It communicates via I2C or SPI, making it suitable for indoor air quality monitoring, weather stations, and altitude tracking projects. With ultra-low power consumption, it's ideal for battery-operated or IoT devices.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensor Chip\u003c\/td\u003e\n\u003ctd\u003eBosch BME680\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eI2C (up to 3.4 MHz) or SPI\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V (pin tolerance 1.8–3.6V)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTemperature Range\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C (±1°C accuracy)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHumidity Accuracy\u003c\/td\u003e\n\u003ctd\u003e±3% relative humidity\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePressure Accuracy\u003c\/td\u003e\n\u003ctd\u003e±1 hPa (300 to 1100 hPa range)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/pm2-5-air-quality-monitor-kit\"\u003eIndoor air quality monitor with VOC and temperature display\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003ePersonal weather station with data logging to an SD card\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eAltitude logger for drones, rockets, or hiking GPS trackers\u003c\/li\u003e\n  \u003cli\u003eSmart home environmental sensor for automated ventilation control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis module operates at 3.3V, so it works directly with 3.3V microcontrollers like ESP8266, ESP32, and Raspberry Pi. For 5V boards such as Arduino Uno, use a logic level shifter or ensure the I2C pull-up resistors are connected to the 3.3V rail. It pairs well with common I2C display modules (OLED\/LCD) for standalone readouts.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eFor I2C, connect VCC to 3.3V, GND to ground, SDA to data, and SCL to clock; the breakout often includes pull-up resistors. When using SPI, connect CS to a digital pin, SDI to MOSI, SDO to MISO, and SCK to clock, keeping wiring short to avoid signal integrity issues.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days.

For accurate results, calibrate with a reference sea-level pressure value from a weather station.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan this sensor measure CO2 levels directly?\u003c\/summary\u003e\u003cp\u003eNo, the BME680 measures broad VOCs but not CO2. Some libraries estimate equivalent CO2 (eCO2) based on gas resistance, but it is not a substitute for a dedicated CO2 sensor.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
