Hello. I have bought a hall sensor module with 3 pins and I have no data sheet. But what I have found from google is that pin 1 = power, 2 = ground, and 3 = output. I post an image below how I have connected it so far. The problem is that the sensor seems to give no sign of working when a magnet is nearby. By using analogRead and the seriell monitor i can see the sensors value is between 892-893 (depending on resistor). What am I not understanding? Thanks in advance.
