There is often such a demand: the laboratory needs to monitor the temperature and humidity conditions, and remote control is required Click the switch, how can you develop a software and hardware system that you can develop again? As a technology of your own. Welcome to advise!"
Usually a single person doesnt develop all the sensors , the controllers, and output devices on their own.
For a professional lab delivering a volume commercial product, usually you would select industrial components that meets construction, safety and reliability standards.
That said, pick a PLC, a thermostat with humidity sensor. The thermostat provided the HMI function.
The PLC would drive the heaters, water solenoid, and fans directly, air conditioning compressor motor, or can also add variable speed drives for fan control.
Depending on lab size, you may need power delivery equipment for your components depending on the type of lab.
