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 the 4 growing pods with load-cell and HX711 (four of each of them)
2- control Humidity and temperature with DHT22 attached to relay board to turn on or off the heater and humidifier (one DHT22) and also turn off and on the exhaust fan.
3- Control light hours (turn on and of in specific time) with relay
4- control growing medium moisture with capacitive moisture sensor (CSMO v1.2) - sensor controls the solenoid valves to water the pods with relay board whenever medium is got dry. since out pot signal is analog i use MCP3008 to convert it to digital
5- each pod has flow meter attached to its watering pipes to measure how much water is used.
to be short i have the following sensors that i want to control with RPI zero W:
4* Load cells (YZC-133) with 4 HX711 for each one
4* Solenoid valves.
4* Capacitive moisture sensors (CSMO v1.2) with 1 MCP3008
4* Flow meters
1* Exhaust Fan
2* 4 Channel relay board
(schematic wiring is attached )
So here are my questions:
1 - could R PI zero W handle the processing load of controlling these sensors?
2- is it possible to do this project with ESP32? could ESP32 handle these sensor's processing load?
i appreciate any suggestion for doing this project.

Thank you all in advance.
