Detailed Description

Tiny and thin hall effect sensor/switch board is very sensitive and simple to use. Just connect red lead to (+) 5VDC, black lead to the (-) of the 5VDC and any load that requires up to 5VDC @ up to 0.250Amp to the yellow lead and black lead. As soon as the supplied magnet is brought near the 1.16" x 0.33" x 0.04" PC board your load will be activated-remove the magnet and the load turns off. Works with motors, LEDs, relays, low voltage solenoids, lamps, etc. Our tests indicate a range of 0.7 inches between supplied magnet and board!
