The Bosch BMP180 Barometric Pressure Sensor is a compact precision module for measuring atmospheric pressure, temperature, and altitude. It features a pressure range of 300–1100 hPa, low noise up to 0.02 hPa, and operates at 1.8–3.6 V with minimal power consumption. The sensor communicates via a high-speed I2C interface and is fully calibrated for accurate readings. With dimensions of 21 × 18 mm and a weight of 1.18 g, it is suitable for embedded systems, weather monitoring, altimeters, and IoT applications requiring precise pressure and altitude data.
