I need a recommendation on a controller to use, which will automatically cause a water flushing system to turn on and off at certain times. I have played around with a LOGO! PLC but it is turning out to be very restrictive. Some qualifications:

  • Low power usage: the controller only needs to log data every hour or so. It is powered by a solar panel and a battery and cannot draw too much electricity (especially during the winter).
  • A way to configure flushing times. This either could be an attachable/onboard display and interface, or a way to connect externally. If going with the latter, it should act as a simple server and respond to commands, or host a webserver
  • The ability to log data and export it, over a network or onto external storage.

Bonus point for...

  • An integrated way to connect to a cell network (using a sim card)
  • Being really small!

Any advice or recommendations are greatly appreciated!

    If you're really good at programming check out the Raspberry Pi – Peter Zhu Jun 20 '16 at 22:00
  • The raspberry pi is practically a full blown computer which makes me worried about power consumption. I havn't looked that up though could be wrong – riverrun Jun 20 '16 at 22:12
  • The Pi doesn't draw that much power, and once it is configured you can down clock the CPU for further power savings. A lot of the power usage for the Pi is people connecting power drawing devices to all 4 USB ports. – cybernard Jun 20 '16 at 22:35
  • As cybernard has said it draws very little power. At normal clock speed and a USB wifi dongle attached, my Pi 2 Model B draws about 100mA at 5V when idle and up to 1A when under load. – Peter Zhu Jun 20 '16 at 22:38
  • alright ill consider it as an option then! – riverrun Jun 20 '16 at 23:08
