Grove Computer Controlled USB Submersible Water Pump

This is a Submersible Water Pump designed to be controlled by a Raspberry Pi or an Arduino. The product includes a USB PowerControl board which controls the USB power input to turn the Water Pump on or off by a control signal a GPIO on the computer. This product can be used with or without Grove connectors as you can connect jumper wires to the pins inside the Grove connector. Using this product requires NO soldering.

It can be used for for any project you want to pump water under computer control. Some applications are: Plant Watering (such as SmartPlantPi), aquariums, various chemical processing projects.

This product contains:

  • USB PowerControlNE
  • USB Powered Submersible Pump



The software to use the USB Controlled Submersible Pump is simple. Two GPIO lines are connected (either through a Grove connector or jumpers) and you can control the devices per this table. In most computer controlled applications, LIPOBATIN is left unconnected. See the specification. SwitchDoc Labs is providing a simple set of drivers for the Arduino and Raspberry Pi. See example code in SmartPlantPi, a Raspberry Pi Watering System.


USB PowerControl


The USB PowerControl board is a USB to USB solid state relay. It is is a digitally controlled power switch for your Arduino or Raspberry Pi. It is a Pi On and Off switch.

Anything you can plug into a USB port can be controlled with USB PowerControl. It's easy to hook up. You connect a control line to the Grove connector (two GPIO lines) or the output of a LiPo battery to the LIPOBATIN line and if the line is LOW (< ~3.3V) the USB Port is off. If it is HIGH (above 3.8V) the USB Port is turned on and you have 5V of power to the USB plug.

We have now added a Grove Digital Input that allows you to control the USB PowerControlV2 using two GPIO Lines (one enable and one control line) to switch on and off from a Grove Digital Port. The Grove Enable Line, when high, disables the LIPOBATIN line and makes control of the device under the Grove Control Line. When the Grove Enable Line is low, the LIPOBATIN line controls the relay as in the original USB PowerControl. The Grove Enable Line is pulled up by a 43K resistor so if it is disconnected, the USB PowerControlV2 is compatible with the original USB PowerControl.

Grove GPIO Control Circuitry for NE

This circuitry is provided to allow the USB PowerControlV2 to be controlled by either LIPOBATIN or the state of the CONTROL Line (J3 Pin 1). ENABLE (J3 Pin 2) controls whether the USB POWERCONTROLV2 is switched by LIPOBATIN or the CONTROL line. Remember that LIPOBATIN is not a digital input. It is designed to look at the voltage level of the battery.

The truth table for the USB PowerControlNE V2 is given below:






Turn your raspberryPi/arduino on and off using this solid state relay. Use a GPIO line, use a WatchDog timer, or use a different voltage level to trigger the relay.
This board was initially designed to sit in-between a Solar Power Controller (such as SunAir/SunAirPlus) and a Raspberry Pi / Arduino. The input to the board was designed to come directly from a LiPo battery so the computer won't be turned on until the LiPo battery was charged up above 3.8V. We provide a hysteresis circuit so the board won't turn on and then turn immediately off because the power supply is yanked down when the computer turns on (putting a load not the battery). This really happens!!!! You kill Raspberry Pi SD Cards this way.
The software for this device is simple. You use one GPIO line to turn it on or off (or connect it directly to your LiPo battery for automatic control!). It controls the 5V line that powers a USB device plugged into the female USB A power end of the board.
