>> ALTRI TIPI DI SENSORI Hall nel settore 'Sensori' del nostro negozio <<
Il dispositivo include un generatore on-chip tensione di Hall per il rilevamento magnetico, un amplificatore che amplifica la tensione di Hall, un trigger di Schmitt per fornire isteresi di commutazione per il rumore , e un open-collector in uscita
The A3144 is a hall effect switch. It is a 3 pin device. When you are looking at the side with writing on it, which also has bevelled edges the pins are, from left to right, 1 (VCC), 2 (Ground) and 3 (Output).
This device has a built in voltage regulator and can run at voltages from 4.5V to 24V.
When a magnet comes sufficiently close the output goes low. To use connect the output pin 3 to VCC via a 10K or similar pull up resistor. If using with a Raspberry Pi, pull up to 3.3V.
