This driver was developed using the Veris HD2NVSTA1 humidity transmitter. The 'T' variant supports a temperature transmitter as well. Both signals are provided by the device as analog 0-5Vdc or 0-10Vdc outputs. The A1 variant supports a temperature range of -40C-50C, while the A2 variant supports a range of 0C-50C. Humidity ranges for all devices in this device family range from 0% to 100% (non-condensing). Temperature measurement can be disabled by passing -1 as the temperature analog pin to the constructor.
