Seeed 101020193 Grove - BME280 Environmental Sensor

Seeed 101020193 Grove - BME280 Environmental Sensor is a breakout board for Bosch BMP280 which offers high-precision, low-power combined humidity, pressure and temperature sensor.

* High-performance environmental detection: With the help of BME280 module, it can simultaneously detect temperature and humidity, air pressure, to achieve a stronger detection effect. * Robust measurement range: The sensor can operate normally from -40 to 85 degrees Celsius. And atmospheric pressure sensor measurement range is from 300 to 1100 hPa. * Higher measurement accuracy: Only ±1.0°C error when measuring temperature, measure humidity with ±3% accuracy and measure atmospheric pressure with ±1.0 hPa accuracy. * Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications. * Dimensions: 40 (length) × 20 (width) mm * Weight: 3.2 g (for breakout board), 9.3 g for whole package each piece * Battery: Excluded * Input voltage: 3.3V or 5V * I/O voltage: 3.3V or 5V * Operating current: 0.4mA * Atmospheric pressure sensor measurement range: 300 - 1100 hPa (1 hPa= one hundred Pa) with ±1.0 hPa accuracy * Temperature sensor measurement range: -40 - 85 ℃, with ±1.0°C accuracy * Humidity sensor measurements range: 0% - 100% relative humidity , with ±3% accuracy * Measurement modes: Piezo & Temperature, forced or periodic * Chip: BME280 * Interface Bus: SPI, I2C (use either one of them) * I2C: 0x76(default) or 0x77
