SenseCAP Wireless LoRaWAN Light Intensity Sensor AU915/AS923

SenseCAP Wireless Light Intensity Sensor measures the intensity of light, which is designed in battery-powered and IP66 enclosure for outdoor use, optimized for use cases that need reliable data collection over years.

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), and API for device & data management. SenseCAP supports different communication protocols, such as LoRa, 2G, 4G, NB-IoT, and more.

SenseCAP Wireless Light Intensity Sensor measures the intensity of light in lux from 0 - 188000 lux, which is designed for outdoor use.

This device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, a 2-in-1 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 temperature and humidity 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 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.
