HS300x Humidity Sensor

IDT's HS300x family features a ±1.5% RH accuracy and six-second response time (rated over a 20% to 80% RH range in still air and does not require airflow). In addition to high-accuracy and fast response times, the devices feature excellent long-term stability of 0.1% RH per year as a result of a robust silicon carbide construction and an innovative design which improves useful lifetime and lowers effective cost. IDT's humidity sensors are ideal for a wide range of applications, including measurement of water vapor content in medical oxygen, measurement of humidity in appliances such as refrigerators, as well as monitoring the humidity of air in industrial processes, climate control systems (HVAC), weather stations, and portable personal health devices.
