SenseCAP S2102 - LoRaWAN Wireless Light Intensity Sensor

The SenseCAP S2102 is a LoRaWAN® sensor designed for precise measurement of light intensity in outdoor and industrial environments. It measures from 0 to 160000 lux with ±5% accuracy and a 1 lux resolution, making it suitable for a wide range of monitoring applications. The device includes built-in Bluetooth for quick setup and OTA (Over-the-Air) updates via the SenseCAP Mate app, streamlining deployment without any coding. Housed in an IP66-rated enclosure and supporting an operating temperature from -40°C to +85°C, the S2102 is engineered for harsh conditions including direct sunlight, rain, dust, and humidity. It transmits over LoRaWAN® networks with a range of up to 2km in urban areas and 10km in line-of-sight environments. Its power-efficient design runs on a replaceable 19Ah Li-SOCl2 battery (ER34615), delivering up to 10 years of operation. The S2102 supports LoRaWAN® frequency plans between 863MHz and 928MHz and is compatible with a variety of LoRaWAN® gateways, including The Things Network, Chirpstack, and Seeed’s own SenseCAP M2 Gateway. The unit has been validated through multiple reliability tests, including extreme temperature cycling, waterproofing, freezing, and long-range transmission trials, ensuring consistent performance across its operational lifespan.

LoRaWAN Frequency S210x Devices are manufactured to support the universal frequency plan from 863MHz ~928MHz in one SKU. That is to say, every single device can support the frequency plans below - the sensor can be switched to other frequency plans at any time:

Frequency Plan Common Name Sub-band

EU863-870 EU868 –

US902-928 US915 Sub-band from 1 to 8

AU915-928 AU915 Sub-band from 1 to 8

AS923 AS923 AS9231, AS9232, AS9233, AS9234

IN865-867 IN865 –

KR920-923 KR920 –

RU864-867 RU864 –

The frequency plan setting is none by default, and it will not transmit RF signal until it has been set by the app via Bluetooth at the first power-up. And it can be changed to other frequency plans at any time. Package Contents
