The SHT30-D sensor has an excellent ±2% relative humidity and ±0.5°C accuracy for most uses. Unlike earlier SHT sensors, this sensor has a true I2C interface.
The enclosed box is a Sensiron SHT-30 digital sensor but with the 4 data/power wires brought out to bare wires. Any SHT-3x code for a microcontroller will work.
The 1 meter long cable has four wires: Red = VCC (2.15-5VDC), Black = Ground, Yellow = I2C Clock, White = I2C Data.
Simply connect the red and black wires to your microcontroller or microcomputer power + ground. Connect the yellow wire to SCL, white wire to SDA of your controller's I2C port. There are built in 10K resistors so you don't need external I2C pull-ups.
Compared to the DHT22/AM2302, this sensor is more precise, more accurate, and works in a bigger range of temperature/humidity.
