Obteniendo una mejor lectura de sensores en Arduino - E ...

· Esto sucede porque el sensor puede estar sujeto a variaciones aleatorias, y la suma de estas actúa como ruido. Existirán varias formas de reducir esta cantidad de ruido, y en este caso mostraremos 2 de ellas que pueden implementarse directamente en el código del Arduino. Primero estableceremos un umbral (o threshold) que será la diferencia entre un valor y otro del sensor sin …

Guide for MQ-2 Gas Sensor with Arduino | Random Nerd Tutorials

· The MQ-2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...
