BME280 Temperature Humidity Pressure Sensor Module

The BME280 is a high-precision environmental sensor module that measures temperature, humidity, and barometric pressure simultaneously in a single compact package. Based on the BME280 sensor chip, this module delivers exceptional accuracy and stability, making it ideal for weather stations, altitude measurement, indoor air quality monitoring, and IoT environmental sensing applications. The digital output eliminates the need for external analog-to-digital conversion.

Supporting both I2C and SPI communication interfaces, the BME280 module integrates easily with Arduino, Raspberry Pi, ESP32, and other microcontroller platforms. The 3.3V and 5V compatible design ensures broad compatibility without level shifters. Low power consumption enables battery-powered applications with sleep mode drawing less than 1µA. The module includes onboard voltage regulation and pull-up resistors for simplified connections. Perfect for smart home automation, greenhouse monitoring, drone altitude sensing, and portable weather devices. Factory-calibrated sensor ensures accurate measurements without requiring user calibration procedures.
