Seeed Studio SenseCAP S2100 is a LoRaWAN data logger/DTU built for RS485, analog, and GPIO sensor integration in outdoor industrial IoT deployments. Based on the official Seeed description, the SenseCAP S2100 transmits sensor data to LoRaWAN networks, supports Bluetooth OTA configuration, and is designed for long-range, low-power monitoring in harsh environments. Seeed Studio SenseCAP S2100 supports MODBUS-RTU RS485, 0-10V / 4-20mA analog input, and GPIO level/pulse collection. With IP66 protection, -40C to 85C operation, a replaceable 19Ah battery, and optional 12V external power, it is a practical Seeed solution for smart agriculture, industrial monitoring, and rapid deployment of custom outdoor LoRaWAN sensors. Features Strong sensor compatibility: supports MODBUS-RTU RS485, analog 4-20mA and 0-10V, and GPIO level or pulse sensors. LoRaWAN compatibility: works with LoRaWAN V1.0.3 networks and supports the universal frequency plan from 863MHz to 928MHz. Long range and flexible power: supports a 19Ah built-in battery or 12V DC external power, with the battery used as backup when external power is connected. Designed for harsh environments: IP66 enclosure and operation from -40C to 85C. Remote management: supports SenseCAP Mate APP, OTA configuration, and SenseCAP Portal device management.

Industrial IoT monitoring with RS485 and analog field sensors. Rapid prototyping and small deployment of custom outdoor LoRaWAN sensors. SenseCAP S2110 Grove Converter based outdoor Grove sensor deployment. Other Content Seeed Studio SenseCAP S2100 is a single-channel collector and officially supports one protocol mode at a time: RS485, analog, or GPIO. That makes it especially useful when you need a flexible LoRaWAN converter for one field sensor type without redesigning the whole sensing node.
