SparkFun launches ESP32-based “Arduino IoT Weather Station” with Arduino IoT Cloud integration

SparkFun’s Arduino IoT Weather Station is a complete weather station kit leveraging the company’s MicroMod ecosystem with an ESP32 Processor Board and various sensors and developed in collaboration with Arduino for integration into their IoT Cloud service.

Most people will check the weather on the Internet or watch the weather forecast on TV, but if you live in a remote area with a micro-climate or just want to have fun building your own weather station, the latest SparkFun kit will allow you to monitor temperature, air and soil humidity, wind speed and direction, lightning, and rainfall data at home and monitor the data from anywhere using a web browser.

Arduino IoT Weather Station kit content:

  • MicroMod ESP32 Processor module
  • MicroMod Weather Carrier Board with a BME280 temperature, pressure, and humidity sensor and an AS3935 lightning detector only. The optional VEML6075 UV sensor is NOT included.
  • The Weather Meter Kit with
    • Wind vane
    • Cup anemometer
    • Wind meter mounting bar
    • Tipping bucket rain gauge and mounting arm
    • Two-Part mounting Mast
    • 2x mounting clamps
    • 4x zip ties
  • SparkFun Soil Moisture Sensor with screw terminals (Note: variable resistance soil moisture sensor)
  • A pack of ten “premium” jumper wires

Arduino IoT Weather Station KitSparkFun has been selling the Weather Meter Kit for a little while, but people had to purchase the other parts separately, so the company decided to provide a complete weather station kit with everything needed to get started and easy integration with Arduino IoT Cloud. You’ll find the Arduino library and documentation for the kit on GitHub. It works not only with the MicroMod ESP32 Processor module but also other MicroMod M.2 modules based on Raspberry Pi RP2040, Microchip SAMD51, Nordic Semi nRF52840, etc… The ESP32 module has been selected for the kit because WiFi connectivity makes it easier to integrate with the cloud. Since the Arduino IoT weather station comes as a kit, SparkFun also published an assembly guide.

You’ll find a short introduction and demo video with the Arduino IoT Cloud below. Some of the commenters on YouTube mention that variable resistance soil moisture sensors tend to go bad because of corrosion caused by the DC current, and a capacitive moisture sensor should be more durable. Some wish the kit could be solar-powered, but it should not be too hard to find a USB solar panel kit since it’s what my WiFi and 4G LTE security cameras are using.

SparkFun is selling the Arduino IoT Weather Station for $124.95 plus shipping.

I am not a big fan of all those moving part. I just found yesterday an article with a wind speed and direction sensors without moving parts (“Ultrasonic Anemometer”), that looked really interesting for $75.

If you found them this week you just haven’t been looking for the last 10 years.

General problems with the ultrasonic anemometers are the blind spots since the casing disturbs the windflow and produces a significant error at mostly 4 distinct angles.

If ultrasonic was good they would have been installed at every racing yacht.
