Manufacturer: SparkFun
Compatibility: Arduino Raspberry Pi


Easy to use temperature and humidity sensor, powered by 2.5 V to 5.0 V. Communicates through an I2C interface. The sensor is used, i.a. for meteorological stations and systems of control of the conditions in the premises.


For proper operation, it is sufficient to connect power and I2C bus lines: of SDA data and of SCL clock. On board mounted are resistors pulling-up the 4.7 kΩ, if other devices are attached to the I2C bus, these resistors can be disabled.


The product is compatible with Arduino

The manufacturer has prepared auser guideanda library along with a sample programfor Arduino users.


Pins are the solder fields, for solderinggoldpin connectors- pitch of 2.54 mm. Therefore, it is possible to connect the system with the breadboardor the main module, usingwires. The set does not containgoldpin connectors, you can purchase them separately.
