Engineering Scope
The development of low-power wireless pressure monitoring terminals is oriented to the use requirement of "pipeline and gas line pressure measurement points without nearby power supply", and the 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 pressure sensor power supply, analog front end, ADC acquisition, threshold events, calibration parameter storage and data reporting.
Power Supply and State Scheduling
Turn on the incentive and front-end, complete stabilization and conversion, cache and send after judging that the limit is exceeded.
Data and System Integration
Define the connection and data format around the pressure bridge or digital probe, excitation voltage, analog range and ADC interface, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
The simulation front-end data, sampling firmware, calibration parameter structure and pressure step test records are formed, focusing on verifying the sensor warm-up and stabilization time, reading deviation after switch power supply, and emission peak voltage drop.
System Architecture and Operation
Turn on the incentive and front-end, complete stabilization and conversion, cache and send after judging that the limit is exceeded.
- Interface composition: pressure bridge or digital probe, excitation voltage, analog range and ADC interface.
- 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
Pressure accuracy, overload and process suitability are determined based on the target sensor and installation conditions.
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.

Will intermittent power affect pressure readings?+
May affect zero point and first stable reading. It is necessary to compare the results before and after power supply switching under conditions of temperature and pressure changes, and then determine the waiting time.
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 pressure bridge or digital probe, excitation voltage, analog range and ADC interface, and then determine the modification and regression testing scope.
How to determine the cost and period of this project?+
The evaluation is split based on deliverables such as simulation front-end data, sampling firmware, calibration parameter structure, and pressure step test records; 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.
