The GY-BME280-5V is an all-in-one environmental sensor developed by Bosch. It is the successor to the BMP180 and BMP280, adding a humidity sensor to the mix. This module is famous for its ultra-low power consumption and high stability. Because this specific “GY” version includes a 3.3V regulator and level shifters, it is 100% plug-and-play with 5V Arduino Uno/Mega boards as well as 3.3V ESP32/Raspberry Pi systems
Key Features
3-in-1 Sensing: Real-time monitoring of Ambient Temperature, Relative Humidity, and Barometric Pressure.
Altimeter Function: By measuring air pressure changes, you can calculate altitude with ±1 meter accuracy.
Dual Interface: Supports both I2C (standard) and SPI (high speed) communication protocols.
Onboard Voltage Regulator: Safe to power from 3V to 5V DC.
Factory Calibrated: Every sensor comes pre-calibrated from Bosch for out-of-the-box accuracy.
