Hi , I share with you this little box that can contain a welded SR04 HC sensor has a board Arduino mini pro .
The 2 holes for the sensor are largely sized to accommodate sensors that would not have the same spacing . There are often differences between 2 HC SR04 sensor .
I use this circuit with a relay on the electric power of my living room lamp to turn on or turn off .
Made in NYBI.CC
