A tiny sensor breakout with BME280 onboard, sensing environmental temperature, humidity and barometric pressure. It supports both I2C and SPI interfaces and is compatible with 3.3V/5V voltage levels. Due to its ultra-small form factor, low power consumption, high precision and stability, the BME280 is well-suited for applications such as environment monitoring, weather forecast, altimeter and IoT projects. The sensor comes with a 20cm PH2.0 6-pin wire. Features Supports I2C (default), configurable slave address Supports SPI, switch to SPI via I/O setting Onboard voltage level translator, compatible with 3.3V/5V operating voltage Comes with online development resources and manual (examples for Raspberry Pi/Arduino/STM32 Specifications Operating voltage: 3.3V/5V Communication interface: I2C/SPI Temperature sensing: -40~85C (resolution 0.01C, accuracy 1C) Humidity sensing: 0~100%RH (resolution 0.008%RH, accuracy 3%RH, response time 1s, delay 2%RH) Barometric pressure sensing: 300~1100 hPa (resolution 0.18Pa, accuracy 1hPa) Power consumption: <0.1mA@1Hz (H,P,T) Dimension: 27mm x 20mm Mounting hole size: 2.0mm Package Contents 1x BME280 Environmental Sensor 1x PH2.0 6-pin wire (20cm) Resources Product Wiki and code examples Pinout PIN I2C SPI VCC 3.3V/5V power supply GND Ground SDA/MOSI I2C data SPI data master output/slave input SCL/SCK I2C clock SPI clock input ADDR/MISO I2C address chip selection,high level (default) address: 0x77; low level address: 0x76 SPI data master input/slave output CS NC SPI chip selection, low active
