2 x Distance sensor with mounting bracket

Ultrasonic ranging module HC – SR04 provides 2cm – 300 cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receiver and control circuit. The basic principle of work:
(2) The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
(3) IF the signal back, through high level, time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (340M/S) / 2,

You will need 4 very small screws to attach HC-SR04 to the mounting bracket.
I use a small amount of hot glue instead.
Works like charm.
