Finally we have an I2C-interface temperature & humidity sensor in a nice enclosed style. This sensor contains a DS18B20 temperature sensor and a capacitive humidity sensor. A small microcontroller inside does the readings and provides a simple I2C interface for reading the finished & calibrated output data. Especially nice is that this sensor is in a rugged case with mounting bracketwhich makes it way superior to a normal PCB-mounted sensor.
While it is not rated as \'weatherproofhis sensor would do much better for sensing where there might be windrainzombiesetc. than SHT PCB-breakout sensorsand the i2c interface makes it easier to interface with microcomputers that can\'t do the delicate timing of the DHT sensors.
Simply connect the red wire to 5V powerblack to groundyellow wire to your i2c data pinand the white wire to the i2c clock pin. You cannot change the i2c address so only one sensor per i2c bus. Two ~10Kohm pullup resistors are required for useconnect from the SDA and SCL lines to the power wirethe pullup resistors are not included!
