Bathroom humidity controller

blockly.parallax.com/blockly/projectlink?id=60669&key=b3c7c1df-7866-4d00-b3fb-f7be386dd98f

Ongoing project. This works in Blocky, but I'm unable to load this in to Solo. I figure they will get there, not worried, and I think it is unable to load due to using user code block to calculate dew point.

When dew point is within threshold, fan turns on. Added with this version, adding time to light timer if dew point is within the threshold. The idea is to ensure the light is not turned off when in the shower. That happened to my spouse.... oops. This uses the temperature/humidity, PIR, and light sensors. Light sensor is for future use.

  • Good work and cool project!
  • Great Project! With some hardware shots, this could go in the Customer Projects thread
  • Thank you. I keep tweeking the code. Before we got a dehumidifier I had to adjust the threshold value summer vs winter. Summer naturally gets dehumidified by the air conditioning. Winter ran closer to the dew point so the fan would run most of the time if using summer setting. I tried using a sudden ramp in humidity to start the fan but I disabled it due to running a lot. I would like to make it learn what is the best setting, but I haven’t figured that out. Other directions are replacing sensor with air quality to add VOC to also turn on fan and see if I can run two bathrooms off one prop.

  • Great progress!
  • This is Sort of funny, and it illustrates a point: engineers think totally differently from everyone else.

    I saw @Capdiamont post and went “hey! Neat! I should build one!”. To which my wife replied “you see that yellow flippie-thingie on the wall? We call that a ‘switch’ and it controls the light and the fan just fine!!!”

    Spoil-sport... :)
  • @JRoark true the normal switches work very well as long as the person works them well. Our family tends to leave the fans off, leave them on for too long or to prevent them from being on too long, turn them off too soon. This solves that. Humidity is a bad thing in the house.
  • @Capdiamont I totally agree about needing some humidity control. We are in Deep South Texas here. 100F at 95% RH is a pretty typical summer day for us. Brutal! Which is why I was very intrigued by your idea. But SWMBO (She Who Must Be Obeyed) ... was not so much. :)

    That kind of thinking is soooo 20th century, jeez!
