CJMCU: BME680 4-in-1 Environmental Sensor Module (Gas, Pressure, Humidity, Temperature)

The BME680 Environmental Sensor Module is an all-in-one digital solution for monitoring air quality and atmospheric conditions. It integrates high-linearity and high-accuracy sensors for gas, pressure, humidity, and temperature into a single compact breakout board.

Key Features:

• Indoor Air Quality (IAQ): Built-in MOX gas sensor detects Volatile Organic Compounds (VOCs) from paints, cleaners, and office equipment.
• Precise Barometric Pressure: Ideal for altitude tracking, weather forecasting, and indoor navigation.
• Relative Humidity & Temperature: Fast response times for climate control and automation systems.
• Dual Interface: Supports both I2C and SPI communication protocols for easy microcontroller integration.
• Wide Compatibility: Works seamlessly with 3.3V and 5V logic levels (Arduino, Raspberry Pi, ESP32, and STM32).

Technical Specifications:

• Operation Voltage: 1.7V - 3.6V (Module includes 5V/3.3V voltage regulator)
• Gas Sensor Response Time: < 1s
• Humidity Range: 0% to 100% RH
• Pressure Range: 300 hPa to 1100 hPa
• Temperature Range: -40°C to +85°C
• Interface: I2C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)

Perfect for smart home automation, wearable devices, weather stations, and air quality monitoring projects. Package includes pin headers (soldering required).
