Humidity-Temperature Sensor with Shield
The Elemetron Humidity - Temperature sensor is designed for
accurate and stable measurements in meteorology systems.
The sensor is based on a factory-calibrated Swiss-made element.
It resists dew formation and has excellent long-term stability.
Supports SDI-12.
