Analog read value floating - Programming ... - Arduino

May 05, 2021 · Hi guys, I follow this page "SHARP GP2Y1014A0U Demo" to made a PM 2.5 sensor monitor, and I find the analog read issue. When I follow the information to connection the circuit and using the example code try to show the PM2.5 value, I can find the PM2.5 value in the IDE serial monitor, but the value look is wrong. When I remove the PM2.5 sensor and using wire connect the analog pin to …
