High sensitivity confirmed
I used this to detect small changes in magnet position for a robotic arm. The 1.4mV/G sensitivity allows for very fine resolution. Highly recommended for precision tasks.

Perfect for Arduino projects
This sensor works flawlessly with my Arduino Uno. The analog output is very stable and the sensitivity is exactly as described. Great for measuring magnetic field strength in linear applications.

Reliable and robust
We have deployed ten of these in our workshop for various demos. They have held up well over several months of continuous use. Excellent build quality for a module.

Great for learning
Bought this for a university physics project. It's easy to interface and the documentation provided by the seller was helpful. One pin was slightly bent but easily fixed.

Good value, needs calibration
Solid module for the price. You do need to calibrate the zero-point in your code depending on your specific environment, but once set up, it reads consistently. Shipping was fast.

Works great for current sensing
Using this to measure current flow by placing it near a wire. The linear response makes the math easy in the microcontroller. No noise issues observed so far.
Q: Is this compatible with 3.3V logic boards like ESP32?
A: Absolutely. The module operates on a wide voltage range from 3.3V to 5V, making it fully compatible with ESP32, ESP8266, and Raspberry Pi GPIO pins.
Q: How do I handle temperature drift in outdoor applications?
A: While the sensor operates up to 85°C, we recommend implementing software compensation or periodic recalibration if used in environments with extreme temperature fluctuations.
Q: What is the maximum distance for effective detection?
A: The effective distance depends entirely on the strength of the magnet used. With a standard neodymium magnet, reliable detection usually occurs within 10-20mm.
Q: Can this sensor detect both North and South poles?
A: Yes, since it is a linear Hall sensor, the output voltage will increase for one pole and decrease for the opposite pole relative to the zero-point.
Q: Does the package include a magnet?
A: No, the package includes only the Linear Hall Sensor Module. You will need to provide your own magnets for testing or application.
