BME680 Environmental Sensor
BME68X Environmental Sensor for Temperature, Humidity, Pressure, and Gas Monitoring With SPI/I2C Interface
This product is a high-precision environmental sensor featuring the BME68X sensor, capable of monitoring temperature, humidity, atmospheric pressure, and VOC gases. The chip supports a temperature measurement range of -40 to +85°C, a humidity measurement range of 0–100%, and an atmospheric pressure measurement range of 300–1100 hPa.
The module connects to development boards via a PH2.0 6-pin cable, enabling environmental monitoring. It supports SPI/I2C interfaces for flexible communication. Additionally, we provide example programs compatible with Arduino, Raspberry Pi, Raspberry Pi Pico, and ESP32, allowing real-time monitoring of temperature, humidity, atmospheric pressure, and gases.
Product Features
- Onboard BME68X Sensor: Capable of measuring temperature, humidity, atmospheric pressure, and gases.
- Flexible Interface Options: Supports both I2C and SPI communication interfaces, with I2C set as the default.
- Onboard RT9193-33 Linear Regulator: Features low power consumption and fast startup time.
- Integrated Level-Shifting Circuit: Ensures compatibility with both 3.3V and 5V systems.
- Open-Source Example Programs: Provides example codes for Arduino, Raspberry Pi, Raspberry Pi Pico, and ESP32 platforms.
