Description: 1. Features: The BME680 is a digital sensor module that measures humidity, temperature, air pressure, and approximates altitude in a compact design with an I²C interface. It consists of a ceramic heater for humidity sensing and a thermistor for temperature measurement. 2. Precision Measurements: With a high level of precision, the BME680 provides accurate readings for temperature up to ±1.0°C, relative humidity up to ±3%, and air pressure up to ±1 hPa. These measurements can be useful in various applications from environmental monitoring to industrial process control. 3. Low Power Consumption: The BME680 offers low power consumption during operation, with an active current draw of around 5.2 mA (I²C mode) and standby current under 1 µA, making it well suited for battery-powered projects or remote installations. 4. High Altitude Approximation: The sensor's onboard algorithms can estimate altitude based on the atmospheric pressure measurement, providing an additional useful data poin
