Routine inspection, cleaning, and system checks to keep 3D-PAWS stations operating reliably and producing high-quality data.
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.
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
remove debris (leaves, dirt, insects)
ensure tipping mechanism moves freely
verify level installation
confirm free rotation (no binding)
inspect for physical damage or debris
check mounting stability
clean surfaces if dirty
ensure ventilation openings are clear
verify no insect nesting
confirm good soil contact
inspect for disturbance or exposure
check cable integrity
confirm data transmission is active
verify sensor readings are updating
check for unexpected or unrealistic values
monitor battery voltage trends
Over time, components may degrade or fail. Plan for:
sensor replacement
battery replacement
cable wear and repair
enclosure maintenance
Batteries
2–3 years
Sensors
3–5 years
Cables
3–5 years
3D-printed parts
5+ years
→ See Sensor Lifecycle Planning
Record maintenance activities:
date and conditions
work performed
issues observed
parts replaced
→ See Station Metadata and Asset Management
The following issues may develop over time and can often be identified during routine maintenance:
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
Regular maintenance improves system reliability, extends station lifespan, and ensures consistent data quality.
