Back in the mid 90's when the internet was young, people started experimenting with putting
various devices online. There was a coffee pot, remote control toys, a vending machine, etc. All hooked up to the internet.
My contribution was a Bat House. At the time, I was having trouble attracting bats so I was monitoring
the temperature inside the bat house to see if it was conducive to habatation. And then I thought if
someone could put a coffee pot on the internet, why not a bat house? So this page began. The page
evolved over the years, and in '99 I finally got bats to at least occasionally use my bat house.
But in 2001, I had hardware issues and the live temperature graph went offline and then a few years
later my original bat house bit the dust during a home remodel. And that's how things stood until
COVID-19 gave me some time at home to work on fun little projects.
So it's back! And it's all "new and improved"!

This is a recording of bats using their sonar to find insects. Bats use ultrasonic "pings" which can't be heard by humans so
the sounds have been shifted up into an audible range. For more information on the recording, see
Are there bats yet?
July 19 2022 : I implore you Magic eight-ball, confirm the swirling rumors that Buzbee has bats!"Likely.
Guano is present underneath Buzbee's Bat Box"
June 4 2021 : Tell me magic eight-ball, When will Buzbee get bats in his bat box?"Undetermined.
Just because Buzbee has bats in his backyard doesn't mean they will move into his bat box. It could take years!"
May 19 2021 : Oh magic eight-ball, it's mid-May, does Buzbee have bats in his bat box now? "No.
It's been unseasonably cold in Colorado and there are no signs of bats yet"
April 6 2021 : Oh magic eight-ball, does Buzbee have bats in his bat box? "No.
It's too early for bats in Colorado. Don't expect to see bats until mid to late May."
07/19/2022 : Success! Guano has been seen underneath my bat house. It's likely that it is seeing some use! I'm a bit surprised
as with my previous bat house, it took years before I saw any signs of occupation
06/12/2022 : It's the 2020 bat season! And I have at least one bat up in the eaves again. No sign yet of bathouse use, but it's hard to tell if it's occupied so I'll have to keep an eye on it.
08/29/2021 : There's an area up in the eaves on the north side of our house that has an occasional bat visitor and he's back again this year. I can't see that he has used the bat box yet, but I'll keep an eye out for guano underneath. Here's a picture of a bat leaving the eaves from 21 years ago. Is it possible that it is the same bat after all these years? I don't know.
06/14/2021 : For several years, we've had a bat visiting our front porch for short rests during the night. He's back again this year. Still no signs of him using the bat box.
06/05/2021 : I heard bats on my bat detector last night! And then I saw them circling the back yard. No sign that they are using my bat box yet, but I'll watch for guano underneath.
04/10/2021 : The box is up! Here's a photo of it in place. Now we wait until bat season.
04/03/2021 : Still tweaking the bat box in preparation for season placement
04/01/2021 : First live graph in nearly 20 years. On Aprils Fool's Day nonetheless...
Temperature and Humidity
These measurements represent the temperature inside the bat house,
the outside temperature on the North side of the Buzbee house, and the humidity inside the bat house.
This bat house is quite small, so in general I'd expect the temperature readings to be similar execept
that the bat house is on the South side of my house while the outside reading is on the North. It's
possible that the breath of bats in the house will cause a bump in humidity. I'll monitor for that as
the bat season arrives in Colorado. The vertical black band(s) represent the time between sunset and sunrise.
The chart displays absolute atmospheric pressure within the bat house measured in pascals (Pa).
Since the house is open to the outside, this should generally match up with the Denver area.
This is a chart of the light level inside the bat house measured in lux. As of 4/10, the box is in its final location so I'll keep on this to see how much light gets in. As a reference, 100 lux is considered to be the light level on a very dark day and 10 is twlight.
Sound Pressure Level averaged over all monitored frequencies measured in decibels. The sensor will not detect ultrasonic bat calls that are used
when bats are hunting, but I hope that I can pick up noises when bats arrive and position themselves. A challenge will be to detect these noises within
every other sound that is picked up.
This chart displays the measurement of Volatile Organic Compounds (VOC) from a metal oxide gas sensor. Greater VOC concentrations result in a lower
sensor resistance, while cleaner air gives a higher resistance. I'm hoping that this will let me detect when bats are present.
