A low power, low cost system and method for the detection of flow disturbances in a fluid dripping system is disclosed. In one embodiment, a light source and a light detector configured to monitor the amount of light passing through a droplet while the droplet is suspended and later falls from the tip of a tube. In another embodiment, dripping fluid is monitored from a system maintained part of the time in a sleep mode to conserve power, the system waking up at predetermined times to determine from detected light whether the monitored system is functioning properly.
