3.7.2 Proteus Simulation

Figure 3.6 shows the connection of solar module and sensor parameter. The temperature of the solar sense by temperature sensor LM35. The temperature of the solar can also be used with humidity sensor which it can sense the both humidity and temperature of solar surrounding. The LDR act as an irradiance meter to detect the light intensity from the solar panel. However, the irradiance meter is impossible to perform in this project because of its higher cost. The variable resistor act as voltage sensor in order to monitor solar power energy.

3.8 Hardware Testing

3.8.1 Interfacing of Temperature Sensor LM35 and Displaying Output on 16x2 LCD with Arduino.

This section shows the interfacing of temperature sensor, humidity sensor and displaying output on 16x2 LCD with Arduino. In this project, the LM35 sensor are used to sense solar temperature and DHT11 are used to sense the humidity of solar panel. This sensor are basic and very popular sensors. The reason for using this sensors are because it is very affordable and has very minimal connection. It is also give output directly and degree centigrade. In this project, it will display the temperature and humidity reading from LM35 and DHT11on the LCD screen. LM35 is an analog sensor. From the datasheet shows that LM35
