BSTRACT
The article covered the process of developing a wireless temperature monitor with a radio module for
researching solar cells under heat and humidity conditions. Through this, the possibility of using the
equipment and panels installed in the solar power plant in the organization of technical service was
considered. The possibility of improving the quality of service has increased if the workers know the
temperature and humidity of the solar cells while monitoring the amount of energy produced. In this
article, we have implemented wireless communication between two Arduino microcontrollers and
temperature and humidity monitoring using an NRF24L01 radio module, DHT11 sensor and display.

Today, the use of solar cells is increasing with fast
photos, their performance is strongly dependent
on temperature and humidity, and continuous
measurement of these parameters causes some
inconvenience. Therefore, it helps to monitor

environmental changes in convenient conditions
using wireless communication tools.
To do this, we connect the DHT11 humidity and
temperature sensor to the transmitter Arduino
microcontroller with the NRF24L01 receiver
module and connect the receiver Arduino
microcontroller to the Arduino microcontroller
with an LCD display to display the information
along with the wireless receiver NRF24L01
module for temperature and humidity data.
Figure 1. NRF24L01 radio module.
These radio modules are very popular among
Arduino project makers. The nRF24L01 is used in
a variety of projects that require wireless control
because each module can transmit and receive
data. These modules are inexpensive advanced
models that can transmit data up to 1200 meters
and can be used with any microcontroller.
We assembled two separate circuits to establish
wireless communication between two NRF24L01
receiver modules. The first circuit shown in the
image below is the final part of the transmitter
and consists of an Arduino Uno, an nRF24 and a
DHT11 humidity and temperature sensor.

Several factors affect the efficiency of a solar cell,
including heat, dust, humidity, external
temperature, and other factors that affect the
recombination current in the PN junction. When a
solar cell is too hot, the FIC that it produces
electricity decreases, resulting in reduced
efficiency and accelerated battery degradation.
Humidity, in turn, can reduce efficiency. Water
droplets and water vapour can collect on solar
panels and reflect or refract sunlight from solar
cells, reducing sunlight penetration and
electricity production. Constantly hot and humid
weather can shorten the life of solar cells. This
applies to both crystalline silicon elements and
thin film modules, but cadmium telluride (thin
film) solar cells perform about 5 per cent better in
hot, humid climates. Solar panel manufacturers
are well aware of the effects of humidity on solar
cells.

temperature and humidity are installed on the territory of the Fergana Polytechnic Institute.
The device developed by us is installed in the 80
KW solar power station located on the territory of
the Fergana Polytechnic Institute. It allows you to
use it to organize technical maintenance of the

service.
The results showed that information about the
temperature of solar cells was obtained from a
distance of 100 meters. In the future, it is planned
to put the obtained data on internet hosting and
make it available for everyone.
