ASSEMBLY assembly	The first step with the BME280 TSL2591 Advanced Weather Station is to solder the 6 pin header that comes along with the board. The easiest way to solder the board is to insert the header into a breadboard (long pins down) and solder the short pins to the board.
CONNECTING_VIA_I2C connecting via i2c	Connecting the BME280 and the TSL2591 on the I2C bus is very easy. The first step is to connect the board to the power supply. VCC Pin. Connect the VCC pin from the board to either 5V or 3.3V output from your Arduino. GND Pin. Connect the GND pin from the board to the GND from the Arduino. Great! Now we need to connect both sensors to the I2C bus. The I2C communication uses basically two wires. The clock signal is generated by the Arduino and transferred to the sensor through the SCL line. The Arduino can send commands to both sensors using the SDA line. Just as well, all data from the sensors goes back to the Arduino through the SDA line. Because of that, the SDA line is bidirectional. SDI Pin. Connect the SDA pin from the board to the SDA line on the Arduino. This corresponds to the pin A4 on the Arduino Uno. SCK Pin. Connect the SCL pin from the board to the SCL line on your Arduino. This corresponds to the pin A5 on the Arduino Uno. INT Pin. This is the Interrupt pin from the TSL2591 sensor. You can expand on the BlueDot library to program this pin. Otherwise just leave it unconnected. 3V3 Pin. This is the output from the voltage regulator. You can pull up to 100 mA from this output. Otherwise just leave it unconnected.
DESCRIPTION description	The one thing that the BME280 sensor cannot do, is measure light! Well, we can fix that. The BlueDot BME280 TSL2591 Advanced Weather Station combines two awesome sensors in one single board! While the BME280 measures temperature, humidity, pressure and altitude , the TSL2591 measures illuminance with great sensitivity. Here are 5 features that make the BlueDot BME280 TSL2591 Advanced Weather Station so awesome: Light, Temperature, Humidity, Pressure and Altitude Measurements. You can measure illuminance, temperature, relative humidity and air pressure with high precision. Besides, the pressure measurements allows you to calculate your altitude with a precision of ± 1.0 meters. 3.3V and 5V Power Supply. The on-board voltage regulator accepts anything from 2.6V to 5.5V to supply the BME280 and the TSL2591 sensors. I2C Communication. Using the I2C communication protocol you need no more than two wires to transfer data from and to your board. Data Transfer with both 5V and 3.3V devices. While devices like the Arduino Uno interpret a 5V signal as a logic HIGH, the BME280 and the TSL2591 use 3.3V as a logic HIGH. The on-board logic level converter translates the 5V signals into 3.3V signals and vice-versa. BlueDot BME280 TSL2591 Library for Arduino. Yes! You don't need to struggle with any datasheet! With the BlueDot BME280 TSL2591 Library you can start measuring right away. Just download the library from the Arduino IDE, from Github or directly from our Website.
