Description
Easy to use temperature and humidity sensor supplied from 3.0 V to 3.6 V. It communicates via the I2C interface. It is used, among other things, for weather stations and systems for controlling indoor conditions.
For proper operation it is sufficient to connect the power supply and the I2C bus lines: SDA data and SCL clock. The board is equipped with 4.7 kΩ pull-up resistors, if other devices are connected to the I2C bus, these resistors can be switched off.

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.
