Engineering Scope
The development of low-power wireless temperature collectors is oriented to the use requirement of "dispersed temperature measurement on bearings, cabinets and equipment surfaces". 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 probe interface, periodic temperature measurement, abnormal reporting, wireless transmission, battery detection and equipment configuration.
Power Supply and State Scheduling
Enable the probe periodically and wait for stabilization before sampling; when the temperature exceeds the limit, the event is recorded and reported as configured.
Data and System Integration
Clarify the connection and data format around the temperature probe interface, sensor data format, measuring point installation and thermal contact method, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form the probe driver, measurement cycle configuration, temperature and timestamp data model, focusing on verifying the sensor startup time, sampling cycle, reporting frequency and average current of the complete device.
System Architecture and Operation
Enable the probe periodically and wait for stabilization before sampling; when the temperature exceeds the limit, the event is recorded and reported as configured.
- Interface composition: temperature probe interface, sensor data format, measuring point installation and thermal contact method.
- 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
Temperature measurement error is determined by a combination of probe, installation, and complete device testing.
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
Can the probe be powered on before each sampling?+
The start-up and stabilization times should be confirmed first, and the actual energy of continuous operation and periodic power supply should be compared; the temperature change between the two measurements also needs to be included in the sampling requirements.
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 temperature probe interface, sensor data format, measuring point installation and thermal contact method, 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 probe driver, measurement cycle configuration, temperature and timestamp data model; 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.
