SenseCAP S2100 - LoRaWAN® Data Logger/DTU, Supports RS485/Analog/GPIO Interfaces, LoRaWAN Converter

RM 0.00


SenseCAP S2100 Data Logger/DTU can connect to MODBUS-RTU RS485/Analog/GPIO sensors and transmit data from sensors to the LoRaWAN network. Benefits from LoRa and IP66 design, this device features stability and reliability and can cover a long transmission range while keeping ultra-low power consumption, ideal for outdoor use. It is specifically optimized for OTA with built-in Bluetooth, which enables quick setup and update. It can be battery-powered or connected to a 12V external power supply. When the 12V power supply is connected, the replaceable built-in battery is set to be used as the backup power supply. What's more, with the help of S2110 converter, S2100 Data Logger/DTU is able to connect to Grove Sensor, it is an ideal solution for developing, fast prototyping, and small deployment for DIY Industrial level LoRaWAN Sensors.


  • Strong Compatibility with different Sensors: supports all MODBUS-RTU RS485/Analog(4~20mA/0~10V) / GPIO(level/pulse) sensors.
  • Compatible with Worldwide LoRaWAN® Networks: Compatible with LoRaWAN® V1.0.3 protocol and can work with LoRaWAN® gateway. (support the universal frequency plan from 863MHz ~928MHz).
  • Long Range & replaceable Battery powered: With LoRaWAN® wireless transmission, S2100 supports 19Ah built-in battery and external 12V DC to supply devices, and ultra-wide-transmission range of 2km in urban scenes and 10km in line of sight scenes.
  • Designed to Use in Harsh Environments: -40℃ ~ 85℃ operating temperature and IP66 rated enclosure, suitable for outdoor use, high UV exposure, heavy rain, dusty conditions, etc. 
  • Remote configuration and management: Seeed provides SenseCAP Mate APP and SenseCAP Portal, allows users to remotely manage data and configure.


S2100 LoRaWAN Data Logger/DTU supports MODBUS-RTU RS485/Analog/GPIO input and transmit the data from sensors to the LoRaWAN network.

It can cover a transmission range of 2km in urban scenes and 10km in line-of-sight scenes while keeping lower power consumption during the transmission process. It supports -40 ~ 85℃ operating temperature and can be deployed in harsh environments. With Bluetooth 5.0 for easy configuration and firmware upgrade, It is also compatible with a wide range of frequencies(863MHz ~928MHz), different gateways, and LoRaWAN network servers.

Power Source Option

Option 1: the data logger/DTU can work in Periodic mode. Powered by a built-in 19Ah Standard D-size Li-SOCl2 battery which is easy to buy online, it can be installed and deployed in an outdoor environment without additional power.

Option 2: the data logger/DTU can work in Constant Power mode with an external 12V DC power supply. We provide a matching Junction Box Kit so that the data logger/DTU can be quickly assembled.

Support Industrial Sensors of Different Interfaces

S2100 LoRaWAN Data Logger/DTU is a single-channel collector, and only supports one of the following protocols at one time:

  • RS485: Support standard RS485 Modbus-RTU protocol
  • Analog: 2 x 0~10V or 2 x 4~20mA.
  • GPIO: 1 x GPIO, collect level or pulse signal


System Architecture

LoRaWAN® gateways can provide LoRaWAN® network coverage which is required when using S210x. S210X can be connected to different LoRaWAN® gateways. Here at Seeed, we provide 2 options for choosing the gateways.

Helium Network: Sensors work in areas covered by Helium Network (Helium Explorer). Seeed offers 2 gateways for Helium network - SenseCAP M1 and SenseCAP M2.

LoRaWAN Network: S21XX is fully compliant with LoRaWAN specifications and can be used with gateways support different LNS like The Things Network, Loriot, Chirpstack, etc. we also provide SenseCAP Outdoor Gateway and the indoor SenseCAP M2 Multiplatform Gateway to help you use S210X seamlessly.

We highly recommend that you use our SenseCAP M2 Multi-Platform LoRaWAN Gateway, which is a standard LoRaWAN® gateway that supports connection to different network servers. With its affordable price of $99, its cost-effectiveness becomes a standout advantage, especially when building your private LoRaWAN network.


Cloud Service

Seeed provides the SenseCAP Portal platform and SenseCAP Mate APP to help users better manage and check data remotely.

SenseCAP Portal is a web service to enable users to manage SenseCAP devices and view data through the web.

  • Bind and manage all devices in one account
  • Includes Dashboard, Device Management, Data Management, and Access Key Management
  • Provides MQTT and HTTP API to users for further development

SenseCAP Mate is a powerful APP for data visualization and remote device management.

  • Save time - provides a scan-and-play experience to enable users to complete the whole configuration in 4 steps
  • Works for people with less or no technical background to get started with sensor data easily
  • Acquire and view data on clean user interfaces
  • Set time intervals: improve the battery efficiency
  • Set threshold values: focus on the data you need to take action for - coming soon
  • Send alarms if data is out of the safe range - coming soon


Apart from working with existing sensor nodes, the S2100 data-logger can also be connected with SenseCAP S2110 Grove Converter to achieve a plug-and-play outdoor LoRaWAN sensor deployment experience with various selections of Grove Sensors. It is an ideal solution for developing, fast prototyping, and small deployment for DIY Industrial level LoRaWAN Sensors. Moreover, you can use your existing Seeed Grove Sensors to build your outdoor LoRaWAN sensors without coding. You should try out this kit.

High-performance Guarantee

We are well aware that the sensors may work under harsh outdoor conditions. To ensure that the performance and durability of the sensors are consistent with their specifications throughout the complete lifecycle, SenseCAP S210X went through 6 reliability tests before releasing and met the requirements to perform perfectly in extreme conditions.

  • High-Low Temperature Test - determine performance under adverse temperature conditions.
  • Conformance Test - whether the collected values of multiple devices are consistent
  • Waterproof Test
  • Freezing Test
  • Long-Range Communication Test - whether the device loses packets under long-distance transmission
  • R&D and Production Test - to test the pass rate of multiple devices under factory conditions
