HARDWARE

The hardware used for this project is:

• CDPD Modem Raven II (Airlink)
• CR10X
• Pumps
  - For higher capacity pumping requirements: "Rule bilge pump" 360 gph 
  - Small pumps: SP200 from APT Instrument
• Rain Gauge. Tipping bucket rain gauge from Rainwise

• Relays. Solid state Crydom DC60S3. Note that the common contact relay does not work in this application as it is driven by a CR10 control port which has a low power capacity. Contact relays require up to 60 mA to operate with 5V input. Solid State relay only requires 2.2mA for the same 5V input.

• Solar Panels. 2x20W solar panels are being used. See the performance of those in a graphic below. On will be in the shade most part of the year, so a separate one was installed 300 ft away from the site where is not shaded by the trees

• Stage Encoders. Enviro-Systems (JGS Enterprises) 

CONNECTIONS

General connections and connections in each particular enclosure are shown below:

Relays driving the bilge upstream, bilge downstream and small upstream pumps are located in the upstream enclosure. The connections look as follows:
