Silicon Labs SI7007-A20-IM1

湿度，温度0 ~ 100% 相对湿度PWM

Overview

The SI7007-A20-IM1 family is our second generation PWM 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 two PWM outputs. Si7022/23 sensors are designed for high-accuracy applications, while the Si7007 is targeted toward lower-accuracy applications traditionally using discrete RH/T sensors.

Take advantage of the unique set of features offered by the Si70xx family. With full factory-calibration, Si70xx devices require no additional RH/temperature calibration during PCB assembly. For protection against dust, dirt and chemical contaminants during PCB reflow and during device operation, all Si70xx sensors can be fitted with an optional factory-installed cover. PWM outputs of the entire product portfolio can be easily filtered to produce an analog voltage. Patented use of industry-standard low-K polymer dielectrics provides excellent accuracy and long-term stability, along with low drift and low hysteresis.
