. You cannot select the mode based on static power consumption only.
Is it possible to develop only part of an existing product?+
Module development or power consumption optimization can be carried out according to the existing interface and modifiable range. For this product, you first need to check the multi-axis sensor, equipment installation, sampling clock and BLE, and then determine the scope of changes and regression.
How to determine the cost and period of this project?+
The evaluation is split based on deliverables such as sampling firmware, action segmentation, cache format, and training data transmission interface; the prototype materials, structure, platform, external tests, and new functions are listed separately, and quotations and nodes are formed after the requirements and interfaces are confirmed.
