Abstract: 
  
  Our   goal is to design a remote solar-powered water pump controller. The   system consists of two parts: 
  transmitter and receiver/pump end. The   transmitter end consists of a microcontroller, a float sensor, a 1.5W   
  solar panel and an RF transmitter. The receiver/pump end consists of a   microcontroller, a water pump, hose, 
  two 40 W solar panels and an RF   receiver. A steel frame is built to hold the solar panels, and a power   supply
circuit is built to power the microcontrollers. In software   development, the microcontrollers will be programmed 
to enable   communication over a 433 MHz channel. The pump will draw water from the   pump end to the transmitter 
end when there is enough sunlight and the   storage container is not full. The transmitter will communicate the   
state of the container wirelessly to the receiver.
