20191120· Mengenal Sensor MQ2 / MQ2. MQ2 adalah sebuah modul sensor yang dapat digunakan untuk mendeteksi asap atau gas yang mudah terbakar pada konsentrasi antara 200 ppm – ppm. Apa itu ppm ? ppm adalah singkatan dari “part per million” yaitu suatu satuan unit yang menyatakan jumlah atau konsentrasi zat dalam setiap 1 sama dengan satuan persen (%) yang artinya …
20160223· MQ2 can sense methane(CH4) upto 20000 ppm where as MQ5 can sense CH4 only upto 10000 ppm. The difference between MQ5 and MQ2 therefore lies in its range of values. We choose the right sensor based on the application requirement; say for example – We can not choose MQ2 for sensing low levels of LPG in the range of 700 ppm because MQ2 is insensitive low levels of LPG (its …
