The following table shows the power consumption of the Plug & Sense! Smart Water Xtreme sensor probes. Remember that the sensor board can be completely disconnected by turning off all sensors, reducing the consumption to zero.
Added to that, some sensors are quite complex and they have various working modes, so the power consumption could vary. The values shown in the table are averages when the sensor is being read by Waspmote.
