Product description

What is included?

• BME680 Sensor Module
• Pin header with 6 pins

How is the sensor specified?

• The sensor can measure temperature (-40°C to 85°C), relative humidity (0% to 100%) and air pressure (300hPa to 1100hPa).
• In addition, the sensor measures different gas concentrations and provides indoor air quality (IAQ index, 0-500).

What supply voltage does the sensor need?

• The sensor module accepts 2.6 V to 5.5 V on the VCC pin.

How to read the sensor?

• First, the pin header is soldered to the PCB.
• The sensor module is then connected to an Arduino or similar microcontroller board.
• Finally, a program is uploaded to the microcontroller.

How do I connect the sensor module to an Arduino Uno?

• First connect the power supply, i.e. connect GND and GND and then connect the VCC to 5V or 3.3V.
• For I2C communication, connect the SDI pin to the A4 pin of the Arduino and the SCK pin with the A5 pin.
• For SPI communication, connect the SDI to MOSI, SDO to MISO and SCK to SCK. On the Arduino, the MOSI, MISO and SCK pins are on the ICSP connector.
