What is the GY-BME280 module used for?

The GY-BME280 is commonly used for weather stations, environmental monitoring, IoT devices, smart-home systems, altitude estimation, robotics, and Arduino projects.

What sensor IC is used in the GY-BME280?

The module uses the Bosch Sensortec BME280 environmental sensor IC.

What voltage does the GY-BME280-3.3 module use?

The GY-BME280-3.3 is designed around a 3.3V supply configuration. Always verify the specific breakout board's power and logic requirements before connection.

Does the BME280 support I2C communication?

Yes. The BME280 supports I2C communication, making it easy to connect with Arduino, ESP32, STM32 and other compatible microcontrollers.

Does the BME280 support SPI?

Yes. The BME280 sensor supports both I2C and SPI communication, although the available interface depends on how the particular breakout board is configured.

Can I use the BME280 with Arduino?

Yes. The BME280 can be used with Arduino boards through a compatible I2C or SPI connection and an appropriate software library.

Can the BME280 be used with ESP32?

Yes. The BME280 is commonly used with ESP32 through its I2C or SPI interface, with the sensor's voltage requirements properly observed.

Can the BME280 measure altitude?

The BME280 measures atmospheric pressure rather than altitude directly. Pressure readings can be used to estimate relative altitude when a suitable reference pressure and calibration are available.

Can the BME280 be used for a weather station?

Yes. Temperature, humidity, and atmospheric pressure measurements make the BME280 well suited to compact weather-station and environmental-monitoring projects.

What is the GS1 solder link on the BME280 module?

GS1 is the power-rail solder link used on the described module to connect VDD and VDD_IO together in the default configuration. It should be configured appropriately when separate supply rails are required.

What is the I2C address of the BME280?

The BME280 supports selectable I2C addressing. The exact default and alternate address depend on the state of the sensor's address-selection pin and the breakout-board configuration.

Where can I buy the GY-BME280 BME280 Sensor Module in Bangladesh?

You can buy the GY-BME280-3.3 BME280 Temperature Humidity Pressure Sensor Module from KathalTech, subject to current stock availability.

Product Description

The GY-BME280-3.3 BME280 Atmospheric Pressure Sensor Module is a digital environmental sensor breakout based on the Bosch BME280. It combines three sensing functions in one device, allowing a microcontroller to collect temperature, relative humidity, and atmospheric pressure measurements.

The module is designed for 3.3V operation and provides convenient access to the sensor through an onboard header. It includes I2C pull-up resistors, power-supply decoupling capacitors, and solder links for configuring the I2C address and power arrangement.

The BME280's pressure measurement can also be used to estimate relative altitude when appropriately calibrated, making the module useful for drones, weather stations, navigation experiments, and other projects where environmental and elevation changes need to be monitored.

Power Configuration Note

The module's default configuration connects VDD and VDD_IO through solder link GS1. If separate power rails are used, such as VDD_IO at 1.8V and VDD at 3.3V, the GS1 power link should be removed as appropriate for the board design.

The exact capabilities and pin arrangement can vary between BME280 breakout-board versions. Check the PCB markings before connecting power or configuring the solder links.
