WiseNet

WiseNetwork

THE Arduino projects have started with small steps getting sensor readings, automation, and so on. Now these projects are going far beyond that. WiseNet is the implementation of Ethernet to Arduino. Our main objective is to wireless transmit readings of any sensor to a computer or broadcast it to the Ethernet so that the user can be aware of these sensor readings while on the go. The applications are endlessly because it has different approaches such as controlling the temperature of a room or what about getting notified if somebody’s home. All that and more can be done using these implementation.

The nRF24L01

nRF24L01

The nRF24L01 is a 2.4GHz transceiver that can be utilized for ultra low powered wireless applications. It’s configuration and operation is through (Serial Peripheral Interface) SPI bus. By saying this, the nRF24L01 operates in full duplex mode having only one master and one or more (up to 6) slaves.

This chip has an embedded baseband protocol engine also named as Enhanced Shockburst™ based on packet communication supporting manual operation to advanced autonomous protocol operations.

Radio front end uses GFSK modulation allowing user to configure different parameters like frequency channel, output power and air data rate. Air data rate supported by the nRF24L01 can be configured to 2Mbps. High air data rate combined with two power saving modes makes the nRF24L01 very suitable for ultra low power designs.

The nRF24L01 has internal voltage regulators that ensure a high Power Supply Rejection Ratio (PSRR) and a wide power supply range.
