Researchers at Northeastern University have developed a groundbreaking new sensor for DARPA. The device is capable of recognizing infrared wavelengths without the need for an external power source.

INFRARED ACTIVATION

A team of researchers at Northeastern University have developed a new sensor powered by the very infrared energy it’s designed to detect. The device, which was commissioned as part of DARPA’s Near Zero Power RF and Sensor Operation (N-ZERO) program, consumes zero standby power until it senses infrared (IR) wavelengths.

Energy from this source heats the sensing elements, prompting mechanical movements that close a circuit and beam out signals confirming that the IR wavelengths have been detected. A grid of nanoscale patches forms a logic circuit, with each patch being constructed with specific dimensions corresponding only to the wavelengths it’s designed to detect.

Consequently, the circuit can be altered to analyze various IR spectra. It’s possible for the sensor to simply detect IR wavelengths in its surroundings, or determine whether the energy that has activated it came from a fire, a person, or some other source.

WAKE ME WHEN I’M NEEDED

A sensor like this is advantageous because it can be placed absolutely anywhere, without the need for a power supply, or access to solar energy. Such versatility sounds like wetware of William Gibson’s Neuromancer, so it’s no surprise it’s fallen into DARPA’s cross-hairs.

1A Constant Current LED Driver Shield Circuit for Arduino Nano

Electronic Kit School. - There are many electronic circuit that design to get 1A constant current in this time. All circuit mentioned aim to result best design and allow us to use this circuit 

There are electronic design circuit to build constant current LED driver for Arduino Nano. One of the 1A constant current LED driver shiled circuit for Arduino Nano is look like in Figure 1 below with the main component used are Arduino Nano that popular today.

In this time, beside we will show you the circuit, here we also will show you component part and global description about this circuit.

Circuit 

  1. Switch
  2. Resistors
  3. Arduino Nano
  4. CAT4101
  5. Capacitors
  6. Variable resistor
  7. LED
Description

Circuit like in Figure 1 above show you about the 1A constant current LED driver shiled circuit for Arduino Nano. From Electronics-lab site describe that 1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET Preset PR1. On board 1W LED is used for testing purpose. External high Wattage LED or multiple LED string can be connected by pulling two wires from the PCB and this shield fit directly on back side of Arduino Nano. Shield also has on board tactile switch connected to Digital D2 pin using pull down resistor if required for any application. On board preset helps to set the maximum constant current. PWM input pin connected to Digital pin D6 of Nano to control the LED intensity. Example code FADE-IN/FADEOUT helps to test the shield.

The board built using CAT4101 IC from ON Semiconductor. The CAT4101 is a constant−current sink driving a string of high−brightness LEDs up to 1 A with very low dropout of 0.5 V at full load. It requires no inductor, provides a low noise operation and minimizes the number of external components. The LED current is set by an external Trimmer preset PR1 connected to the RSET pin. The LED pin is compatible with high voltage up to 12 V, allowing the driving of long strings of LEDs. The device ensures an accurate and regulated current in the LEDs independent of supply and LED forward voltage variation. The PWM/EN input allows the device shutdown and the LED brightness adjustment by using an external pulse width modulation (PWM) signal coming from Arduino Nano D6 pin. The driver features a thermal shutdown protection that becomes active whenever the die temperature exceeds 150°C.
