Regarding the design of micropower isolated power supply for two-wire transmitter, we must know what is the transmitter first. When the output of the sensor is a specified standard signal, it is called a transmitter. As for a sensor, usually composed of sensitive elements and conversion elements, is a floorboard for a component or device that can be measured and converted into a usable output signal according to certain rules. And the common types are power transmitters, current-voltage transmit ...
SummaryA good news that transmitter industry have a futher development is that powercast,a leader in the field of permanent mold aluminium castings,announced its three-watt PowerSpot transmitter is now FCC-approved and ISED-approved for far field(up to 80 feet) over-the-air charging multiple consumer devices.This kind of transmitter doesn't require charging mats or direct line of sight.Product IntroductionCreating a coverage area like Wi-Fi, a Powercast transmitter automatically charges enab ...
Before I share it ,I would like to warn that: Fireworks are illegal in many countries. Before you go lighting off fireworks, check for any local restrictions. Stay safe!There are many articles about remote control lgnition system if you google it. However,I would like to share one but it has some differences between them cause the circuit is combined with my ideas and my friend who is an engineer. Let's see the the complete project details that allow you to ignite firecrackers from a sa ...
Today,I would like to introduce a kine do remote controller built using PT2262,IC PT2272-M4 from PRINCETON and MAX485 from MAXIM.This is a four channel two core twisted pair remote controller. The PT2262 is an enconder( transmitter) whic PT2272-M4 is a decoduer (receiver) and MAX485 works as bridge for twisted pair communication between PT2262 and PT2272-M4.4 Channel 2 core twisted pair remote controller built using PT2262.When any of SW1-SW4 (S1-S4) tact switches is pressed, power is applied to ...
At this year's Consumer Electronics Show in Las Vegas, the big theme was the "Internet of things"—the idea that everything in the human environment, from kitchen appliances to industrial equipment, could be equipped with sensors and processors that can exchange data, helping with maintenance and the coordination of tasks.Realizing that vision, however, requires transmitters that are powerful enough to broadcast to devices dozens of yards away but energy-efficient enough to last for ...
