This is the first set of tests, carried out using +5VDC powering an Adafruit BMP280, over 6" and 6 FOOT wires (see explanation inside) -- against a 7 MHz 50 watt ham transmitter with an antenna right outside the window, and tested against? a 4 watt ham 2 meter tansceiver with me holding the cable in one hand, the handitalkie in the other and holding the handitalkie about 1 foot from the cable.? ? The results of this level of testing appear very reassuring.??
Next test will move to testing it running on 3.3V from Dr. Stapleton's Nano, which has resistor pullups to 3.3V.? ?Stay tuned.
