Why analogue to digital conversion is needed when computers are used to control a greenhouse?

Analogue to digital conversion is essential in greenhouse control systems because most environmental variables, such as temperature, humidity, and light levels, are measured in analogue form. Computers operate on digital data, so converting these analogue signals into digital formats allows for precise monitoring and control. This conversion enables automated systems to make real-time adjustments based on accurate data, optimizing conditions for plant growth and ensuring efficient resource use. Ultimately, it enhances the greenhouse's overall performance and productivity.
