Coz all I'm doing now is reading the files from /sys/class/hwmon/hwmon1/device/ namely adc0 and adc1 every 1 second and as they return numeric values, I'm just using that to turn speakers on/off. Can someone plz tell what they are actually, coz they are giving random results in different scenarios like I mentioned above and from what I found in the web, it is suppose to give proximity value.
