WASN Modular Node


This waterproof node has a built-in 4000mAh LiPo battery, which can optionally be charged via an integrated or external solar module.
The modular design makes it easy to add different sensors using waterproof connectors.
Up to 3 external sensors can be connected directly.
If more sensors are required per node, the sensor connections can be expanded using a distribution cable.
Furthermore, the node can be internally supplied with new interfaces by 2 plug-in modules.
An external antenna can also be connected for areas with poor radio coverage.
Configuration is done with our WASN Configurator software for Microsoft Windows.
