GY-BME280-3.3 High-precision Atmospheric Pressure Sensor Module

1. Equipped with Bosch BME280 chip, an all-in-one sensor for temperature, humidity and barometric pressure, supports altitude calculation. 2. Operates at 3.3V, dual-interface support for I2C and SPI, compatible with Arduino, STM32, ESP series and other main controllers. 3. Comes with on-board pull-up resistors and filter capacitors for stable circuit; includes pin header for easy soldering and wiring. 4. High measurement accuracy and ultra-low power consumption, sleep current only 0.1uA, ideal for battery-powered IoT devices. 5. I2C address selectable via SDO pin: 0x76 / 0x77, multiple modules can work on one bus. 6. Widely applied in weather stations, environment monitoring, drone altitude measurement, smart home and embedded DIY projects.
