Making a Climate Station at SparkFun HQ – Information

Take a look at our newest venture! We mounted our SparkFun Arduino IoT Climate Station to the roof at SparkFun HQ.




Have you ever ever wished to create your personal IoT climate station? This venture demonstrates how one can create a climate station monitored with Arduino Cloud.

Undertaking Concerns

Earlier than continuing with this venture, there are numerous issues to issue into your design decisions. The next are a number of examples, however not the extent of the components that will have an effect on your climate station.

  • Soil Moisture
    • On this venture, we won’t be incorporating the soil moisture sensor as a result of our climate station shall be mounted to the roof of the constructing. Nonetheless, customers might want to account for the quantity of cable required for his or her setup and the publicity of {the electrical} parts on the sensor.
  • Humidity
    • Whereas it might be supreme to accommodate the electronics in a very waterproof enclosure, this may significantly have an effect on the readings from the sensors. With correct airflow, the humidity sensor will present right readings.
  • UV Mild
    • The enclosure ought to permit UV mild to go by way of; in any other case, the UV sensor won’t be able to make measurements of the daylight. As well as, customers ought to take into account how the sunshine will hit the sensor all through the day.
  • Temperature
    • Much like how a greenhouse traps the Solar’s vitality inside to maintain crops heat, an enclosure can be inclined to the greenhouse impact. On this case, the within of the enclosure would warmth up past the ambient air temperature and supply inaccurate readings.
  • Environmental Elements
    • Climate and electronics often do not combine effectively with one another.
      • Mud and water are a recipe for catastrophe in relation to electronics. It’s possible you’ll need to take into account a conformal coating to guard the board from the weather if you’re not utilizing a sealed enclosure.
    • When mounting your climate station outdoors, take into account components equivalent to excessive wind, lightning, and so forth.
      • The pole within the climate meter equipment is metallic and will act as a lightning rod, the place a lightning strike might arc and comply with the ability cable from the climate station.
      • With excessive winds, your harmless climate station could develop into a weapon of destruction if it will get unfastened.
      • For enclosures that are not fully sealed, the mix of excessive wind and rain might permit water to penetrate the enclosure.
      • Even when your enclosure is totally sealed, chances are you’ll need to have a desiccant bag to forestall condensation from forming. (Because the enclosure is already sealed, the humidity readings won’t be related.)


Relating to measuring climate precisely, some specialised sensors are required. Fortunately, the SparkFun Arduino IoT Climate Station contains virtually every part required to construct your climate monitor station.

  • Customers might want to buy a suitable enclosure, mounting {hardware}, and energy equipment individually. (Most of these things could be discovered at your native ironmongery shop.)

{Hardware} Setup

Climate Meter Package

Customers might want to assemble the climate meter equipment. If you’re unfamiliar with the climate meter equipment, try our meeting information:


The enclosure are housed the electronics and defend them from the weather.

  • Connect the MicroMod ESP32 Processor board to the Climate Provider board.
    • Program the board (see Software program Directions part under)

      Be aware: We advocate that customers program their board and take a look at their sensors and WiFi connection in a managed setting earlier than mounting any outdoors {hardware}. This can facilitate troubleshooting and isolate points associated to the enclosure, mounting {hardware}, mounting location, and/or WiFi connection.

  • Mount provider board to the enclosure
  • Drill gap(s) for wiring

Be aware: If you’re unfamiliar with our MicroMod merchandise, please try the next hookup guides earlier than continuing:

Mounting the Climate Station

  • Mount the climate meter equipment

    Be aware: When mounting the climate meter equipment, orient the wind vane sensor to the suitable cardinal instructions. In any other case, customers ought to recalibrate the sensor’s ADC values within the Arduino sketch.

  • Mount the enclosure
  • Join the ability and RJ45 sensor cables to the climate provider board

Software program Directions

The software program and venture directions could be discovered on the Arduino Undertaking Hub: Climate Station with Arduino Cloud. Customers may also obtain the code from the GitHub repository for the venture.

Be aware: The Arduino Undertaking Hub submit does an ideal job of summarizing the data wanted to arrange your gadget and dashboard. Nonetheless, if you’re nonetheless accustomed to the Arduino Cloud platform and want to see their full directions on creating a tool, configuring a factor, and dashboard, please try their getting began tutorial.

Be aware: Within the Undertaking Hub submit, there’s a desk of variables from the Arduino sketch. The Beginning Plan column signifies which Arduino Cloud plan(s) will permit customers to entry these variables (see the Be aware under).

thing variables

Be aware: Relying in your Arduino Cloud subscription, you may have a restrict on the variety of most variables which can be obtainable to configure. (Test the total record of supported options for every plan.)

Most variety of variables per plan:

  • Free: 5
  • Entry: 10
  • Maker and Maker+: Limitless

For instance, you solely should create _uvIndex_ variable in case you have an Entry or superior plan ( Entry, Maker, or Maker +).

Take pleasure in!!!

After the {hardware} setup and programming was finished, we arrange our Arduino Cloud account and created our dashboard. The brand new climate station was then mounted on the roof of the SparkFun HQ constructing. Here’s a have a look at the information from our new climate station on the Arduino Cloud dashboard:

We additionally created a separate dashboard to show historic knowledge from the final week (earlier 7 days). (Click on to enlarge)

Be aware: At present, you can’t publicly share a dwell view of your dashboard. Nonetheless, the Arduino Cloud platform does permit customers to share their dashboard on to different customers (by way of e mail hyperlink).

Are you prepared to attach your IoT Climate Station to Arduino Cloud?
