What Are The Power Requirements For Ni Wsn Devices?

1.	What Are The Power Requirements For Ni Wsn Devices?
Answer» The measurement NODES can operate on four 1.5 V, primary AA alkaline or LITHIUM cells or an external supply. Some NI WSN nodes support battery back-up, meaning the NODE will automatically switch over to battery power if external power is lost. When nodes are configured as routers, they must remain on to SEND and receive data across the network, and should be powered with an external source. You can use sources other than wall power, such as solar or vibration energy harvesting, to provide external power. The WSN-9791 and NI 9792 gateways requires an external 9 to 30 V power supply.
