Renesas’ humidity sensors offer high accuracy, lowest power with the fastest measurement response time of comparable devices currently on the market.
The HS300x and HS400X families of relative humidity sensors feature a ±1.5% RH accuracy, both digital and analog outputs covering supply voltages of 1.8V to 5.5V and waterproof IP67 options available. The HS400X offers the lowest power consumption on the market with an average of 1.0µA average (one RH + T measurement per second)
This is especially important for battery-powered applications where lower power consumption equates to longer battery life. In addition to high-accuracy and fast response times, the HS300x and HS400X family features excellent long-term stability of 0.1% RH per year as a result of a robust silicon carbide construction and an innovative design. This improves useful lifetime and lowers effective cost.

About Humidity Sensor ICs (RH Sensors)
A humidity sensor IC (also known as an RH sensor or humidity detector) is a device used to measure relative humidity (RH) within a system and digitally report that information back to the system. Several factors influence the quality of a humidity sensor, including accuracy, response time, resolution, and year-over-year drift. Renesas' humidity sensors feature industry-leading specifications, helping to solve product design challenges and giving customers a competitive advantage.
