BME280 Temperature Humidity & Pressure Sensor Module

The BME280 temperature, humidity and pressure sensor module is a compact I²C environmental sensing board for measuring ambient temperature, relative humidity and barometric pressure. The actual Chip.pk stock uses a BME280 sensor IC and exposes VIN, GND, SCL and SDA connections, making it suitable for weather stations, IoT monitoring, automation and embedded sensor projects.

Description

The BME280 Temperature Humidity & Pressure Sensor Module combines three environmental measurements in a single compact breakout board: temperature, relative humidity and barometric pressure.

The actual Chip.pk stock is a GYBMEP breakout board. Although the PCB carries the generic marking BME/BMP280, the installed metal-lid sensor is visibly marked BME280. This distinction is important because the BME280 measures humidity in addition to temperature and pressure, while the BMP280 does not include humidity sensing.

Bosch specifies the BME280 for an operating range of -40°C to +85°C, 0–100% relative humidity, and 300–1100 hPa barometric pressure. Typical humidity accuracy is ±3% RH, while typical temperature accuracy is approximately ±0.5°C at 25°C under the conditions specified in the datasheet.

This particular breakout exposes a simple 4-pin I²C interface consisting of VIN, GND, SCL and SDA. The bare BME280 IC itself supports both I²C and SPI, but SPI pins are not exposed on this GYBMEP board, so the Chip.pk listing should describe it as an I²C sensor module.

Technical Specifications

Board voltage note: the supplied GYBMEP PCB visibly includes additional regulation/interface circuitry, but an authoritative manufacturer specification for the exact breakout-board VIN range has not been verified. For this reason, the listing should not make an unsupported universal 5V-compatible claim. The Bosch IC voltage specifications above refer to the BME280 sensor itself.

Pinout

The actual Chip.pk stock exposes only these four pins.

Applications / Use Cases

• Indoor and outdoor weather stations
• Environmental monitoring
• IoT sensor nodes
• Smart-home monitoring
• Temperature and humidity logging
• Barometric pressure monitoring
• Altitude-related experiments
• HVAC monitoring projects
• Greenhouse monitoring
• Data logging systems
• Embedded sensor projects
• Robotics environmental sensing
• Educational electronics projects

Compatibility

The BME280 module can be used with development platforms that support I²C communication, including ESP32, Arduino-compatible boards, STM32 and Raspberry Pi, provided the electrical levels and power connection are suitable.

The BME280 IC itself supports two possible I²C addresses depending on hardware configuration. Since the exact fixed address of the current GYBMEP stock has not been electrically verified, the product listing should not hard-code 0x76 or 0x77 as guaranteed. An I²C scanner can be used during setup to confirm the module address.

Libraries for the BME280 are widely available in common embedded development ecosystems. Compatibility with a specific board or library should still be verified against the selected platform and wiring.

FAQs

1. What does the BME280 sensor measure?
The BME280 measures temperature, relative humidity, and barometric pressure using a single digital environmental sensor.

2. Is this module BME280 or BMP280?
The actual Chip.pk stock uses a BME280 sensor IC. Although the breakout PCB is marked BME/BMP280, the installed sensor itself is visibly marked BME280.

3. What is the difference between BME280 and BMP280?
The BME280 measures temperature, humidity, and pressure, while the BMP280 measures temperature and pressure but does not provide humidity measurement.

4. Which communication interface does this BME280 module use?
This GYBMEP breakout exposes a 4-pin I²C interface with VIN, GND, SCL, and SDA connections.

5. What is the pressure measurement range of the BME280?
The BME280 sensor supports approximately 300 to 1100 hPa barometric pressure measurement.

6. What is the humidity measurement range?
The BME280 supports 0 to 100% relative humidity, with typical humidity accuracy around ±3% RH under specified conditions.

7. What temperature range does the BME280 support?
The sensor operating range is approximately -40°C to +85°C.

8. Can I use the BME280 with Arduino?
Yes. The module can be used with Arduino-compatible boards through I²C, provided the supply voltage and logic levels are suitable for the selected board.

9. Can I connect the BME280 to ESP32?
Yes. ESP32 boards support I²C and are commonly used with BME280 environmental sensors for IoT, weather, and monitoring projects.

10. Can I use the BME280 with Raspberry Pi?
Yes. It can communicate with Raspberry Pi through the I²C interface when correctly wired and configured.

11. What is the I²C address of this BME280 module?
The BME280 sensor supports 0x76 or 0x77 depending on hardware configuration. Since the exact fixed address of this stock module has not been electrically verified, use an I²C scanner during setup rather than assuming one address.

12. Is the 4-pin header already soldered?
No. The supplied stock image shows a 4-pin male header included separately and unsoldered.
