Non Contact Thermometer

Non-contact temperature measurement solution

The traditional body temperature measurement is a contact measurement using a mercury thermometer, which has the advantages of stable performance and small error, but has the disadvantages of long measurement time, high risk of cross-contamination, and easy to cause mercury poisoning due to glass breakage.

Infrared ear thermometer is the most commonly used thermometer. It can test body temperature with a slight amount of forehead or ear, and it can also prevent body infection. Infrared ear thermometer collects infrared radiation from ear cavity and tympanic membrane through infrared sensor/ infrared photoresistor. And converted into a digital signal, the main control CPU unit converts the digital signal into a temperature value and displays it on the LCD screen. Compared with mercury thermometers, infrared ear thermometers have the advantages of high precision, high resolution, fast measurement speed, easy operation, safety and comfort.

Now the country is also banned from mercury production. I believe that the application of infrared ear thermometers will become more and more extensive in the future.

Smart Light

Intelligent lighting solutions

The role of lighting in every family is self-evident. Regardless of the family, leaving the lighting, it is like returning to the ancient times hundreds of years ago, which brought a lot of inconvenience to our lives. It is undoubtedly a terrible thing for modern people to leave the life of lighting. Therefore, many scholars have defined the invention of incandescent lamps as one of the symbols of modern civilization. With the invention of incandescent lamps, various lighting devices began to enter thousands of households.

Thus, a lighting system has been formed in each family. Later, due to the use of various lamps, there was a certain change in the light and shade of the light. However, because it adopts the traditional local style, the control method of opening and closing, it restricts the fast-paced lifestyle of modern people, and also limits its application in modern homes.

With the development of science and technology and the improvement of people's living standards, people have put forward new requirements for the family's lighting system. It not only controls the lighting time and brightness of the lighting source, but also cooperates with the home subsystem to match different applications. The lighting scene, but also to consider the management intelligence and operation simplification and flexibility to adapt to future lighting layout and control changes. An excellent intelligent lighting system can enhance the quality of the home environment and ensure the comfort and health of family life. Therefore, the network switch replaces the traditional switch, and the intelligent lighting system replaces the traditional lighting system, which is an inevitable step in the process of home intelligence.

With the rise of the smart home industry, a new, full of humanized home smart lighting system will bring you all this.

FAQ

1.How long do motion sensor lights stay on?

Most people set their motion detection lights so they will stay on for about one to two minutes.

2.Do motion sensors save electricity?

Motion sensing switches do have some “phantom” energy use. According to this study, motion sensor switches use about a watt of energy on standby mode (23 hours a day) and 5 watts on active mode (about an hour a day). This trims a bit off of your overall savings.

LDR Photoresistors

Light dependent resistor is made of semi conductor material, and the conductance changs with light. According to this characteristic, LDR photoresistors can be produced with different figures and illuminated areas. LDR photoresistor, which is also called LDR photocell or photocell sensor, is widely used in many industries, such as toys, lamps, camera, etc.      

The light sensor is a device which converts light energy of various wavelengths from infrared to UV into the electrical energy(or to an electrical signal). This is the reason why they are named as photoelectric devices. They sense the light during this process, and so can be called as 'photo sensors'.

The light sensor is a passive devices that convert this "light energy" whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as "Photoelectric Devices" or "Photo Sensors" because the convert light energy (photons) into electricity (electrons).

Fresnel Lens

Fresnel lens, also known as threaded lens, Fresnel lens is mostly made of polyolefin material, the surface of the lens is smooth, and the other side is filled with concentric circles from small to large. Its texture is designed to utilize the interference of light and to be based on relative sensitivity and acceptance angle requirements. The quality requirement of the lens is very high. A good lens must have a smooth surface, clear texture. Its thickness varies with the application and normally about 0.6 mm. The lens characteristics are wider surface, thinner and farther detection distance.

There are two functions of Fresnel lens: one is the focusing effect; the other is to divide the detection area into several bright and dark areas, so that the moving object entering the detection area can produce the change of heat release on the PIR in the form of temperature change. It is what we called Infrared signal. We can say that fresnel lens help to strengthen the infrared signal and to make PIR work well.

The Fresnel lens is a convex lens that is equivalent to infrared and visible light in many cases, and the effect is better, but the cost is much lower than that of a conventional convex lens. It is often used in applications where accuracy is not critical, such as slide projectors, thin film magnifiers, infrared detectors, etc.

Normally the lens’ shapes are dome and flat. But these years as the smart home is more and more popular, different lens are needed to match with different controllers. Senba can help customers to design and mould the lens they want.

Analog PIR Sensor

It is a passive sensor based on measuring infrared light radiating from objects within its field of view. The detector itself cannot emit infrared. It is commonly used in burglar alarms and smart lighting applications.

Normally PIR works with a fresnel lens. The human body has a constant body temperature, which is different from the ambient temperature. When a human body moves, this difference is detected by PIR through a Fresnel lens, which outputs an signal.
