NEW BIG Candy Corn proximity sensor switch is just as great as the LITTLE Candy Corn proximity sensor switch, but almost twice the size and with new features! BIG Candy Corn is highly sensitive and does not require a physical touch from the user to activate. Simply wave a hand or move your body within 1-in/2.5-cm of BIG Candy Corn and it activates..
Auditory beep and visual feedback can be turned on and off.
Larger activation area that is approximately 3.5-in/9-cm wide (80% wider than the LITTLE Candy Corn!).
Easier to activate – activates when the user is within 1-in/2.5-cm of the switch top or with a light touch.

indicators to reveal brightness level, battery level, and charging status..

Proximity switch is a position sensor with switch output that can be connected with microcomputer.
It also can drive directly from, electromagnetic relays, counters and contactor to achieve automatic control purposes.
It is a component widely used in automatic control industry for detecting, controlling, and non-contact switching..
When proximity switch is close to some target object, it will send out control signal..
It's widely used in machine, paper making, light industry for limiting station, orientation taking count, speeding trial etc..

Metal Detector PRO is an extremely useful application for your android phone.
Application Metal Detector PRO uses built-in magnetometer that can measure electromagnetic field (EMF) level in your surroundings..
This application detects electromagnetic fields there around your smart phone and tells you if there are metal close..
Meta Detector app uses built-in magnetic field sensor. Please check in your phone specification if your device is equipped with one..
The app detect ferromagnetic metals which means that only detects those which generate magnetic fields..
The metal detector app works also through walls so it can detect hidden electrical wires, studs and metals..
The magnetic field intensity is presented on a magnetic field intensity chart..
The magnetic field meter will play sound and vibrate if magnetic field generation object are detected in proximity of the app..
Please note that the accuracy depends entirely on the magnetic sensor (magnetometer) in your device and might be affected by electromagnetic waves generated by nearby electronic equipment..
