| + | ==BMP180== | ||
| - Sensing Principle: The BMP180 sensor uses a piezo-resistive pressure sensor to measure atmospheric pressure. It contains a microelectromechanical system (MEMS) pressure sensor that changes its resistance based on the applied pressure. The temperature is also measured using an integrated temperature sensor. | - Sensing Principle: The BMP180 sensor uses a piezo-resistive pressure sensor to measure atmospheric pressure.

| - Sensing Principle: The DHT11 sensor utilizes a capacitive humidity sensor to measure relative humidity (RH). It consists of two electrodes with a moisture-sensitive layer in between. The capacitance of this layer changes with the surrounding humidity, enabling RH measurement. Additionally, a thermistor (resistor that varies with temperature) is used to measure temperature. | - Sensing Principle: The DHT11 sensor utilizes a capacitive humidity sensor to measure relative humidity (RH).
