Digital Humidity Sensors

MVH4000D High Performance Digital Humidity Sensor

The MVH4000D Series are small digital humidity sensors with high performance and accuracy. The miniaturized smart humidity sensors are fully calibrated and provide standard digital I2C outputs to enable plug-and-play integration. The humidity and temperature resolutions can be independently programmed for maximum flexibility and to minimize power consumption, depending on the application and operating conditions. The micro-Watt levels of power consumption make these humidity sensors the ideal choice for portable and remote applications. The MVH4000D replaces the MVH3200 Series.

The MEMS Vision combined humidity and temperature sensors offer competitive price-to-performance value for various applications and end users. Evaluation kits are available!
