Si7006/13/20/21/34
Relative Humidity and Temperature Sensor with I2C Interface
Our Si7006/13/20/21/34 family is our latest generation of I2C relative humidity and temperature sensors. All devices combine fully factory-calibrated humidity and temperature sensor elements with an analog-to-digital converter, signal processing, and an I2C host interface. The Si7013/20/21/34 sensors are designed for high-accuracy applications, while Si7006 is targeted toward lower-accuracy applications traditionally using discrete RH/T sensors.
Featuring innovative CMOS design, these devices offer the lowest power consumption in the industry for a relative humidity and temperature sensor. Patented use of industry-standard low-K polymer dielectrics provides excellent accuracy and long-term stability, along with low drift and low hysteresis.
