ແນະນຳ

The WF282 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a low current consumption. The WF282 is both a pressure and a temperature sensor. The pressure sensor element is based on a capacitive sensing principle which guarantees a high precision during temperature changes. The small package makes the WF282 ideal for mobile applications and wearable devices.
