PRODUCT DETAILS
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.
About SenseCAP
Among the first launch of Seeed industrial IoT (IIoT) product series, SenseCAP is focusing on wireless environmental sensing applications: smart agriculture, precision farming, and smart city, to name a few. It consists of hardware products (sensors, data-loggers & gateways, etc.), software services (SenseCAP portal, mobile App, open dashboard), an API for device & data management.
Note
SenseCAP Sensor is fully compliant with LoRaWAN specifications and can be used with standard LoRaWAN gateways. Please choose the corresponding gateway according to the sensor frequency. Seeed also provides SenseCAP LoRaWAN Gateway for you to use with SenseCAP Sensors seamlessly without extra huge workload for provisioning.Note
