Simple Metal Detector Electronic Production Kit DIY Teaching Spare Parts Technology Training Welding Metal Detection

Features: 1: Simple aembly 2: The appearance is small and exquisite 3: Wide range of uses, game entertainment, security , search of metal products on the body, etc. 4: High sensitivity 5: Learning DIY Kit Specifications: Supply voltage: DC3-5V Battery model: CR2032 (delivery without battery, customer needs to prepare) Dimensions: 14.9*2.2CM Uses: game entertainment, security , search for metal products on the body, etc. Purpose of this Metal Detector Princle : Example 1: If you want to detect whether there is a car paing by on a certain road, because the height of the car chais is 0.5 meters or more from the road, and the cement will be buried at a depth of 5-10CM, so you can bury a coil with a diameter of 1 meter on the ground. Stable, accurate and reliable detection of whether there is a car on it is of great practical value in highway traffic statistics and statistics on prohibited parking areas. Example 2: A r is required on each floor of the elevator controller to detect whether the elevator has reached the stop position. If a mechanical travel switch is used, there will be life and reliability factors; if a photocoupler is used, there will be a long time Dust deposition fai; therefore, the only way is to install a metal detector to determine whether the circuit is on or off based on the presence or absence of metal. This will have high practical value in many equment and hines.
