Ozone sensor, calibration and Sketch - Sensors - Arduino Forum

06/06/2021· I’m working with the Ozone sensor model Mq-131 and one module KS123-35Y500K in an Arduino UNO. A link to that board would help. This library makes the conversion to ppb. Remember the conversion of the read analog value is also based on the humidity of the air around the sensor as well as the type of sensor (there are two versions named MQ131 ...

digitalRead and level probe sensor - Arduino

05/05/2021· I'm still here... Now I've problem with the digitalRead... I've a level probe that "returns" HIGH when the water level is below the threshold else LOW... The probe works also with 5v so I connect a wire to the 5v arduino's pin and the second wire to the pin 7 The sketch correctly recognizes when the probe is HIGH, but when the probe is LOW the sketch starts to "loop" reading LOW and HIGH when ...
