Development Scope
Device and interface access
Connect soil moisture and temperature probes at different depths, and design sensor power supply, stable waiting for sampling, low-power main controller and protection interfaces.
Product business functions
Develop multi-depth sensor acquisition, power supply control, scheduled wake-up, batch upload, network disconnection caching and sampling parameter management.
Platform and data connection
Combined with the business link of sensor → local collection and control → 4G → remote configuration and alarm → job record, the device identity, data fields, update time, abnormal status and result confirmation method are defined.
Exception handling and operational constraints
Probe output, burial depth and calibration conditions affect data interpretation; battery life needs to be combined with network access time, reporting frequency and environmental measurements.
Data and Operational Workflow
Scheduled wake-up → Probe power-on and stable → Hierarchical sampling → Local recording → 4G batch upload → Sleep.
The device side, communication side and platform side retain necessary status and logs respectively. Project integration testing is checked with actual equipment data and execution results, and network connection status and business completion status are recorded separately.
Project Inputs
- Existing device models, interface and wiring diagrams, licensing agreements, data samples and available codes.
- Business process and parameters: probe burial depth, sampling waiting time, batch upload and network-free retry strategy.
- Target location, operator, SIM/APN, power supply, installation method and equipment size.
- Existing platform interfaces, user roles, development modules, number of prototypes and planned nodes.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| product realization | Hardware design data, prototypes or existing equipment modification data involved in the project, as well as corresponding firmware and interfaces | Check depth number, probe field and dimension. |
| Business integration testing | Data fields, status definitions, platform adaptation procedures and business integration testing records | Measure the complete wake sample upload cycle. |
| Version and test data | Target hardware and software versions, build or deployment instructions, parameter configurations and test logs | Verify the no-network retry limit and low battery degradation. |
First confirm the scope and key functions, then complete prototype or software development, system integration testing and stage acceptance. The acceptance conditions list the prototype, version, environment, duration and passing threshold; source code, design documents, third-party licenses, materials, traffic, cloud resources and on-site work are agreed separately.
Frequently Asked Questions
Can the sampling frequency and upload frequency be different?+
You can sample locally according to a shorter period and upload in batches according to a longer period. It is necessary to clarify the cache capacity, whether alarms are uploaded immediately, and the confirmation and retransmission rules after batch failure.
Can I entrust only part of the functions of the soil moisture monitoring terminal?+
The device interface, terminal program, 4G communication and platform integration testing can be split based on the existing R&D foundation. Please provide existing data and target boundaries, first check "probe burial depth, sampling waiting time, batch upload and network-free retry strategy", and then clarify the deliverables and interface responsibilities of each module.
How are costs and cycle time assessed?+
Split the workload based on target devices, interfaces, existing data, and verification criteria. This project focuses on checking the probe burial depth, sampling waiting time, batch upload and network-free retry strategy; when prototypes, on-site integration testing or third-party platform cooperation are required, the corresponding costs, prerequisites and nodes will be listed separately.
