# Station Maintenance

### Overview

Routine maintenance ensures that 3D-PAWS stations continue to operate reliably and produce high-quality data over time.

Maintenance includes inspection, cleaning, system checks, and periodic component replacement.

***

### Routine Maintenance

Perform regular inspections:

* inspect sensors and mounts for damage
* verify all cables and connections are secure
* clean the sensors and solar panel (remove dust and debris)
* check battery condition and voltage
* ensure the enclosure is sealed and protected from moisture

***

### Sensor Maintenance

#### Rain Gauge

* remove debris (leaves, dirt, insects)
* ensure tipping mechanism moves freely
* verify level installation

***

#### Wind Sensors

* confirm free rotation (no binding)
* inspect for physical damage or debris
* check mounting stability

***

#### Radiation Shield (Temperature / Humidity / Pressure)

* clean surfaces if dirty
* ensure ventilation openings are clear
* verify no insect nesting

***

#### Soil Sensors (if installed)

* confirm good soil contact
* inspect for disturbance or exposure
* check cable integrity

***

### System Checks

* confirm data transmission is active
* verify sensor readings are updating
* check for unexpected or unrealistic values
* monitor battery voltage trends

***

### Lifecycle Planning

Over time, components may degrade or fail. Plan for:

* sensor replacement
* battery replacement
* cable wear and repair
* enclosure maintenance

| Component        | Typical Lifespan |
| ---------------- | ---------------- |
| Batteries        | 2–3 years        |
| Sensors          | 3–5 years        |
| Cables           | 3–5 years        |
| 3D-printed parts | 5+ years         |

### Documentation

Record maintenance activities:

* date and conditions
* work performed
* issues observed
* parts replaced

→ See [**Station Metadata**](https://3dpaws.comet.ucar.edu/deploying-3d-paws/station-metadata) and [**Asset Management**](https://3dpaws.comet.ucar.edu/station-maintenance-and-operations/asset-management)

### Common Maintenance Issues

The following issues may develop over time and can often be identified during routine maintenance:

| ❌ Issue              | ✅ Action                                |
| -------------------- | --------------------------------------- |
| No data transmission | Check power and connectivity            |
| Incorrect readings   | Inspect sensors and siting              |
| Intermittent data    | Check wiring and connections            |
| Physical damage      | Repair or replace components            |
| Low battery          | Check solar input and replace if needed |

***

### Summary

Regular maintenance improves system reliability, extends station lifespan, and ensures consistent data quality.
