The A3144 Hall Effect Sensor Magnet Detector Switch for Arduino is a switch that will turn on/off in the presence of a magnetic field. If no magnetic field is present, the signal line of the sensor is HIGH (3.5 V). If a magnetic field is presented to the sensor, the signal line goes LOW, at the same time the LED on the sensor lights up.?An onboard LED will also indicate the presence of a magnetic field.

KY038 is a highly sensitive sound detection module with Analog as well as digital output. This is an arduino compatible module. Using this module you can even measure the intensity of ambient sound. Most of the digital sound sensor module?just provides digital output i.e. if sound is present or not. But this Sound sensor module also provides and analog output voltage which is directly proportional to the intensity of the ambient sound.

Flex sensors are usually available in two sizes. One is 2.2 inch and another is 4.5 inch. Although the sizes are different the basic function remains the same. They are also divided based on resistance. There are LOW resistance, MEDIUM resistance and HIGH resistance types. Choose the appropriate type depending on requirement. ?Here we are going to discuss 2.2inch Flex sensor that is FS-L-0055.

A reed switch consists of two ferromagnetic nickel-iron wires and specially shaped contact blades (reeds) positioned in a hermetically sealed glass capsule with a gap between them and in a protective atmosphere. The glass capsule is filled with inert gas to prevent activation of the contacts. The ruthenium or rhodium plated contact surfaces are isolated from the outside environment, which protects the contacts from contamination.
