by David_Dragino @ instructables.com This is an example to show how to get sensor data from a remote Arduino via Wireless Lora Protocol. The exampels requries below hardwares: 1) Client Side: Arduino + Lora Shield (868Mhz) + DS18B20 (Temperature Sensor). 2) Server Side:...

WISP, the Wireless Identification and Sensing Platform, is a family of sensors that are powered and read by UHF RFID readers. WISP, the Wireless Identification and Sensing Platform, is a family of sensors that are powered and read by UHF RFID readers. WISPs do not require batteries...

A pair of former engineers from Agilent Technologies are working on a wireless oscilloscope that will connect to an iOS device for its user interface: The Aeroscope will be a one-channel device where the electronics are in a "pen" form factor. An SMA connector will let you attach...

Here is a tutorial on how to use 433MHz RF modules to send data from an Arduino to another. The example code transmits a message to the serial port of receiver. The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver....

The LTC4125 is a simple and high performance monolithic full bridge resonant driver capable of delivering over 5W of power wirelessly to a properly tuned receiver. The device controls the current flow in a series connected transmit coil LC network to create a simple, safe and...

Raspberry foundation announced the Raspberry Pi 3 at the same price as the previous board. This new board features 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU with ~10x the performance of Raspberry Pi 1, Integrated 802.11n wireless LAN and Bluetooth 4.1 and full compatibility with the...

Here is a new video of our friends at educ8s.tv: Do you want to add wireless capability to your Arduino Projects? Using the NRF24L01+ module is a very easy and reliable way to do so. This tranceiver module works at the 2.4GHz band and it is extremely easy to use with any Arduino...

Linear Technology Corporation introduces the LTC4123 to further expand its offerings in wireless battery charging. The LTC4123 combines a 30mW wireless receiver with a constant-current/constant-voltage linear charger for NiMH batteries, such as Varta’s power one ACCU plus series. An...
