- For a 1-wire sensor, put it in the collector of your header, and read the
- voltage (between the wire and ground) with a high-impedance voltmeter,
- prefferably analog, but digital seems to work ok for me. .45 volts is
- stoich, higher is rich, lower is lean. I don't know what voltages
- correspond to theoretical rich peak power and lean peak economy.
