Fire Detector

The automatic fire alarm system is one of the important components of daily life and industrial safety monitoring system. It is an important means to ensure safe operation, reduce casualties and property losses in the event of fire.

gas sensor for Fire Detector

The traditional smoke and temperature fire detectors use the smoke and temperature characteristics of the fire to identify the flame . Because of its simple manufacturing process and low price, it has been well used in hotels, trains, residential buildings and other places, but these detection methods mostly use the detection concentration method, do not detect the characteristics of the flame itself, so the response time is long, the detection range is narrow, the requirements for the surrounding environment are high, the anti-interference ability is poor, and some situations cannot be predicted, such as smokeless flame etc.

Fire detector, also known as a photosensitive fire detector, is a detector used to respond to the light characteristics of a fire, that is, to detect the light intensity of the flame burning and the flickering frequency of the flame. A flame detector detects when a substance burns, which generates smoke and emits heat, and also generates visible or invisible light radiation that is not in the atmosphere.

This kind of point-type infrared flame detector based on the pyroelectric principle can be applied to multi-band flame detection at long and short distances. It has the advantages of fast response speed, long detection distance and large protection area, especially for the flames formed by hydrocarbon combustion. Therefore, it is more suitable for inflammable and explosive industrial and civil places such as chemical industry, highway tunnel, ammunition warehouse, paint factory, petrochemical enterprise, pharmaceutical enterprise, power plant, logistics warehouse and so on.

Can the Two Voltages of Mq-7 Exist All the Time, or Do They Need to Be Powered Alternately? if It is an Alternate Power Supply, What is the Appropriate Power Supply Time?

It requires alternate power supply. Please check the information on the product manual. This sensor is powered by 1.5V and 5V alternately. The low temperature and low voltage (1.5V) state can detect CO, and the high voltage (5V) is the desorption process. The recommended 5V voltage duration is 60s, 1.5V voltage duration is 90s to alternately supply power. Since it is a desorption process at 5V, it is normal for the voltage to drop when CO is 150ppm.

What is the Difference Between Semiconductor Sensors and Electrochemical Sensors?

There is no good linear correspondence between the gas concentration and voltage of the semiconductor sensor, and it is generally only used for fixed-point calibration products; there is a good linear correspondence between the gas concentration and the output current of the electrochemical sensor, and can be made into quantitative detection products.

What Are the Precautions for Manual Soldering of Semiconductor Sensors?

1. Flux: rosin flux with the least chlorine; 2. Constant temperature soldering iron; 3. Temperature: 250℃; 4. Time: no more than 3 seconds.
