02 / CONNECTION

## Match the interface. Then connect the equipment.

Match physical interfaces and application protocols separately.

01 

### Environmental probe

Temperature and humidity sensing elements monitor the environment, with readings on the local LCD.

02 

### Water-leak probe

Leak probes are included only in the corresponding configurations. Choose spot or rope probes for the installation.

For terminal positions, wire assignments and installation, follow the [official wiring instructions](https://www.think-link.net/docs/zh/Device/LoRaWANSensor/ks52)  .

03 / CONFIGURATION

## Choose a configuration that fits your site.

01 Temperature/humidity and spot or rope leak-probe combinations depend on the model.

02 Accuracy values are manual ratings. Confirm delivery specifications for specific measurement ranges or conditions.
