Description
Product overview
The SEVEN 3S-RH&AT is a capacitive relative humidity and ambient temperature sensor designed for precise environmental monitoring. The unit is supplied with a mounting facility and protected from direct solar radiation by an ABS radiation shield with four aspirated plates to ensure free airflow.
Working principle
The sensing element is mounted inside a UV-resistant protective shield. The 3S-RH&AT measures relative humidity and ambient temperature via a measuring transmitter with an I²C output and connects through a 7-pin connector to SEVEN irradiance sensors, Sensor Box types, dataloggers or other receiving devices.
Applications
Installation
Verify system operation at ground level before final installation. Position the sensor away from dark, reflective or heat-absorbing surfaces and clear of local heat sources (vents, chimneys). For rooftop installations, mount on the building side facing prevailing winds. Installation is performed in two stages: install the mounting structure, then secure the sensor to the framework.
