Sensors and equipment used in a greenhouse (aeroponic system)

1. Temperature Sensor.

• In the aeroponic system, the temperature is one of the critical factors significantly determining plant growth and development.
• A reduction in temperature below the optimal conditions often results in suboptimal plant growth.
• A different cultivar requires a different temperature level for the photosynthesis process and growth, which can advance the plant growth stage. It will eventually bring us substantial economic benefits.
• In the aeroponic system, the optimum growth chamber temperature should not be less and more than 4 and30°C, respectively, for successful plant growth.
• The temperature fluctuations of aeroponic growth chamber can significantly affect the root growth, respiration, transpiration, flowering, and dormant period. Therefore, the temperature sensors can be used to monitor the temperature fluctuations of the aeroponic system.
• At present, temperature sensors are used in many applications like environmental controls, food processing units, medical devices, and chemical handling.
• The temperature sensor is a device mainly composed of thermocouple or resistance temperature detector.
