1pcs Hall Effect Magnetic Sensor Digital Output

Hall Sensor Motor Speed Measurement Module 3144E Product Description 

1. Basic Parameters 

- Product Name: Hall Sensor Motor Speed Measurement Module 3144E 

- Operating Voltage: 3.3V - 5V (compatible with most common circuit systems, no need for additional voltage conversion) 

- Indicator Lights: Equipped with both power indicator light and signal indicator light (real-time monitoring of power-on status and signal output) 

- Output Form: Dual output modes—digital switch output (0/1) for simple on/off signal reading, and real-time Hall analog output for precise analog data acquisition 

- Comparator Output: Adopts LM393 comparator (ensures clean signal waveform and stable output) 

- Installation: Comes with fixed bolt holes (easy to mount on devices or brackets, no extra tools required) 

- Size: 31.2 × 14.2 × 8.7mm (compact design, saves space for tight installation environments) 

- Weight: Approximately 2.4g (lightweight, won’t add extra burden to small equipment like motors or robots) 

2. Interface Description (4-Wire System) 

Wiring is simple and beginner-friendly, with clear function definitions: 

- VCC: Connect to the positive pole of the power supply (must be within 3.3V-5V to protect the module from damage) 

- GND: Connect to the negative pole of the power supply (ensure stable grounding to avoid signal interference) 

- DO: TTL switch signal output (can be directly connected to MCU IO ports, e.g., Arduino, ESP32, for quick digital signal processing) 

- AO: Small board analog signal output (voltage signal, suitable for connecting to ADC interfaces for precise analog value reading) 

3. Product Features 

- Wide Voltage Compatibility: Works with 3.3V-5V power supplies, matching mainstream microcontrollers and circuit systems—strong adaptability. 

- Stable Core Performance: Adopts 3144E switch-type Hall sensor, with reliable magnetic field induction and no signal drift during long-term use. 

- Intuitive Magnetic Feedback: Clear induction response—when a magnetic field is detected, the digital output turns low level and the signal light turns on; when there’s no magnetic field, the digital output turns high level and the signal light turns off. 

- Dual Indicator Design: Power indicator (shows if the module is powered on) and signal indicator (reflects magnetic induction status)—easy to troubleshoot and monitor. 

- Dual Output Modes: Digital output for simple speed counting or on/off detection, analog output for fine position adjustment or precise current measurement—meets diverse project needs. 

- Clean & Strong Signal: LM393 comparator ensures no noise interference, smooth waveform, and strong driving capability (>15mA), supporting direct connection to external devices. 

- Easy Installation: Built-in fixed bolt holes, allowing quick integration into projects without extra brackets.
