Humidity Sensors Moisten Established Portfolio

Integrated Device Technology adds a family of relative humidity (RH) sensor ICs to its portfolio of advanced sensor products. According to the company. its humidity sensors offer high accuracy with the fastest measurement response time of comparable devices currently on the market.

 

The HS300x family of relative humidity sensors feature 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). Since humidity sensors consume the most power when they are taking a measurement, the fast response time to a stable measurement reduces the amount of sampling needed. This is especially important for battery-powered applications, where lower power consumption equates to longer battery life.

SENSORS EXPO & CONFERENCE

Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

In addition to high-accuracy and fast response times, the HS300x family features excellent long-term stability of 0.1% RH per year because of a robust silicon carbide construction and an innovative design. This improves useful lifetime and lowers its 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.

 

The HS300x family consists of four devices – the HS3001, HS3002, HS3003, and HS3004 offering RH measurement accuracy of ±1.5%, ±1.8%, ±2.8% and ±3.8%, respectively. All devices feature an extremely low 1uA quiescent current for additional power savings, and an extra wide 5% to 95% sensing range for more precise control at the humidity extremes. The devices are offered in a compact 3.0 × 2.4 × 0.8 mm LGA package. The HS300x devices and evaluation boards are available now.
