Master the Raspberry Pi Pico W with our comprehensive guide. Learn how to set up Thonny IDE, install MicroPython, and start your first IoT project today.
BME280 is an integrated sensor that combines measurements of temperature, humidity, and pressure.
It's often used in IoT and wearable devices for weather monitoring. The BME280 is based on a MEMS sensor, which allows for compact and low-power measurements. The device communicates with other systems using I2C or SPI interfaces.
Input voltage: 1.8 - 5V DC
Interface: I2C (up to 3.4 MHz), SPI (up to 10 MHz)

SCL (Serial Clock Line) and SDA (Serial Data Line) are two of the most important signals used in the Inter-Integrated Circuit (I2C) communication protocol.
I2C is a popular communication protocol used for short-distance communication between microcontrollers, sensors, and other peripherals in embedded systems.
