Description

The BME280 is a high-precision, low-power digital sensor combining barometric pressure, temperature, and humidity sensing in a single MEMS package. This module version is encased in a black plastic shell with an internal cotton core, which provides mechanical damping and stability for the sensing element. The integrated signal conditioning and 24-bit ADC deliver calibrated digital output directly via the I2C bus.

Designed for reliable operation in demanding environments, the sensor maintains specified accuracy across its full temperature range. The included 1-meter cable and card holder facilitate straightforward mounting and integration into weather stations, portable monitoring devices, or HVAC control systems.

Key Features

  • All-in-One Environmental Sensing: Measures barometric pressure, ambient temperature, and relative humidity with a single digital sensor.
  • Stable Mechanical Design: Black plastic housing with an integrated cotton core dampens vibration and protects the MEMS die.
  • Digital I2C Interface: Provides calibrated, high-resolution digital data for easy microcontroller integration.
  • Broad Operating Ranges: Functions from -40°C to +85°C and 300 hPa to 1100 hPa pressure.
  • Low Power Consumption: Optimized for battery-powered and always-on monitoring applications.
  • Integrated Cable & Mounting: Includes a 1-meter cable and a plastic card holder for secure installation.
  • Wide Voltage Compatibility: Operates from a single 3.3V or 5V DC power supply.

Applications

  • Portable weather stations and atmospheric data loggers.
  • Indoor air quality (IAQ) monitoring and smart HVAC control systems.
  • Altitude tracking and navigation aids for drones and UAVs.
  • Environmental monitoring in agricultural and industrial settings.
  • Battery-powered IoT sensor nodes for building automation.

Frequently Asked Questions

What is the supply voltage range for this BME280 module?

The module is designed to operate from a single DC power supply ranging from 3.3 volts to 5 volts. Ensure your microcontroller or host system can provide a stable voltage within this range for proper sensor operation and accurate readings.

How do I communicate with this sensor? What is the pinout?

Communication is via the I2C (Inter-Integrated Circuit) serial protocol. The standard 4-pin interface typically includes VCC (3.3V/5V), GND, SCL (clock), and SDA (data) lines. The specific pin assignment is marked on the module's PCB or connector. Refer to the BME280 datasheet for the I2C address and protocol details.

What is the purpose of the cotton core inside the black shell?

The built-in cotton core acts as a mechanical damper and filter. It helps stabilize the sensor by dampening vibrations and protecting the sensitive MEMS element from dust and particulate matter, which can improve long-term measurement stability, especially in dynamic environments.

Can this sensor be used outdoors?

Yes, the BME280 is rated for an operating temperature range of -40°C to +85°C, making it suitable for many outdoor applications. However, the plastic housing is not fully sealed (no specified IP rating). For prolonged outdoor use, consider providing additional weatherproofing or an enclosure to protect the electronics from direct water ingress.
