BMP180 Pressure & Temperature Sensor with Arduino

The BMP180 barometric sensor (model GY-68) is the one in the following figure (front and back view). It is a very small module with 1mm x 1.1mm (0.039in x 0.043in). BMP180 Pressure & Temperature Sensor with Arduino WHAT IS BAROMETRIC PRESSURE? Barometric pressure (also known as atmospheric pressure), is the pressure caused by the weight of air pressing down on the Earth. Imagine a column of air rising from the Earth’s surface to the top of the atmosphere. The air in the atmosphere has mass, so gravity causes the weight of that column to exert pressure on the surface. HOW THE BMP180 WORKS The BMP180 is a piezoresistive sensor that detects pressure. Piezoresistive sensors are made up of a semiconducting material (usually silicon) that changes resistance when a mechanical force like atmospheric pressure is applied. The BMP180 measures both pressure and temperature, because temperature changes the density of gasses like air. At higher temperatures, air is not as dense and heavy, so it applies less pressure on the sensor. At lower temperatures, air is more dense and weighs more, so it exerts more pressure on the sensor. The sensor uses real-time temperature measurements to compensate the pressure readings for changes in air density.
