ISB-TS45H Infrared Thermopile Sensor can be widely used in non-contact temperature measurement. This product consists of infrared filters, thermistors and other components, and packaged by TO-46Made of metal, it has high reliability and high sensitivity.

PIR sensor sense the motion object, always used to detet the human. There is a detect rang for the PIR sensor. When a people move in or out of the detect rang, the PIR sensor will be triggered. PIR sensor are low-power, small, easy to used. For this reason it can be used for the alarm system and lighting control. PIR sensor also named passive infrared, Pyroelectric or IR motion sensor.

A photoresistor (or light-dependent resistor, LDR, or photo-conductive cell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits.

Photodiode, or photodiode, is a light sensor that converts light into a current or voltage signal, depending on the usage. The chip inside is a photosensitive PN junction, which is very sensitive to light changes . Therefore, the intensity of light can be used to change the current in the circuit. You can find it in most light sensing and control devices.

Fresnel Lens are widely used in human motion switch, intrusion alarm system, infrared thermal sensor. There are different angle, detect distance, size for you choose.  S9001 is the most popular item in the market. The fresnel lens is a optical element, one side is smooth, another side is by a ring a part of concentric garden composition. Fresnel lens arrays designed for Passive Infrared Sensor. The optical surface increases lens sensitivity for PIR sensor application. All the PIR sensor must work with the Fresnel Lens. Fresnel lens is more competitive than the traditional optical lens.

New Smart PIR Sensor Module with improved digital sensor. This unit has enhanced delay time adjustments, with an expanded range from 2 seconds to 70 minutes. The unit includes an integral light sensor with adjustable sensitivity, the unit is suitable for outdoor and indoor mounting. Detecting length is also adjustable. The output is a standard TTL output signal, that can be used with a microcontroller or for switching lights, etc.

Infrared bandpass fliter can sharply blocklight under special wavelength, effectively transmit required energy. Infrared bandpass fliter is made of optical IR transmission substrate, coating with durable dielectric film. High resistance of general cleaning. Widely used in high quality optical components. Size customized by different requirements.

The Model 161 Series are low range differential pressure transducers and transmitters in HVAC building automation, high accuracy pharmaceutical and health care facilities. The patented variable capacitance pressure sensor is constructed by stainless steel and glass, no glue or other organics. That provides excellent performance, corrosion resistance and long-term stability, the Model 161 delivers reliable measurements below 0.05 inches of water.
