Description
Easy to use temperature and humidity sensor powered from 2.4 V to 5.5 V. It communicates through a 2-wire interface (similar standard to the popular I2C). High resolution is provided by a built-in 14-bit A/C converter. At 25 °C, the accuracy is 0.3 °C. The sensor is used, among other things, for weather stations and indoor control systems.
For proper operation it is enough to connect the power supply and DATA and SCK data lines. The board is equipped with 10 kΩ pull-up resistors.

Arduino compatible product The manufacturer has prepared auser guide andlibrary with asample program forArduino users. |
The outputs are soldering fields, allowing to soldergoldpin connectors -2.54 mmraster. Thanks to them it is possible to connect the circuit withcontactboardormain module by wires. The set does not includegoldpin connectors,they can be purchased separately.
