Building a weather station can be rewarding whether you're an agriculturalist, professional meteorologist, or weather hobbyist. Create your own weather station effortlessly using SparkFun's Arduino IoT Weather Station, seamlessly monitored through Arduino Cloud, an all-in-one IoT platform that brings your creations to life in a snap. SparkFun created this Arduino library specifically for use with our MicroMod Weather Carrier Board (w/o UV Sensor) and MicroMod ESP32 Processor to allow users to easily record wind speed, wind direction, and rainfall data from our weather meter kit with reliable wireless capabilities.

The MicroMod Weather Carrier Board is a peripheral for the MicroMod ecosystem that allows you to create your own weather station with one of a multitude of processors. The carrier board in this kit includes two sensors: the BME280 temperature, pressure, and humidity sensor and the AS3935 Lightning detector.

Along with these onboard sensors, there is a 3-pin latch terminal & cables to add an external soil moisture sensor (also included) and a pair of RJ11 jacks to plug in the wind and rain sensors to connect the included Weather Meter Kit. To top it all off, there is a microSD card slot so you can plug in an SD card to log all that glorious weather data using the MicroMod processor of your choosing!

The rain gauge is a self-emptying bucket-type rain gauge, which activates a momentary button closure for each 0.011" of rain that is collected. The anemometer (wind speed meter) encodes the wind speed by simply closing each rotation switch. The wind vane reports wind direction as a voltage produced by the combination of resistors inside the sensor. The vane’s magnet could close two switches simultaneously, indicating up to 16 different positions, but we have found that eight positions are more realistic.
