  • humidity sensors and mcstemp

    Hello Michael,

    I want to use a humidity sensor on my 1-wire bus.
    Do you have a sensor to use? (a schematic to share)
    Can I use Interface,trigger and action on mcstemp (V6.2.25)for this sensor?
    regards Piet

    The circuit is simple with a humidity sensor interfaced with an A/D devices. This is normally done with DS2438. Hobby-boards.com is a good source, but be careful the interface does not use one of their proprietary interface devices. They are doing more an more with these. Midon Design also produces a device. You can see it for sale and a schematic at http://midondesign.com/Sensors/sensors.html. mcsTemperature will populate a DeviceValue with the humidity level and this can then be used as an event trigger.
