Desain Sistem Monitoring Sistem Photovoltaic Berbasis Internet of Things (IoT)
Abstract: Photovoltaic (PV)
system is an alternative solution to provide electricity at rural area. A
common implementation problem at rural area is the PV power plant cannot be
monitored continuously. This research proposes wireless node for PV power plant
monitoring based on Internet of Things (IoT). Wireless node is aimed for
monitoring electrical parameter from the PV and environmental parameter
(temperature and solar radiation). Measured parameters are sent to the cloud
database to be accessible via the internet. The device consist of a sensor
module, signal processing module and wireless transceiver module. Wireless
transceiver module is an ESP8266 for connection to the IoT gateway and to the
internet. Unidirectional ACS758 is used for current sensing, which give a
reading error of 0.091 Ampere. For voltage sensing, a voltage divider is used.
It has a reading error of 0.063 Volt. DHT22 is used for temperature sensing.
Its reading error is 0.0097 °C. The radiation sensor has a reading error of 0.3
W/m2. Proposed design has been tested at Laboratorium of Energy Convertion,
Electrical Engineering Department, UNSOED, on 300Wp PV system. This device
provides reliable monitoring data transmission with average and deviation in
delivery time consecutively 57 seconds and 2 seconds.
