DIY Doser with power failure alarm

joyz76 · 1 May 2020

Hi guys, I wanted to share with you my Arduino DIY Dosing Pump.
I worked on them for some time so i have many versions of it, but the final one is great and can dose with a great precision (0.1 ml).
Here a pic of the finale work:

Build on Nodemcu, a ESP8266 chip based they are controlled via Web:

You can also log all your test results on the website and have graphs

You have an alarm when your containers are going out of liquids:

And you have alarms on blackout too:

You can find all the step by step instruction and the software at:
Feel free to ask for details, or help.

Que buena la pagina joyz76, gracias por compartirla

Como dice el compañero, un buen tutorial para los manitas, pero con los precios que hay de dosificadoras baratas, tipo jebao, por menos de 100€ con cuatro canales, no merece la pena la inversión de más de este precio para cuatro canales y que además tiene que estar permanente conectada al servidor de la aplicación para dar servicio, mientras que estas pueden trabajar sin wifi o con ella según modelo.
Pero gracias joyz76 es un buena aportación para los amantes del DIY
