Aquarium Automatic Top Off System

-

i have been searching , not finding having done want do.  not sure if better suited project arduino or pi seeking little guidance. dumb version simple , have worked out already.  4 switches, dual relay board, dual output power supply , 12v dc pump.

two switches in series aquarium itself.  1 water level normal open, closes when water level drops.  second closed , above first...it opens water touches prevent on fill should primary switch fail open again @ normal water level.

in top off reservoir there 2 more switches @ same level.  1 normal closed , in series 2 above , 4th switch solo , closed.  reservoir empty opens 1 of 3 prevent pump running dry.  4th closes , sets off flashing led , chirping alarm.

all of simple enough, done, tested , functioning. 

where "smarts" come in notification , data gathering.  have 0 idea how or done. 

  • in addition basic alarm described above 4th switch trigger text alert phone and/or email.  either device on wifi network or drop network cable.  stop here , happy why stop right?
  • it nice set time run limit on pump secondary safety upper switch.
  • monitor how pump runs , how long.
  • if timer or upper switch kills pump send alert , maybe keep offline till manually.
  • what water temp , ambient air temp when pump runs...and maybe measure humidity well.



so, thoughts?

hi new arduino , trying write code of temperature controlled fridge can adjust pot , temp in fridge changes lowest setting -15 , highest setting 30degrees. the temp drops below input pot im trying make compressor turn on , light show compressor on. new @ , im still not quite sure im doing. error below keeps popping , im not quite sure whats wrong code. im hoping on close path how should have done it, how fix error appreciated. arduino: 1.8.4 (windows 10), board: "arduino/genuino uno" c:\users\admin\appdata\local\temp\ccfcxdpc.ltrans0.ltrans.o:(.rodata+0x6): undefined reference `print::write(unsigned char const*, unsigned int)' c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/4.9.2/../../../../avr/lib/avr5/crtatmega328p.o:(.init9+0x0): undefined reference `main' collect2.exe: error: ld returned 1 exit status exit status 1 error compiling board arduino/genuino uno. this report have more information with "show verbose output during comp

esp8266 (nodemcu 0.9) client.write très lent ???

bonjour à tous, j'essaie d'établir une communication entre une carte nodemcu exp8266 et mon pc en wifi via les sockets wifi. cela fonctionne plutôt bien mais le problème vient de la lenteur des instructions liés à l'écriture : par exemple client.write(buf) qui s'exécute en 200ms et est donc bloquante. comment peut on faire pour réduire ce temps d'écriture car c'est vraiment handicapant. merci a+ antoconde vous êtes sous windows? si oui c'est sans doute dû aux delayed acks quote if make network trace network sniffer such microsoft network monitor, tcp server sends tcp ack segment last tcp segment in tcp data stream in delayed acknowledgement timer (also known delayed ack timer). default, windows operating systems, value timer 200 milliseconds (ms). faut éventuellement gérer l'agrégagtion d'ack dans votre code pc en contournant les infos systèmes. ça améliorera un peu les choses - mais le problème est côté pc pas esp (pa
