  • Instructions of Use:When the sensor senses a magnetic field, the digital output is low and the light is on; if no magnetic field is sensed, the digital output is high and the is not lit.
  • Installation:It is provided with fixing bolt holes for easy installation and fixing.
  • Wiring Instructions:VCC -power positive,GND -power supply negative,DO -TTL digital output,AO -analog output (different distance output, different voltage).
  • High Performance:Using 3144E switch type sensor for Good temperature performance, it has high accuracy and high reliability.
  • Product Usage:Can be used for motor speed measurement, position detection, etc.

These work very well. The power light is always on and is extremely bright and green. The status light is also green and extremely bright, even on my 4.5 volt power supply. My small neodymium consistently activates it about 1 inch away. The description implies the analog out is a continuous changing values voltage, it is not! This makes sense as the 3144 is a switch and is not linear. AO is always .014v when activated and DO is alway .210v when activated. I was gonna knock off a star because of the false advertising by this seller but decided this review is for the device, not the seller.

These do not support or output linear signals. They are digital only.

The description says that the analog pin changes with the distance of the magnet, but that doesn't seem to be the case. It's very misleading how it is worded. It is partially my fault as the sensor is a linear sensor, but it still doesn't make sense to say you'll have different voltages for different distances when clearly its a linear sensor.

PCB is for linear sensor, but it comes with an open collector sensor. So, not linear output.What is the point of placing an open collector comparator in front or an open collector sensor?!If you need a hall effect sensor with soldered pins and unnecessary components, this works fine. Or as a cheap LM393 PCB.I will keep the PCBs and replace the sensors with the correct part number.So, if you need an open collector hall effect PCB with pins and indicator LEDs, get this. If you need a linear sensor, keep looking.1* because does not work as described.

Lo utilize para un tacometro con imanes, los detecta bien y el modulo es muy practico pues ya tiene salida 5v que lo hace util en arduinos o microcontroladores

Simple.. Advertised s linear sensor.. it is a switch only.. no analog.. will be returning..

Like other reviews have stated, the output is digital on/off only even though there is a A0 output and the product description says it has a variable analog output.Only reason this is 2 stars is because the part description does say it is a 3144E sensor which is a digital only sensor sensor. BUT a buyer shouldn't need to pull up datasheets to learn this - the description should not lbe incorrect as it currently is.
