Description

Circuit schematic like in Figure 1 above is Circuit Schematic Aircraft Hangar Fire Alarm System using Flame Detector and Arduino Uno. Flame sensor module used to detect the light and op-amp to control the sensitivity of flame detection. In aircraft hangar, this flame sensor is used to detect fire and provide HIGH signal upon the detection. Arduino Uno is used to reads the signal and provides alert by turning on buzzer and LED.

Flame Sensor 

A flame detector is one of the sensor that designed to detect and respond the presence of a flame or fire. In this aircraft hangar fire alarm system we used IR flame detector based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. This sensor module can detect infrared light with a wavelength ranging from 700nm to 1000nm and its detection angle is about 60°.

This sensor module consists of a photodiode (IR receiver), resistor, capacitor, potentiometer, and LM393 comparator in an integrated circuit. We can adjust the sensitivity by varying the on board potentiometer. We need voltage between 3.3v and 5v DC for this sensor, with a digital output. Logic high on the output indicates presence of flame or fire. Logic low on output indicates absence of flame or fire.

Working of Flame Sensor with Arduino

Arduino Uno is a open source microcontroller board based on ATmega328p microcontroller. It has 14 digital pins (out of which 6 pins can be used as PWM outputs), 6 analog inputs, on board voltage regulators etc.

Arduino Uno has 32KB of flash memory, 2KB of SRAM and 1KB of EEPROM. It operates at the clock frequency of 16MHz. Arduino Uno supports Serial, I2C, SPI communication for communicating with other devices. The table below shows the technical specification of Arduino Uno.

Solar Tracker Based on Arduino Uno with Servo Motor

Eltronicschool. - One application of system based on Arduino is used to control motor servo for solar tracker. This application is simply and arrange from the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light.

In this article we will show you the circuit schematic of Solar Tracker Based on Arduino Uno with Servo Motor, the description, and also the basic listing program of this application.

Description

Circuit schematic like in figure 1 above is Solar Tracker Based on Arduino Uno with Servo Motor.  This circuit using Arduino Uno board, LDR module, and Servo Motor. This circuit is using a standard servo that can rotate approximately 180 degrees (90° in each direction) and is controlled using the included Arduino’s Servo Library. 

Inside the code we use the “pos” variable to set the initial position of the servo to 90, the mid position. The 2 LDRs are connected to pin A0 and A1 on the board. The “tolerance” variable is used for allowing a small tolerance otherwise the solar panel would be continously adjusting its position.

In the setup() function we set the pins were the LDR are connected as INPUTs and position the servo motor at 90° then wait for a 2 seconds before the code execution inside the loop(). In the loop() we read the values received from our 2 sensors and adjust the solar panel based on these values.
