Circuit detectors and sensors based electronics projects
Circuit detectors and sensors based electronics projects like: metal detectors circuits, smoke detectors circuit, water detector circuit, light detector and other based sensors projects.
In some applications we need to detect the presence of the liquid is in some recipients . For this we can use a low level fluid detector circuit which can inform us when the liquid in recipients has low level . This LM1830 low level detector schematic circuit based on the LM1830 low level detector IC require very few external components and is very easy to build .
This metal detector it's based on the CS209A made by Cherry Semiconductor.The CS209A its a bipolar monolithic integrated circuit for use in metal detection/proximity sensing applications.The CS209A metal detector IC contains two on-chip current regulators, oscillator and low-level feedback circuitry, peak detection/demodulation circuit, a comparator and two complementary output stages.The oscillator, along with an external LC network, provides controlled oscillations where amplitude is highly dependent on the Q of the LC tank.
