Hi is there or are you planning support for Texas Instruments CC2650STK.
It looks like a great little package packed with 10 sensors including support for light, digital microphone, magnetic sensor, humidity, pressure, accelerometer, gyroscope, magnetometer, object temperature, and ambient temperature.
well, a thermocouple is just a microvoltage generator. An op-amp can bring the amplification up to the point that a MCP3004 A/D chip can digitize it and send the data. I’ve seen several Xbee Rx/Tx modules, -but they’re expensive. -are you a MESH fan?
With the Cayenne Arduino integration this should be possible. You would send each data point to a virtual pin, and then connect a widget on your Cayenne dashboard to a virtual pin to display the data. Let us know if you can get it going!
