Sensor-Hall

Language:	English  • 中文

Microduino-Hall 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 interface 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.

Program Open Arduino IDE, select File→Examples→Basics→DigitalReadSerial program examples, choose the 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 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 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. Project Purchase History Pictures Front Microduino-Hall Front Back Microduino-Hall Back
