I'm looking at conducting intermittent respirometry and with this, I need to control when the water pumps operate.
Essentially there will be 8 pumps in total - 4x type A + 4x type B.
Here is a link to the pumps if you require info on power consumption etc. :
A) Universal Pumps | EHEIM GmbH & Co. KG. Leading aquarium manufacturer.
B) EHEIM GmbH & Co. KG. Leading aquarium manufacturer.
Each metabolic chamber will be serviced by an A and B pair. The pumps will need to be operated in the following cycle:
- A is swithced on and runs for 10 minutes
- A is switched off and B is subsequently switched on
- B runs for 10 minutes and is switched off
A is then switched back on and runs for 10 minutes and the cycle repeats continuously.
To control this cycle I was hoping to use the following:
Will this be sufficient?
The following was suggested an alternative:
2x Gravity: 4 Channles Arduino Relay Shield - DFRobot
Any help will be much appreciated.
