# NWIN003 3xdigital temperature sensors

The NWIN003 node has connectors for up to three digital temperature sensors and it can be battery or battery and DC powered. 

It also has internal temperature and humidity sensors identical to NWIN001. The internal sensors are in a enclosure that is closed so they normally shall not be used. 

If an external sensor is installed as the first node sensor, the internal sensors are installed automatically as technical MPs.

* There are three digital temperature sensor connectors (1, 2, 3).&#x20;
* A DC jack (4) is used to supply the node from an external 9-12 V power supply.&#x20;
* There is a holder for 2 AA batteries on the PCB mounted on the lid.&#x20;
* A green LED (6) on the lid board blinks rapidly when the node is unlinked. It also blinks shortly when the data are sent to a linked gateway
* The blue hinge can be removed for easy routing of cables as described in [enclosure-opening](https://help.boomerang3.com/win-gateway-installation-manual/mechanical-installation/enclosure-opening "mention").&#x20;
* The cable slot (5) is used to route the sensor cables as described in [cables-routing](https://help.boomerang3.com/win-gateway-installation-manual/mechanical-installation/cables-routing "mention").
