Internet of Things (IoT) is expected to play a major role in our lives through potential systems of sensor networks surrounding our environment. These systems are designed to monitor vital physical phenomena, generating data which can be transmitted at cloud from where this information can be accessed through applications and further actions can be taken. This paper presents the implementation and results of an environmental monitoring system which employs sensors for monitoring temperature of the surrounding area. This data can be used to trigger short term actions such as remotely controlling cooling devices. The sensed data is uploaded to cloud storage and an Android application accesses the cloud and presents the results to the end users. This system employs Arduino board, sensors, Ethernet shield, ATmega 328 and Wi-Fi module. An Android application is used which accesses the cloud and displays results for end users.
