Accuracy, durable, compatibility and easy to use, it has all the attributes of a superior sensor.
This sensor uses SHT1x sensor. SHT1x is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to internally calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows for easy and fast system integration. The tiny size and low power consumption makes SHT1x the ultimate choice for even the most demanding applications.

Improvement List:

Wide voltage range from 3.3V to 5V
Standard assembling structure (Times-of-5mm Center distance between two 3mm mounting holes)
Easily recognitive interfaces of sensors (""A"" for analog and ""D"" for digital)
High quality connector
Immersion gold surface
