    Does MTQ-LAT3-B01 have the ability to accept a 4-20 ma signal from a sensor?

    Hi John
    What type a sensor is this?

    The ST micro GPIO can source upto 25ma output but is not good at sinking current on the inputs.

    Hey Tim,

    We are looking to hook a couple of air pressure sensors to a cell signaling device. After a little more research this afternoon, I guess it would be a 4-20ma (current loop) sensor board that we would need to mount the Dragonfly (or whatever AT&T signalling device we use) on. We thought Libelium’s Waspmote might be a good option (using something other than a Dragonfly) but it only operates up to 120F.
