About this item

The 7Semi LPS28DFW Mini Absolute Digital Barometer is a high-precision pressure sensor designed for applications requiring accurate barometric measurements. It offers dual full-scale pressure ranges: 260–1260 hPa and 260–4060 hPa, with an absolute pressure accuracy of ±0.5 hPa. The sensor operates with a low supply voltage range of 1.7V to 3.6V and consumes minimal current, as low as 1.7 µA in one-shot mode, making it suitable for battery-powered devices. Communication is facilitated via an I²C interface with selectable addresses (0x5C default, 0x5D). Its compact, water-resistant design ensures durability in various environmental conditions. The sensor is ideal for applications such as weather stations, altimeters, and portable devices requiring reliable pressure measurements.
