  • When I ordered these for my rain gauge project, I missed the word “latched” in the description! Perhaps SparkFun could change the part name to “Latched Hall Effect Sensor”?
    Fortunately, I also ordered 2 reed switches that should work for my project. I’ll have to find something else to do with these, or use the method suggested by JPFlash for resetting the latch by controlling the power with a Digital Output. I thought that was a clever idea.

No public wish lists :(
