Linear Light Sensor, we also call it phototransistor or photosensitive resistance. The chip integrated inside is very sensitive to light changes. So normally it is used to detect the current ambient light level and converts the light energy into an electrical signal output.

Compared with traditional photoresistors, light sensor is more environment friendly and complied with ROHS requirements. We can also make it to be SMD type with mini size. It is more and more popular now.

Non contact type thermometer 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 non contact temperature measurement sensors. 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.

Overview

PIR core introduction: Polyisocyanurate foam refers to a foamed plastic containing an isocyanurate ring in its molecular structure. In addition, with the excellent thermal insulation properties of polyurethane rigid foam and the advantage of good strength at low density, it is common with ordinary. Compared with polyurethane rigid foam, its most obivious feature is its good flame retardant performance and temperature resistance. Especially its better flame retardant performance, which has attracted wide attention. Therefore, it has been obtained at home and abroad in recent years with its rapid development.

Overview

Senba Sensing Technology Co.,Ltd., was founded in 2005, which is focus on the photoelectric components, such as light dependent photo control sensor. Photosensitive resistance is the resistance of a semiconductor material, the conductivity change with light intensity varies.The use of this feature will work made of different shapes and light-receiving area of the photosensitive resistance.

Feature

Small volume

Fast response

Good spectrum characteristic

Applications

Camera shutter control

LDRs can be used to control the shutter speed on a camera. The LDR would be used to measure the light intensity which then adjusts the camera shutter speed to the appropriate level.

Senba is the specialist PIR manufacturer for more than 15 years. We are the most advanced factory with complete categories. With strong R&D center, there are digital type and analog type, dual elements and four elements for you choose. The market cover domestic market, Korean, Amertica, Turkey and Europe.

Overview

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

Feature

Slight movement can be detectable

High immunity to external noise (vibration, etc.)

Custom design is available.

FAQ

1.What can trigger a low voltage PIR sensor?

Five Causes of PIR False Alarms. The first cause of PIR false alarms is low or unstable voltage at the detector. Test to make sure the voltage at each PIR is above 13VDC and stable. The second cause of false alarms is sudden infrared movement / heat changes in view of the detector.

2.How do PIR sensors work?

When the wide angle pir sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves.

We have photoresistors for sale!

Light dependent resistor sensor 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 area. LDR photoresistor is widely used in many industries, such as toys, lamps, camera, etc.       

The photoconductive resistance 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 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).

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. pir motion sensor with light sensor    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 pir sensor for light control 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.
