Therefore, this research aims to develop a monitoring system to determine soil moisture, soil pH, and light intensity in real-time. This research uses NRF24L01 module, which enables wireless communication between sensor nodes and gateway. Sensor tests for soil moisture, soil pH, and light intensity as well as data validation at the gateway and transmission range testing were conducted through ten experiments on sensor nodes and gateways and thirty experiments to measure transmission range at distances of 40 m, 100 m, 150 m, and 200 m with or without obstructions such as trees and buildings. The test results show that the soil moisture sensor has an average error of 5.765%, soil pH 2.515%, and light intensity 0.075%. Thus, the Gateway is able to transmit data with 0% error for soil moisture, soil pH, and light intensity. Test results at a distance of 40m showed 100% data transmission with and without obstructions. However, the received data dropped by about 7% at distances of 100m, 150m, and 200m, with no obstructions, and 27% - 47% when obstructions, such as trees and buildings, were present due to signal interference.

In this paper, a bi-directional coplanar-waveguide (CPW)-fed antenna with circular polarization (CP) is investigated as a radio frequency identification (RFID) reader antenna. The antenna geometry is square and printed on one side of the FR4 substrate only, which consumes an overall dimension of 60×60 mm2 with a thickness of 1.5 mm. The simulated and measured parameters of the antenna are in agreement with an impedance bandwidth (S11<-10 dB) of 40.2% (2.18-3.28 GHz) and ARBW (<3 dB) of 28.3% (2.03-2.7 GHz), respectively. The peak gain of the proposed antenna is 3.17 dBi in both ± z directions. An Arduino UNO-based open-source microcontroller setup is used for studying this antenna as an RFID reader antenna, along with a wireless module NRF24L01 module at 2.45 GHz with an external antenna (tag). The path loss between the tag and reader antennas is found to increase in the desired band due to interference exists.

&lt;span id="docs-internal-guid-c15e9fd9-7fff-537c-ddf2-1938aca07829"&gt;&lt;span&gt;Electrical energy can not be separated from the name kWh Meter, a tool used to measure and record the amount of electrical energy usage has a shortage of kWh meters can not be monitored remotely how much energy is used, so it is rather inconvenient for PLN officials to check the use of electricity for postpaid customers. This research was conducted to design a prototype of a wireless electrical energy transmission system and design a wireless electrical energy recording system using the NRF24L01 wireless transmitter module and the PZEM004T kWh meter module. The design in this study uses the principle of electromagnetic induction to transfer electrical energy at close range, while to transmit data, the authors use the NRF24L01 module.
