Global Water 4046 Analog to SDI-12 Converter

The 4046 Analog to SDI-12 Converter provides an interface to convert inputs from two analog sensors and one pulse counter to an SDI (serial data interface). It also provides internal measurements of battery voltage and ambient temperature. The Analog to SDI-12 Converter responds to all basic SDI commands and enters a low power sleep state when it is not being polled.

The 4046 Analog to SDI-12 Converter has user programmable slope and offset values for the analog and pulse counter inputs. The converter has a user programmable sensor warm-up time and temperature scale can be changed from °F to °C or vice versa.
