Si7006/7 USB Dongle Humidity Sensor Evaluation Kit The Si7006/7 humidity and temperature sensor evaluation kit is designed for lower-accuracy RH and temperature measurement applications where discrete RH and temperature measurement circuits have traditionally been used. The Si7006 device provides an I²C interface, while the Si7007 supports two PWM outputs. The accompanying graphical user interface software allows quick and easy access to the features and functions of the Si7006 and Si7007 humidity and temperature sensors, while enabling the evaluation of the sensor’s performance.
