This I2C digital humidity sensor is an accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor – SHT15 Breakout It has a typical accuracy of +-2% with an operating range that’s optimized from 5% to 95% RH. Operation outside this range is still possible – just the accuracy might drop a bit. The temperature output has an accuracy of +-1C from -30~90C. If you’re looking to measure temperature more accurately, we recommend the MCP9808 High Accuracy I2C Temperature Sensor Breakout Board.

Key Features:

A typical accuracy of 2% with an operating range that’s optimized from 5% to 95% RH
The temperature output has an accuracy of 1degree C from -30~90 degree C
A 3.3V regulator and I2C level shifting circuit
3.3V-5V power or logic
Dimensions: 18mm x 16mm x 2mm / 0.7″ x 0.6″ x 0.08″
Weight: 1g
I2C 7-bit address 0x40
