10pcs Hall Sensors Module 3144E Hall Switch Speed Magnetic Swiches Speed Counting Sensor Module for Arduino Smart Car
10pcs Hall Sensors Module 3144E Hall Switch Speed Magnetic Swiches Speed Counting Sensor Module for Arduino Smart Car
Product Features
- This sensor switch can be used for motor speed measurement, position detection, etc
- Using 3144E switch type sensor for Good temperature performance, it has high accuracy and high reliability.
- Wiring Instructions:VCC -power positive,GND -power supply negative,DO -TTL digital output,AO -analog output (different distance output, different voltage).
- Work Voltage: 3.3-5V
- When the sensor senses a magnetic field, the digital output is low and the signal light is on; if no magnetic field is sensed, the digital output is high and the signal is not lit.
