Infrared Proximity Detection with PSoC
Introduction
Infrared sensors are light sensors, which are active and function in the infrared part of the frequency spectrum. They primarily consist of an infrared emitter and an infrared receiver. They are found in many object detection applications such as automatic door openers and burglar alarms, surface feature detection, rotation shaft encoding,and barcode decoding. Some recently used applications in mobile devices include auto call-answering, auto speakerphone activation, and detection of flip-in-clamshell phones. This application note is bundled with the firmware and hardware for demonstrating interface and analog signal processing of infrared proximity sensors using PSoC. It alsoexplains infrared light sensing and the advantages of using PSoC in this solution.
Infrared Proximity Sensor
The infrared sensor is made up of the emitter (infrared LED) and detector (photodiode). The emitter emits IR light pulse and the receiver detects the corresponding light pulse. The sensor is classified into transmissive and reflective sensors. As shown in Figure 1, in a transmissive sensor, the emitter and the detector face each other. Objects are detected if they interrupt the beam of light between the emitter and the detector.
For a reflective sensor, the emitter and the detector are next to each other, and are separated by a barrier. Objects are detected when light is reflected off them and back into the detector. The reflective sensor can be used in proximity detection. Some vendors provide a built-in sensor that includes the receiver and transmitter in a small package. In this application note, Avago HDSL-9100 is used in the demonstration circuit. to drive the LED at a higher current (possibly higher than 100 mA peak). The infrared intensity of the emitter influences the detection range. Considering the critical requirement of the PCB size in mobile phone application, the demonstration circuit uses two GPIO pins to drive the LED in parallel and provide current to the emitter. On the IR receiver side, the desired output voltage depends on the detection distance and the value of the load resistor (RLOAD). This output voltage signal can be connected to the next stage, such as an analog amplifier, comparator, or Schmitt-Trigger, to control various functions.
The selection of the load resistor, RLOAD, plays a significant role in circuit operation. If the RLOAD is too large, the RC time constant increases, thereby increasing the response time. However, if the RLOAD is too small, it contributes more
thermal noise to the circuit than higher ones. Therefore, it is important to note the current-to-voltage transfer characteristics for this part of the circuit. According to the applications, the RLOAD can be selected in a range of 50 Kohm to several mega ohms. In this demonstration circuit, we use a 1 Mohm resistor for evaluation.

Bimmian SOLAAARRL Solaris Invisibulbs Load Equalizing Resistor Set Includes extralong wires and all necessary wiretaps for High Output LED Bulbs $37.18 This is the last set of bulbs you will ever need to buy. When going for the Clear Look with a clear lens kit Solaris InvisiBulbsUltrabright Edition are a must. Our New Ultrabright edition is by far the brightest conceaLed bulb on the market today. It is 2 times brighter than our original Solaris InvisiBulbs and are 3 times brighter than the competition. Solaris Electrum InvisiBulbs light up amber (like factory bulbs) while turning Silver and blending in with the lens when off to remove the unpleasant orange reflection in the lens when off. (Solaris bulbs that illuminate a xenon white color are also available as Niveus bulbs). The result is perfectly colorless clear lenses. Our bulbs are made to last hundreds of hours without discoloring or burring out. We guarantee every bulb is delivered to you in perfect working order and will stay that way as long as you own your car. Solaris Electrum InvisiBulbs illuminate in amber. Solaris Niveus InvisiBulbs illuminate in a xenon/hyperwhite color. Both colors of bulbs are hidden when off. New Solaris Jlevisw High Output 32 Led V2 Blubs. Jlevisw and Bimmian Exclusive. After experiencing great success with our Version 1 24Led turn signal kits Jlevisw is proud to present our 32Led high output Led Bulbs. Perfect for your front or rear turn signals backup bulbs and more. Standard Setup Includes:. (2) Led Bulbs of your select fitment and color (Each 32 Led Matrix Design except 7440 which is 30Led). Lifetime warranty. Unlimited access to installation guides and technical support. Benefits of Led Turn Signals:. Instant on instant off blinking. No more slow fade blinking like halogen bulbs. Improved output Leds and more of them to help fill the entire housing with bright colorful light. Improved 6000K colorUnmatched by any hyperwhite halogen bulb (For Xenon Kits).

NYC Resistor $58.94 High Quality Content by WIKIPEDIA articles In February 2008 NYC Resistor took up residence at 397 Bridge Street in Brooklyn NYs MetroTech area. The 800+ sqft warehouse conversion houses, a small kitchen, several shop tables, an epilog laser cutter, and a small machine shop. Numerous electronics projects and personal tools litter shelves of members at the space. A drink mixing robot also has become a permanent fixture at the location. In March 2009 NYC Resistor acquired the neighboring warehouse space on the fifth floor of 397 bridge street and converted it to a machine shop. In March 2010, NYC Resistor will be moving to a new, larger space on 3rd Avenue in Boerum Hill. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

PullUp Resistor $105.14 High Quality Content by WIKIPEDIA articles Pullup resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels if external devices are disconnected or highimpedance. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages. A pullup resistor weakly pulls the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive. When all other connections on the line are inactive, they are highimpedance and act like they are disconnected. Since the other components act as though they are disconnected, the circuit acts as though it is disconnected, and the pullup resistor brings the wire up to the high logic level. When another component on the line goes active, it will override the high logic level set by the pullup resistor. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.
