</div>Hi Julian,<br>
<br>
of course one can "manually enter the reading" but I think you don't<br>
want to spend your day periodically watching the LCD and then entering<br>
values manually...<br>
<br>
However, it's the same as with temperature, pressure, humidity and so<br>
on. As long as it is properly formatted according to the APRS Protocol<br>
Specification, every other APRS device will be able to parse it.<br>
<br>
With some understanding of electronics you can probably get the reading<br>
from the circuit and transfer it over a serial interface. So it's about<br>
modifying the hardware.<br>
