IDT's relative humidity sensors offer high accuracy and fast measurement response times, enabling customers to improve overall system performance and feedback control. The humidity sensor ICs feature excellent long-term stability as a result of a robust silicon carbide construction and an innovative design, improving useful lifetime and lowering effective cost.
The HS300x family of relative humidity sensors feature a ±1.5% RH accuracy and six-second response time (rated 20% to 80% RH range in still air and does not require airflow).
