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. 


Please email sensecap[at]seeed[dot]cc to request any technical support for this product.


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


This battery-powered device incorporates a built-in LoRa transmitter based on SX1276 for long-range transmission, a digital light 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 light data to the gateway, and then goes back to sleep.

Under the best of circumstances, the battery is expected to last for 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

To fit in adverse conditions, it is designed with industrial standards and equipped with an IP66 waterproof enclosure, supporting an extended operating temperature range, making it suitable for industrial applications in both indoor and outdoor severe environments.


SenseCAP Sensor Node adopts a modular design, integrating the data logger with the sensor probe, which is replaceable by other SenseCAP sensor probes.


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 an extra huge workload for provisioning.
