Detailed Description

Arduino Hall Effect Switch Module
Module can detect a small magnet at a few millimeters. The A3144 Hall effect sensor is connected to a LM393 voltage comparator IC with adjustable trigger level (R6). The LED indicator turns off when a magnet is detected (Output LOW when in Mag field). The sensor has two flat sides and is polarity sensitive. One side detects the north pole and the other detects the south pole of the magnet. The output can be connected directly to a micro-controller port. Ideal to use as a limit switch on your DIY 3D printer, robot or Place a magnet on motor shaft and use to measure RPM.
Power: 3.3V to 5VDC
Supply Current < 9mA (LED off)
Output: Digital TTL Open Collector Current sink 20mA
Magnetic Sensitivity 50 – 350 Gauss
Sense Distance: Depends on Magnet strength
3Pin .1Pitch Header for Power & Output
L: 1-3/16” W: 5/8” T: 5/8” WT: .02

As an example:
   ABS plastic contains styrene
   PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
   electrolytic capacitors can contain Ethylene glycol
   Brass can contain Lead
   flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
   Aluminum alloys can contain Chromium

To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
