ADT7470 and TMP05 daisy chain temeparure sensing.

I am using the ADT7470 and the TMP05 in a daisy chain configuration and there are five sensors. I get temperature readings that intermittently vary by huge amounts and then return back to the expected temperature.

Please refer the attached documents for more details.

  • Hi Harry

    At the moment we are testing and there is only one transmitter. In the real application also there will be one transmitter per site and will not consist of any repeaters. I am in the process of doing more testing and will keep you updated.

    Thanks
