Atlas Scientific Embedded Dosing Pump 0.5ml/min - 105ml/mins

These pumps work perfectly in conjunction with the Atlas Scientific EZO boards and a Raspberry Pi. You will want to test your automated system before installing this into an existing hydroponic system.

This was pretty simple to setup once I read through the manual. It is working after just a few minutes of setup

Although it is present in the instructions the order came without plastic inline tubing connectors, we bought 4 pumps so we need 8 connectors. Buying them separately in the local store can cost you 11$ for 1 piece.

I can't say enough positive things about this little peristaltic pump. It's quiet. It's dead simple. It has a built-in microcontroller and motor controller, so it interfaces with any of the hobbyist micros over UART or I2C. Just supply 12-24V. The serial interface even uses some human-readable strings! How handy is that?! It has multiple different dispensing modes and a built-in calibration routine. After calibration, water was being dispensed to within 0.1g of my requested target from 1g up to 120g, and that error could have easily been in my balance. And, unlike nearly any other product in this space, the documentation (on Atlas Scientific's website) is fantastic. The supplied data interface cable is of high quality, with a thick, flexible jacket. It's readily apparent that Atlas Scientific cares about their products and the customer experience.I guess, if I had to say something negative, I'd say it doesn't pump very quickly; 100 mL/min is hardly a flood.I'll probably be buying a dozen more.
