Start with the signal you need to observe
Each branch maps a field requirement to the models designed for it.
Industrial signals
Capture analog loops or dry-contact states without adding a separate wired gateway at the measurement point.
KS31 · KS32 02Environmental sensing
Monitor ambient temperature and humidity or a remote DS18B20 temperature probe.
KS52 · KS53 03Leak safety
Detect water at a point or along a sensing rope and report the event immediately.
KS51 04Room sensing
Combine indoor environment, air quality, occupancy, light, particulate matter, and switch inputs in an 86-box device.
KS61Choose the sensor that matches the field interface
All six models are current products with model-specific power, enclosure, acquisition, and uplink behavior.

-
SENSOR
Acquire
Measure signals, environmental values, leaks, occupancy, or switch events at the field edge.
-
GATEWAY
Forward
A LoRaWAN gateway receives radio uplinks and forwards them over IP backhaul.
-
NETWORK
Operate
ThinkLink handles LoRaWAN network operation, device state, and decoded telemetry.
-
APPLICATION
Use
Applications visualize data, trigger automation, and deliver integrations or alerts.
