Metal Detector is a security device which is used for detecting metals which can be harmful, at various places like Airports, shopping malls, cinemas, etc. Previously we have made a very simple Metal ...

Calibrate the sensors to ensure accurate readings. This involves setting baseline values for both the accelerometer (zero-point calibration) and soil moisture sensor (dry and wet calibration).

This remote-controlled metal detecting Arduino-powered robot is legit. If the video player is not working, you can click on this alternative video link . Everyone loves metal detecting.

There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.

This research study presents the design and implementation of a Metal Detector Robot equipped with a bomb detection capability, utilizing various technologies including the Arduino development board, ...

The TB-007 smart robot is equipped with a metal detector and is based in an Arduino with a motor shield which has the ability to control the two main motors, including a stepper motor and three servos ...

Arduino ADC is usable around 10/12 bits. That means it can measure up to 1024/4096 diferent voltage levels. Counting frequency instead can let you choose your own diferent measurement levels ...

Chipped radio-frequency identification (RFID) sensor systems have been studied for structural health monitoring (SHM) applications. However, the use of chip in sensor tags and its standardized ...
