In this study, we design, develop, and demonstrate the performance of a portable sensor system for indoor environment, which is connected to the smartphone-based user interface for monitoring humidity and temperature. This sensor system consists several components those are packed into a single small box, namely: a Zigbee communication module, STM32L100 microcontroller, DHT11 temperature sensor, BL-5C rechargeable battery, and a charger circuit. The sensor system and the application are then tested to gauge the performance. Based on the test, the system is able to communicate with the smartphone through the host. In addition, based on 24-hour battery testing, the system requires less than 0.53958 watts to operate, thus achieving the low-cost target.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]DHT11,Humidity and temperatures,Indoor environment,Portable sensors,Smart homes[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]DHT11,Humidity and temperature,Indoor environment,Portable sensor system,Smart home[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This work is part of the “Internet of Things Devices for Smart Home System” project, which was funded by the Ministry of Research, Technology, and Higher Education of the Republic of Indonesia (Kemenristekdikti) for the decentralization scheme with Grant Number 009/SP2H/LT/DRPM/IV/2017 The sensor node along with the other end-devices have been exhibited in Centrum für Büroautomation, Informationstechnologie und Telekommunikation (CeBIT), on March 14-28, 2016 in Hannover-Germany Site: (http://www.pme.itb.ac.id/microelectronics-center-itb-on-cebit-2016-and-ict-roadshow/[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/IGBSG.2018.8393575[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
