Temperature and Humidity Sensor

Temperature and Humidity Sensor

This high quality, precision temperature and humidity sensor is housed in a durable solar radiation shield.

Key Features:

  • Includes solar radiation and rain screen, cabling, and mounting arm.
  • O-ring sealed protective housing for internal electronics.
  • Easily replaceable filter for protection from airborne contaminants.

The solar radiation shield is comprised of six UV resistant louvers, providing effective protection from direct or reflected sunlight and rainfall, while ensuring good ambient airflow to the sensor.

The internal electronics are housed in an anodized aluminum tube, sealed at both ends by waterproof O-rings. The humidity sensor is protected from airborne contaminants and insects by a replaceable filter.

The sensor assembly mounts to an aluminum-mounting arm that clamps directly to the weather station mast, providing a lightweight yet rugged support.

A protective cap is used to protect the humidity wafer and is made of a porous high-density polyethylene filter material. Polyethylene is hydrophobic so it does not attract or retain water—it will not cause humidity reading errors when the humidity drops from a high to a low RH value. The filter also provides protection for the humidity wafer from dust and other airborne particles due to its small pore size (35 microns), affording a minimum of 12 months between servicing.

For measuring water or soil temperature, use DigiTemp.
