An open source rain and humidity sensor couple

Boris Landoni writes about a new open source rain and humidity sensor project:

It detects humidity through two sensors which are to be used alternatively to let us know when there is water on the ground because it’s raining, or when the water level in a flowerpot is too low and it needs watering.

See the full post and more details on his blog, Open Electronics.

    I disagree with the use of the word ‘humidity’. I think many sellers make this mistake.

    Note that SparkFun does not make this mistake:
    SparkFun Soil Moisture Sensor
    https://www.sparkfun.com/products/13322

    That’s a soil moisture sensor. Read some online articles and one would conclude that soil humidity has to do with traditional humidity, that is, water vapor pressure.

    Anyway, they are just conductivity sensors. Moisture detection is merely a crude approximation.

    KH is correct, humidity is moisture in the air. How does it measure that? It doesn’t. Also, with the header pins this probe won’t last more than a few weeks outside, it’ll just corrode.
