Guide: how to clean your connected weather station for clean data ?

Oct 24, 2025 • 3 min read

Connected weather stations have become essential allies for precision farming, optimising interventions and monitoring agroclimatic risks.

But to guarantee reliable data, it is essential to ensure proper installation... and regular maintenance!

In this article, discover:

why maintenance is essential
the risks involved if you don't do it
how to properly clean your station (rain gauge, anemometer, sensors)
the new ‘Station Health’ feature available in the Sencrop app

Why maintain your weather station?

💡

Because a clean, properly installed station = reliable measurements for better daily agronomic decisions.

🍂 Prevent the accumulation of leaves, insects and spider webs

The rain gauge is particularly sensitive:

dead leaves can block the entrance to the collector
insects and webs can prevent the tipping bucket from tilting properly

The anemometer can also be blocked by spider webs.

👉 What are the potential impacts if nothing is done:

underestimated rainfall totals
a ‘zero’ wind speed when there is actually wind
inaccurate local forecasts
incorrect alerts

Here are some photos and testimonials from our users:

🌿 Avoid data distorted by vegetation

Over time, vegetation can:

grow around your station
interfere with air flow
clog the rain gauge with dead leaves, for example
or create unwanted shade for the sensors

👉 What are the potential impacts if nothing is done:

underestimation or overestimation of rainfall
inaccurate temperature readings
less reliable risk models (diseases, irrigation, frost, etc.)

📌 Reminder: your station must be kept away from obstacles such as trees or buildings.

🪫 Anticipate the end of battery life

Like all electronic equipment, batteries eventually wear out. Sencrop supports you with a dedicated banner in the application to warn you when this happens. Just follow the instructions in good time!

👉 What could happen if nothing is done:

interruptions in data transmission
gaps in historical data
disruption to agronomic models

💡

Good news: you can order a battery directly from the application

How do I maintain my weather station?

To maintain accurate readings, it is recommended that you clean your weather station at least every three months. For detailed instructions on cleaning your station, see our FAQ, which includes step-by-step guides for cleaning the different types of sensors we offer (rain gauge, anemometer, humidity sensor, etc.).

In a few lines:

💧 Clean the rain gauge

Remove leaves, insects, dust
Clean the grid with warm water
Check that the tipping bucket moves freely

🌬️ Clean the anemometer

Remove webs and insects
Check that the cups rotate freely

🌡️ Clean the temperature and humidity sensors

Dust the shelter
Check that no insects are lodged there

Maintenance made easier by the Sencrop app

To provide you with even better support, the Sencrop app now includes a station health dashboard, accessible in the ‘Health dashboard’ tab.

This table allows you to:

Automatically monitor the cleanliness of the rain gauge. You will then receive a cleaning alert. For example, the application detects:
- a rain gauge that may be clogged
- abnormal tilts suggesting an obstruction
- inconsistent deviations from neighbouring stations
Be notified if the anemometer shows signs of blockage
Receive regular maintenance reminders - Because the best cleaning is the one you don't forget!
Be alerted in case of low battery - To avoid any data loss.

👉 This feature is available on all Sencrop 4G stations.

🎉 Your station is clean, operational, and automatically monitored!

A well-maintained station means reliable data, greater agronomic accuracy, peace of mind every day, fewer unexpected breakdowns, and now... automatic monitoring thanks to Sencrop station health.

Have a great season with optimised weather data! 🌱🌦️
