Principal of Operation The Smart FINN® boasts an all-in-one sensor – four sensors combined into one. Each sensor is designed to detect a certain range of color – blue, red, green or clear....

6. Properties 6.1. Dimensions 0.486 inch x 0.485 inch x 0.176 inch (not including spring probes) 6.2. Power Source Unlike the original FINN®, the Smart FINN® requires a minimal power voltage source, which may vary from 2.7 volts to 5.5 volts, current is typically 8mA@5V. Power is marked with a + (plus) sign on the PCB and red heat-shrink on the probe. Ground is marked with a – (minus) sign on the PCB and black heat-shrink on the probe. 6.3. Sensor Four sensors combined into one specially designed to detect color: Blue, Red, Green and Clear. 6.4. Controller Because this system is microcontroller...

Rev D - 012516 6.6. Smart FINN Bright Table of Typical Measurements Color Red Amber Yellow Green Blue Infrared Ultraviolet Fluorescent White(red dominant) White(blue dominant) Saturation *These values are for typical environments (25 degrees Celsius). For additional detail, please refer to the technical discussions later in this document. Please note the voltage output is dependent on the color. The highest voltage is output for red and declines as the wavelength declines. 7. Understanding Measurements 7.1. Voltage and Brightness Smart FINN This sensor is designed to accommodate a wide range...

Rev D - 012516 The lower range is for LED’s with lower output intensity, typically less than 2,000mcd. The lower range output is from 0 to Vdd/2, if using Vdd@5Vdc then a 2,000mcd LED gives an output of 2.5V. The output is not linear so a 1,000mcd LED would give 2.0Volts DC out. The upper range is for LED’s with roughly 2,000-20,000mcd outputs. The output of the range starts at Vdd/2. The increase in voltage per mcd is 1/8 the increase on the lower scale. So, for a 3,000mcd LED the first 2,000mcd accounts for 2.5volts in the output and the next 1,000mcd accounts for only 0.75Volts DC. 7.2. Frequency...

Rev D - 012516 *If the sensor is powered up before the LED the first reading cycle may have samples from the unlit time period and thus a second sampling period is needed. If using Test Flow A, then the wait can be reduced to half the worst case. Also wait times can be reduced if the voltage is measured before the frequency. 8. Sources of Error 8.1. Wiring Special care should be paid to the wiring instructions in section 9.1. Improper wiring will result in over-heating and damage to the part. If miss-wiring has occurred, immediate replacement of the damaged part is recommended. 8.2. Outside light...

Rev D - 012516 8.7. Socket Set Height When multiple Smart FINNs are used in the same fixture or duplicate fixtures, then socket set height of each Smart FINN must be the identical. If the socket set heights are varying from location to location, then the voltage(intensity) reading of the Smart FINNs will also vary since some of the Smart FINN will be closer to the LED making the voltage reading stronger, and vice versa. 9. Fixture Considerations Drawings in section 15, 16, and 17 show the TC11SF-R (Right Angle Smart FINN) and the TC11SF-V (Vertical Smart FINN). There are 2 other part numbers...

Rev D - 012516 Once the face appears smooth use cardboard (unpainted) for a final polishing. If you would like to check your finish, view an LED through the conduit and verify the brightness is not diminished. If the end is not polished enough, then some light will reflect off the jagged surface rather than enter the conduit and brightness will be reduced. 9.4. Socket Set Height All of the sockets set height must be identical in a fixture. If the socket set height varies from location to location then the voltage (intensity) reading will also vary for each location. 10.Absolute Maximum Ratings...

13. 3-V DC Electrical Characteristics Characteristics(1) Output high voltage ILoad = –0.6 mA, all I/O pins ILoad = –4.0 mA, all I/O pins Output low voltage ILoad = 0.5 mA, all I/O pins ILoad = 6.0 mA, all I/O pins 14.Other Application Notes 14.1. Low Pass Filter for DC Measurements Some meters will not average for DC voltage measurement. If your meter does not average you can add a simple low pass filter (R=10k, C=0.1uf) to the output for DC measurements. You must wait at least 5msec after the sensor has acquired a reading to get a stable voltage on the capacitor of the low pass filter. Also,...
