Engineering Scope
The development of low-power greenhouse environmental collection nodes is oriented to the usage requirement of "the greenhouse needs to add wireless environmental measurement points", 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 temperature, humidity, light and other sensor interfaces, sampling scheduling, networking, parameter distribution and exception recording.
Power Supply and State Scheduling
Sampling is scheduled according to the stabilization time of each sensor, the records are aggregated and uploaded, and period configuration is accepted.
Data and System Integration
Clarify connections and data formats around temperature, humidity, light and optional environmental sensors and node networking interfaces, and define recording, transmission, confirmation and abnormal status.
Prototypes, Testing and Deliverables
Form collection firmware, node configuration, data fields and network association records, focusing on verifying sensor combination, data refresh delay, loss of connection and reconnection, and sensor stabilization time.
System Architecture and Operation
Sampling is scheduled according to the stabilization time of each sensor, the records are aggregated and uploaded, and period configuration is accepted.
- Interface composition: temperature, humidity, lighting and optional environmental sensors, node networking 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
The power budget should be recalculated when adding sensors that require preheating or continuous operation.
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.

Can different sensors share a sampling period?+
Unified scheduling can be performed when the business permits, but the startup, stability, and sampling conditions of each sensor should be met separately, and slow sensors cannot be allowed to block other tasks for a long 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 temperature, humidity, lighting, optional environmental sensors, and node networking interfaces, and then determine the scope of changes and regressions.
How to determine the cost and period of this project?+
The evaluation is split based on the delivery items such as collection firmware, node configuration, data fields and network debugging records; the prototype materials, structure, platform, external tests and new functions are listed separately, and the quotation and milestones are formed after the requirements and interfaces are confirmed.
