Smoke sensor arduino

In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. In this project, we will go over how to build a smoke sensor circuit with an arduino board. The smoke sensor we will use is the MQ-2. This is a sensor that is not only sensitive to smoke , but also to flammable gas.

The MQ-smoke sensor reports smoke by the voltage level that it outputs. MQSensor is one of the most commonly used Sensors throughout the world. This Sensor is most commonly used for the Smoke and Gas detection. A 16xLCD is used for displaying the PPM value of Smoke. And an LM3IC for converting smoke sensor output into digital form (this function is optional).

MQ-senses Carbon Monoxide and this MQ-senses Smoke and flammable gases. The sensor is one of the MQ series gas sensors. Check out the demo here. Featuring a solar charger kit from Voltaic Systems.

The resistance of the sensor is different depending on the type. It starts reading data from the MQ-sensor. The data is read from the analog output pin of the sensor. The read data is in the form of an analog voltage which is digitized using inbuilt ADC channel. The Smoke sensor we used is the MQ-1sensor.

MQgas sensor is also sensible to LPG, Alcohol, and Methane etc. Smoke Detectors are very useful in detecting smoke or fire in buildings. Identica 11views. It has high sensitivity and fast response time to measure and take the data.

Sensitivity can be adjusted by potentiometer behind it. At home we have wood heating system. I wish to display the smoke gas temperature on my node-red dashboard in form of a gauge. I want it connected to my raspberry pi. The project is built on Arduino Pro Mini and MQ-gas sensor is used to detect smoke.

The MQgas sensor detects the concentration of gas in ppm and outputs analog value which can be converted to digital measure using inbuilt Analog to Digital Convertor of Arduino. Smoke Sensor Module General Description: A smoke sensor is a device that senses smoke , typically as an indicator of fire. This MQ1gas sensor is sensible to LPG, Alcohol, and Methane etc. MQConnections with Arduino.

LPG Sensor with MQ-and Arduino The MQ-is a semiconductor device for detecting the levels of propane and butane in the air. Since liquefied petroleum gas (LPG) is composed of these two gases, then the MQ-can be used as a LPG sensor. I managed to get it to display correct temp on Arduino IDE on my windows PC. MAIN CIRCUIT DIAGRAM OF FIRE SENSOR ALARM The main diagram of this project can derive all the essential part which is used for better technical aspect. LMTEMPERATURE SENSOR AND ARDUINO.

GSM MODULE AND AURDINO UNO. The LMis the main temperature sensor. It connected to the Arduino UNO.

The function is when smoke sensor detect a smoke the arduino uno will command the gsm to send a message. Please i need your help. Just a codes for this function.
