Ok, for most applications, relative humidity changes slowly. Renesas's HS400X families of relative humidity and temperature sensors deliver results within three seconds. These ultra-low-power devices come in a small, 2.5- × 2.5- × 0.9-mm, DFN-style 8-LGA package. They are designed for mobile and harsh environments. Features include:
- Very low current consumption: 0.3 µA average for 8-bit resolution with a 3.3-V supply
- Ultra-low sleep current: 0.010 µA
- Highly accurate relative-humidity sensing of ±1.5% RH
- Temperature-sensor accuracy of ±0.2°C typical
