 Bigger Bigger  Smaller Smaller  Reset Reset

 Hello there !

I am trying to explore the possibilities to use HC SR-04 sensor module (http://letsmakerobots.com/node/30209)
 for Water level monitoring.The main problem I am facing is to protect it from moisture and make it water proof. The pcb can be protected by using epoxy but what about the speakers.

Kindly help

if you cover them up, the sensor is pointless, so i guess you cant do much IMO
