ABSTRACT

As increase in the environmental pollution for the sustainable and rapid growth of the world, air and sound pollution is major threat to the developing nations for the clean and healthy environment. Environment can’t be ignored as one of the environmental problems. The pollution cause damage to human health for a long time. So, in this paper we discuss about Smart Environment Monitoring (SEM). We use IoT technology for monitoring the environment parameters like Temperature, Pressure, Light Intensity etc. The data of the various environmental parameters are detected by the multiple sensors. Here we use LM35 Temperature Sensor, BMP180 Pressure Sensor, LDR Sensor, Gas Sensor, Soil Moisture Sensor. These sensors produce analog output. But here we use Spartan 6 FPGA which understand the logic 1 and logic 0, for processing the data. Since the output produced by sensors is analog in nature, we use Analog to Digital Converter (ADC) to convert the analog output into digital. After conversion, the digital outputs are sent to FPGA where the data is processed. Finally, the processed data is displayed on the 2x16 LCD Display. Here we use wiifi modem to broadcast the sensor data to ThingSpeak Cloud Network. Now we can access the data anywhere from the cloud. This feature makes the environment monitoring as smart.
