RakWireless Barometric Pressure Sensor STMicroelectronics LPS22HB RAK1902

The RakWireless Barometric Pressure Sensor STMicroelectronics LPS22HB RAK1902  is a compact and low-power barometric pressure sensor designed by RAKWireless for the WisBlock system, featuring the STMicroelectronics LPS22HB sensor. It offers a pressure range of 260–1260 hPa with ±0.1 hPa accuracy and temperature sensing from -40 °C to +85 °C with ±1.5 °C accuracy, making it ideal for weather monitoring, altitude estimation, and environmental sensing. The module connects to the WisBlock Base Board via I2C and supports multiple mounting slots (A–F), providing flexibility for integration. It operates with ultra-low power consumption—as low as 1 µA in shutdown mode—perfect for long-term, battery-powered deployments. When paired with the RAK4631 WisBlock Core, the RAK1902 supports data transmission via LoRaWAN®, LoRa®, and BLE, making it suitable for IoT applications. Its modular design allows easy combination with other WisBlock sensors, enabling the creation of a complete weather station or environmental monitoring system.
