سنسور اثر هال مغناطيس Hall Module سنسور اثر هال Hall sensor داراي سنسور A3142 است. سنسور A3142 همانند سوييچ اثر هال است. سنسور A3142 داراي پايه تغذيه و خروجي – output و زمين – GND است. همانطور که گفته شد ازسنسور A3142 جهت تشخيص ميدان مغناطيسي- Magnetic FIELD استفاده مي‌شود. با ايجاد ميدان مغناطيسي در نزديکي سنسور اثر هال، خروجي سنسور به پايين ترين سطح خود خواهد رسيد. در نتيجه با نزديک کردن يک شي مغناطيسي به سنسور، سنسور به پايين ترين سطح رسيده و ميدان مغناطيسي را تشخيص خواهد داد. سنسور اثر هال داراي سنسور A3142 و سه پايه به ترتيب Signal, VCC, GND مي‌باشد.

SENSITIVE HALL-EFFECT SWITCHES FOR HIGH-TEMPERATURE OPERATION These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet. The four basic devices (3141, 3142, 3143, and 3144) are identical except for magnetic switch points. Each device includes a voltage regulator for operation with supply voltages of 4.5 to 24 volts, reverse battery protection diode, quadratic Hall-voltage generator, temperature compensation circuitry, smallsignal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. The A3141– and A3142– are improved replacements for the UGN/UGS3140–; the A3144– is the improved replacement for the UGN/UGS3120–. The first character of the part number suffix determines the device operating temperature range. Suffix ‘E–’ is for the automotive and industrial temperature range of -40°C to +85°C. Suffix ‘L–’ is for the automotive and military temperature range of -40°C to +150°C. Three package styles provide a magnetically optimized package for most applications. Suffix ‘–LT’ is a miniature SOT89/TO-243AA transistor package for surface-mount applications; suffix ‘–UA’ is a three-lead ultra-mini-SIP. FEATURES and BENEFITS Superior Temp.
