This paper introduces a concept the design and implementation of a sensor networks for greenhouse gases monitoring. The sensor networks are deployed and monitored remotely on lifetime systems in a commercial, industrial area and smart cities greenhouse that produces lettuces in a tropical environment. The key issues are low-noise power supply, noise floor of sensor, high sampling rate, and the relationship among displacement, frequency, and acceleration. The sensor nodes were developed with the use of a micro-controller and sensor components . Real time data enabled the operators to monitor the operating parameters of the greenhouse and also to respond immediately to any changes in the controlled parameters
