Temperature and humidity controller with RS232 output

TECHNICAL DATA

Transmitter temperature and humidity with two relay outputs.

Use Case exterior and interior.

Relative humidity, temperature probe on cable.

The measured values ​​are also converted to other interpretations of humidity: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Three inputs with two states.
