I am able to retrieve values from my Decagon ES2 sensor, but only temperature. Conductivity comes back with a value of 0.0. When I hook it up to a Campbell Scientific CR1000 logger, both conductivity and temperature come back with reasonable values. In fact, temperature is the same using the CR1000 as it is the Mayfly. I’m using the pre-programmed code for the Decagon from modular-sensors (see below). Any idea why the second location in the SDI array is returning but not the first?

const char*   ES2SDI12address = "1";      // The SDI-12 Address of the ES2
const int8_t  ES2Power = sensorPowerPin;  // Power pin (-1 if unconnected)
const int8_t  ES2Data  = 7;               // The SDI12 data pin
const uint8_t ES2NumberReadings = 5;

// Create a Decagon ES2 sensor object
DecagonES2 es2(*ES2SDI12address, ES2Power, ES2Data, ES2NumberReadings);
