This paper explains the proposed architecture for a smart city using LoRa Technology. The framework is designed and implemented with two applications by using LoRa modules and LoRa gateway. The data from the end devices is reached to cloud via LoRa gateway; in this process end devices use only LoRa communication for sending data. The first application is monitoring environmental parameters like air quality and carbon monoxide content. This is implemented by creating a device with Dragino LoRa module and required sensors. The device will be sending the values to LoRa gateway by using LoRa communication. From Gateway the data will be sent to cloud where the administration can notice the heavily polluted regions and take necessary action.The second application is about providing safety for women and children. For this a wearable device is designed with Dragino LoRa GPS module. This device can be used to notify the location of the person in an emergency situation and can also notify if the person is out of the boundaries provided.
