    SenseCAP Wireless LoRaWAN Barometric Pressure Sensor AU915/AS923

    SenseCAP Wireless Barometric Pressure Sensor measures atmospheric pressure, featuring high-precision, stability, and high EMC robustness. It’s designed with an air pressure sensor, a custom battery, and an industry-grade enclosure, optimized for outdoor use cases that need reliable data collected over years.





    SenseCAP Wireless Barometric Pressure Sensor measures atmospheric pressure in the range of 300~1100 hPa. Featuring high-precision, stability, and high EMC robustness, this sensor is suitable for industrial applications such as weather stations, outdoor farms, tea plantations, greenhouses, and more. 


    This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, a barometric sensor, and a custom battery. It is specifically designed and optimized for use cases powering end devices by batteries for years. To minimize the power consumption, the device wakes up, transmits the collected air pressure data to the gateway, and then goes back to sleep.


    Under the best of circumstances, the battery is expected to last for more than 8 years, depending on the environmental factors and data transmission intervals. Please kindly note that the default interval is once per hour. If you'd like to change the data upload interval, please refer to this document.

    SenseCAP Sensor adopts a modular design, integrating the data-logger with the sensor probe, which can be replaced by other SenseCAP sensor probes. This sensor's data logger is rated IP66, and the sensor probe is rated IP65.
