Microduino-Hall is the Hall sensor module, which can detect magnetic filed.

Microduino-Hall sensor is based on Hall Effect, as one of the magnetoelectric effect, which was found by A.H.Hall in 1879 when he was studing metal’s conductive mechcanism.

==Features==
*High detection flexibility and stability.

==Specification==
*Electrical specification
**Output: Digital signal
**3.3V~5V operation voltage;
*Tech parameter
**Pin description: GND, VCC, signal output and NC(Empty).
**Digital output

**Size of the sensor: 5mm*5mm，
**Size of the board: 20mm*10mm
*1.27mm-pitch 4Pin interface connects with Sensorhub.

*Connection method
Note: Here we adopt digital signal output and need to use digital interfac to detect (D0~D13), which can connect to the number 3~9 pin of the Sensorhub, that is, D0,D2,D4,D6,D8,D10 and D12.

==Document==

*Schematic:'''[[File: Microduino_Hall.Zip]]'''

==Development==
===Preparation===
*Make sure you’ve built Microduino IDE or you can refer to: [Microduino Getting started]]
*Core board selection
**1.Adopt [[Microduino-CoreUSB]] or [[mCookie-CoreUSB]] as the core.
**2.Adopt [[Microduino-Core]] or [[Microduino-Core+]] as the core and [[Microduino-USBTTL]] asthe program download module.

===Program===

*Open Arduino IDE, select File→Examples→Basics→DigitalReadSerial program examples, choosethe right board, compile and download.

*int pushButton = 6; Define the input pin as D6, which can be changed by users according to personal needs.
*pinMode(pushButton, INPUT); Define pushButton as the input pin.
*int buttonState = digitalRead(pushButton); Read pushButton as the value of the input pin./

===Hardware Buildup===
*Connect the Hall sensor and Sensorhub to the D6 digital port, which is also the pin of “pushButton”mentioned above.
*For reference: [[Microduino-Sensorhub]]

*For reference: [[mCookie-Hub]]
[[file:mCookie-sensorhub_6.JPG|thumb|400px|center]]
*Connect the core, Sensorhub and Hall together to a computer with a USB cable.
*Select the right board and COM port, compile and download. You can refer to: [AVR Core：Getting started]]

*Open the serial monitor after download. The return value is “1” when it detects no magnetic field. By getting close to the Hall sensor with a magnet, you can get the return value “0” when detecting the magnetic field.

==Application==
[[file: Microduino-Hall-1.JPG|thumb|180px|center|Microduino-Hall Front]]

If Hall’s starting voltage is high level(V+), its surrounding magnetic field strength becomes intensified. When the intensity is bigger than Bnp, the output voltage between the two sides of the Hall sensor is the low level (V-). It keeps the same for the reverse.
*Suitable for detecting magnetic field and replacable switch function.
