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. http://www.senbasensor.com/non-contact-thermometer.html

Infrared sensors are the sensors that work on Infrared sensing technology to detect the motion of objects. There exist two types of sensors which detect motion with the help of Infrared, one is Active Infrared sensor (AIR sensor) and another one is Passive Infrared sensor (PIR sensor). What is a PIR Motion Sensor ? Passive Infrared Sensor (PIR sensor) or PIR motion sensor is the kind of sensor that measures the Infrared radiations released from objects and thus identify them as moving or still objects. This type of motion sensor is only the receptor of infrared waves and does not release any infrared beam like that is done in Active Infrared sensors.

The PIR (Passive Infrared) motion sensor is a widely used device designed to detect movement by measuring changes in infrared radiation, typically emitted by humans and animals. With an effective PIR motion sensor range of up to 12 meters, it can cover a substantial area, making it ideal for security systems, automatic lighting, and energy-saving applications.

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. http://www.senbasensor.com/products/linear-light-sensor/
