DS2450Direction

This example from jbetcher demonstrates the use of the DS2450 quad A/D library and the Arduino OneWire library to read wind vane direction.

DS2423WindSpeed

This sketch uses the DS2423 counter chip to read a counter value from a Dallas Semiconductor DS2423.

Datalogger

Writing data to an SD card. Was to be part of the DS2423WindSpeedCalibration program.

DHT11

This sketch uses the DHT11 for temperature and humidity. The accuracy is close to the desktop temperature/humidity instrument.

DHT22

This sketch uses the DHT22 for temperature and humidity. It is a bit more accurate than the 20 year old HIH4030

DS2423WindSpeedCalibration

This sketch was used to get the accumulated count from the DS2423 over ten second windows. The data was continuously displayed over the COM port. While driving around the neighborhood, the count was correlated with the auto speed. As expected, the count/speed line was linear, so a simple map function in the code provides the wind speed.

Humidity Sensor

HIH4030

This is a simple example sketch using the HIH4030.h library.

HIH4030_Humidity_Sensor

This is an example sketch using the SparkFun_HIH4030.h library.

windStation

Windstation is the merger of direction, windspeed and temperature codes.
