Confirm 5V supply is reaching the sensor. Replace the A0 pin connection with another analog pin and update it in code. Check if the sensor’s AOUT pin is functional.

Ensure all jumper wires are firmly connected. Use short wires to reduce noise. Add a 100 nF capacitor between the analog pin and GND to stabilize readings.
