Item Description: The light sensor module have strong adaptable to the environment. Having a pair of infrared transmitter and receiver, transmitter launch ... morea certain frequency infrared, when meet obstacle in the detection direction, the infrared receiver is reflected back by the receiver tube, after processing through the comparator circuit, the green indicator light will illuminate while the signal output interface output digital signal(a low-level signal) can be adjusted via potentiometer knob detection distance, the effective distance range 2 ~ 30cm, working voltage is 3.3V-5V. The detection range of the sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used robot obstacle avoidance, obstacle avoidance car assembly line count and black-and-white line tracking and many other occasions. Parameter: 1. When the module detects an obstacle in front of the signal. The circuit board green indicator light levels while continuing output low signal OUT port, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential control to adjust, adjust potentiometer clockwise, the detection distance increases; counterclockwise adjustment potentiometer, detection distance decreases. 2. The sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The minimum detection distance which black and white max; small area of ​​the object distance is small, a large area from the Grand. 3. The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO 4. The comparator using LM393, job stability; 5. Can be 3-5V DC power supply for the module. When the power is turned on, the red power indicator light; 6. With 3mm screw holes for easy mounting, installation; 7. The circuit board size: 3.2CM* 1.4CM 8. Each module in the delivery has threshold comparator voltage adjus

Vintage AMD LM339AN - Low Power Low Offset Voltage Quad Comparator - RARE
SquareTrade © AP6.0 You are buying a RARE LM339AN made by AMD back in the year of 1984. These are new but old items from a private collection. AMD only made these as a second source of National Semiconductor parts. Quad Voltage Comparators in one package. Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 The LM339 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the ... moremagnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground. Even though operated from a single power supply voltage. Application areas include limit comparators. Simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM339 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies. They will directly interface with MOS logic— where the low power drain of the LM339 is a distinct advantage over standard comparators. Plastic 14 pin DIP case with standard leads. These are new.
