Product Description

1.Product Overview
HW-HY001 is the latest single board thermal radiation flame alarm sensing module launched by our company. The passive sensor detection adopts a 3-in-1 induction judgment method of infrared+ultraviolet+thermal radiation, and uses the Curie temperature of lithium carbonate crystal material to accurately detect and warn flames with a temperature above 250-4000 ºC and a wavelength of 380-750nm.
The relative dielectric constant is small, and within a wide range of room temperature, there can be significant temperature difference and high contrast polarity changes for fire warning.
The detector has stable performance and can quickly capture and respond within 100ms when a fire occurs, triggering an alarm.
Used for various types of open flame induction fire warning, such as fire warning, security warning, industrial plant, mining area, chemical combustible alarm, household residential, charging station, gas station, charger, equipment and machinery, etc.
2.Operational Principle
HW-HY001 is a flame detector made of lithium carbonate crystal composite material, which uses filters to test the spectra of different bands to detect visible or invisible light radiation while producing smoke and releasing heat during material combustion. Utilize the optical characteristics of flames in the shorter ultraviolet wavelength and longer infrared wavelength to utilize the use of. When different substances burn, their emitted red and ultraviolet spectra differ. By distinguishing the environmental spectrum from the flame spectrum, it triggers a phase change in the sensor's electric field and outputs a warning signal.
3.Product Features
HW-HY001 utilizes a 3-in-1 multivariate sensor to capture signals, with wide coverage, high consistency, low power consumption, and compliance with ROHS, CE, KC, UL and other certification requirements. Moreover, it has strong anti-interference ability and is not affected by environmental temperature, humidity, airflow, dust, noise, brightness, etc. Having special anti-interference ability, it can adapt well to the application scenarios of the vast majority of intelligent product secondary development. This product has better sensing effect when used indoors; When used outdoors, it is normal for the sensing distance to be slightly reduced or the sensitivity to be slightly weak due to the influence of the environment. Users do not need to question the product. This product is mostly used in macro scenarios.
4.Induction Time
The capture time of fire warning will continuously output a trigger signal when the triggering conditions are met, and the LED indicator light will have a constant light indication. When the flame disappears, the flame sensor source will reset within 3-5 seconds to restore detection mode. The induction time is determined by the time of the fire.

7.Thermal radiation spectrogram
1.As shown in the figure: This reference image is obtained by measuring instruments, all of which are based on indoor 100 square meters and indoor temperature of 25 ºC. The flame thermal radiation coefficient is simulated by the testing instrument. This image is for official guidance and reference, and actual applications need to be tested according to the usage environment. The coefficient of thermal radiation transfer of chemical flames can be referred to (Figure 2).
A flame detector uses filters to test the spectra of different wavelengths to detect visible or invisible light radiation that is generated while smoke and heat are released during material combustion. It utilizes the optical characteristics of flames in the shorter ultraviolet and longer infrared wavelengths to make use of them.
When different substances burn, their emitted red and ultraviolet spectra differ, but the three protruding parts of the flame radiation curve can be clearly seen from the flame spectrum diagram. One of them is the part below 0.28μm in the ultraviolet range, and the other two are near 4.3μm and 4.6μm in the infrared range. The solar radiation curve on the surface is located at the trough position in these three bands.
In general, the center wavelength of the filter in the flame detection band is around 4.3μm and 4.4μm, and different bandwidth designs can detect the mid infrared wavelength infrared signals radiated by CO2 and CO gases emitted from hydrocarbon combustion flames in the range of 4.0μm to 4.6μm.
The flame radiation is significantly weaker near 3.8μm and 5.0μm, and is commonly used as a monitoring channel and auxiliary channel for flames, to monitor non fire thermal radiation and solar radiation.
For the 0.185-0.260μm wavelength ultraviolet radiation generated during flame combustion, a solid substance such as silicon carbide or aluminum nitrate can be used as a sensitive element; For the 2.5-3μm wavelength infrared generated in flames, sensors made of aluminum sulfide materials can be used; Sensors made of lead selenide or aluminum tantalate materials can be used for the infrared radiation of 4.4-4.6μm wavelengths generated by flames. Different sensors can be selected based on the spectra emitted by different fuel combustion. The sensing coefficient of the sensor corresponds to a chart, which can be used for various chemical substances such as organic and combustible substances (as shown in Figure 3). This sensor triggers an extreme heat radiation flame spectrum in the range of 380-750 or above, which can achieve alarm perception.

8.Flame thermal radiation filter
From a material perspective, filters provide sensors with the filtering effect of natural chaotic spectra, including optical glass coatings, colored glass, and plastic infrared filters. This refers to near-infrared filters. If it involves mid to far infrared, materials such as Si, ZnSe, Sapphire, CaF2, quartz glass, etc. From the perspective of optical properties, there are two types of filters: long wave pass IR filter and bandpass IR bandpass filter. Among them, the long wave pass type.
(1) Made of colored glass, usually black, such as IPG-800. It absorbs visible light and allows for the transmission of infrared light. If you look at the sun through this infrared filter, you can still see a red sun. Suitable for infrared imaging.
(2) Infrared filters, such as IPGC-720, are made by vacuum coating on optical white glass. This type of filter, also known as optical cold mirrors, reflects visible light and allows infrared light to pass through. The appearance looks silver, like a mirror. If it is a medium to far infrared filter, it needs to be coated on Si, Sapphire, and quartz glass.
(3) The infrared plastic filter made of special plastic has a black appearance. If you look at the sun through this infrared filter, you can also see a red sun. The material of this plastic can be PC or PMMA.
The bandpass filters are all made by vacuum coating. For near-infrared bandpass, it is coated on white glass. If it is mid to far infrared, it will be coated on Sapphire. Everyone can add. The corresponding light sources for the near-infrared bandpass filter are mainly infrared IR LEDs and infrared lasers, so the main wavelengths are 808nm, 850nm, 905nm, 940nm, 1064nm, as well as the less commonly used 780nm. So the wavelengths of commonly used near-infrared filters are mainly these. The corresponding models include BPF-850, NBF-808, and BPF-940.

Product usage scenarios and installation renderings

During product installation testing and actual assembly, please make sure to keep the sensor module stable, and do a precise sealing that is waterproof, moisture-proof, and dust-proof to prevent internal water damage to the sensor. The sensor installation needs to keep the mirror surface clean and tidy, and the outer glass should not have cracks or damage. There should be no obstacles blocking the sensing surface glass. Prevent direct sunlight, high-power visible light, or close proximity to obstacles, etc.
