BME280 3.3V GY-BME280 is a compact digital environmental sensor capable of measuring temperature, relative humidity, and barometric pressure in a single module. It communicates via I2C or SPI interface, making it suitable for Arduino, ESP32, Raspberry Pi, weather stations, and smart home monitoring projects. The module offers stable readings, low power consumption, and fast response time for accurate environmental data collection.
The BME280 3.3V GY-BME280 Sensor Module is a precision environmental sensing solution designed to measure temperature, relative humidity, and atmospheric pressure in a single compact breakout board. Built around Bosch sensing technology, this digital sensor provides stable and repeatable measurements suitable for embedded electronics, IoT development, weather monitoring, and automation systems.
The module communicates through both I2C and SPI interfaces, making it compatible with popular microcontrollers such as Arduino, ESP8266, ESP32, and Raspberry Pi. Due to its small footprint and low power consumption, it is ideal for portable devices and battery-powered monitoring systems. Many developers and students obtain this module for learning and project development through Bigyan Project where environmental sensing projects are commonly implemented.
Unlike basic pressure sensors, the BME280 integrates three sensing elements in one chip. This allows accurate indoor climate monitoring, altitude estimation, and smart automation based on environmental conditions. The onboard mounting hole also allows secure mechanical installation in enclosures or weather station housings.
