RFID, AIDC and IoT New Round Up for Sept. Oct. 2, 2019
The future many predict of perhaps tens of billions of connected things assumes many of the Internet of Things devices will come with sensors that monitor conditions such as temperature, humidity and other attributes has just one problem – how will all those sensors be powered?
The passive RFID tags generally connected to those sensors to identify the IoT device and perhaps store other information can be powered by the very act of reading the tags – the radio waves transmitted by the reader allows the tag to pick up energy from what’s called the backscatter effect.
