Re: RPI Zero W multiple sensors

sensors weren't working in this period of time?
you just put them there or you test them in these 4 weeks?

Re: RPI Zero W multiple sensors

In other words, one R3 and four ZWs is "cheaper" than four ZWs As cheap as possible, but not cheaper- Part 2 In the above consideration, I am assuming that after completing the project, you still need the Rpi3 to do maintenance and enhancement. This brings up another thing - time planning. If you h...

Re: RPI Zero W multiple sensors

If you are constantly weighing the pods, do you really need the flow meters? You know how much water you have let in to the pod from the sudden increase in weight. Yes should be given with both setups. thanks for you suggestion. yes, you are right, but the sensors only work in schedule, 2 to 6 time...

Re: RPI Zero W multiple sensors

Short Reply 1. Yes, RpiZW is powerful enough to handle the sensing and control, But I strongly suggest you to use Rpi3B+ for development, because 3B is much faster than ZW. 2. Rpi3B+ and MCP23017 can work together. 3. ESP8266-12/32 is strong in WiFi, but much weaker than RpiZ otherwise. NodeMCU for...

RPI Zero W multiple sensors

Hello there, this is my first project with Raspberry pi. i want to make a Testing chamber for growing micro greens(small plants). What this chamber does is following: 1- weigh the growing pods (pods picture is attached) - load-cell and HX711 (four of each of them) 2- control Humidity and temperature...
