The entire sensor package can be fitted inside a PVC pipe, along with an XBee radio to provide ADC and radio modem capability. An attached small-diameter silicone tubing lead provides differential pressure for the pressure sensor and a duct for the XBee antenna wire. This complete package can then be anchored directly in the stream bed and the silcone tube brought to the stream bank and buried. The XBee radio can be put to sleep to enable a (4) D-cell battery pack to last ~60 days.
