Smoke and gas sensor

The smoke sensor has a built-in potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas. Gas and Smoke Sensors. Each of these sensors is sensitive to specific types of gas.

The internal sensing element is heated up by the current flow, causing nearby gases to ionize and be absorbed by the sensor. It could be used in gas leakage detecting equipments in family and industry. It outputs a voltage between and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The resistance of the sensor is different depending on the type of the gas.

It is suitable for detecting H LPG, CH CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.

Simultaneous measurements were obtained for average gas concentrations, smoke mass concentrations, and smoke optical densities in order to quantify the levels of combustion products at the alert and alarm times of the sensors. The Smoke Sensor is an ultralight, perfectly designed battery device that uses both photoelectric and temperature sensors for maximum protection from flaming and smoldering fires. Wireless smoke detector is a perfect choice for your smart home.

Try out our new smoke detector. You only need one pin to accept the output from the sensor so it will fit nicely into many electronics projects. If you do not have a Natural gas leak detector at your home, it is the high time to get one. It can detect LPG, i-butane, propane, methane ,alcohol, hydrogen and smoke. Some modules have a built-in variable resistor to adjust the sensitivity of the sensor.

A smoke detector is a device that senses smoke , typically as an indicator of fire. Commercial security devices issue a signal to a fire alarm control panel as part of a fire alarm system, while household smoke detectors , also known as smoke alarms, generally issue a local audible or visual alarm from the detector itself or from a number of detectors if there are multiple smoke detectors. It is designed for indoor use at room temperature. Experiments were conducted to evaluate the response characteristics of commercially available gas , smoke , and flame sensors to fires of common combustible mine materials.

The experiments were conducted in the large-scale Fire gallery located at the National. First of all, we need to connect some jumper wires between Arduino and MQsmoke sensor shield. This gas sensor has four pins in total. MQgas sensor is also sensible to LPG, Alcohol, and Methane etc.

This Smoke Detector can be easily built on Bread Board or Dot Board but we have decided to build this as an Arduino Shield on PCB. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas.
