The compact, long-term stability weather sensor OTT TRH is responsible for the measurement of relative humidity and temperature. In addition it can calculate the values for absolute humidity, dew point and mixing ratio and output these via the SDI-12 interface. A protective cap prevents dust and dirt from entering the sensor system. The included protective housing provides weather and radiation protection.

• Measurement technology: PT1000, capacitive
• Product Highlights: Low power draw, long-term stable, suitable for extreme temperatures, protective housing included
• Interface: SDI-12 V1.3
