  1. Step 1: Types of Sensors Used for Weather Station

  The following is a list of measurement devices that are used in weather stations:

  1) NodeMCU (ESP12) main board

  2) Thermometer DHT22 thermometer measures temperature. You can measure both the temperature indoors and outdoors, record highs and lows, show trend arrows to indicate temperature rising or falling, and even predict short-term future temperature ranges.

  Hygrometer (DHT22)- A hygrometer measures relative humidity. Relative humidity is the quantity or percentage of water vapor (water in gas form) in the air. Humidity influences environmental factors and calculations like precipitation, fog, dew point and heat index.

  3) Barometer (BME280) – A barometer measures atmospheric pressure. A barometer can help to forecast upcoming weather based on the changes it measures in the atmospheric pressure.

  4) Davis 6410 anemometer measures how fast the wind is blowing, or wind speed. ESP8266 weather stations can display wind speed in MPH, KPH or knots, and record current, peak and average wind speed readings.

  Wind Vane – A wind vane, or weather vane, is an instrument that determines which direction the wind is blowing.

  5) Rain gauge measures rainfall or liquid precipitation
