Senba Sensing Technology Co., Ltd.


  • Infrared Thermopile Sensor
    Infrared Thermopile Sensor
    Infrared Thermopile Sensor can measure the temperature without contact by detecting the infrared energy of an object. And the higher the temperature, the more infrared energy is produced.
  • Digital PIR Sensor
    Digital PIR Sensor
    On a digital smart integrated circuit chip, a digital smart integrated circuit converts a signal into a 15-bit ADC Digital signal, when the PIR signal exceeds the selected digital threshold, there will be a timed REL level input Out.
  • Analog PIR Sensor
    Analog PIR Sensor
    PIR, pyroelectric infrared sensor, is normally known as a motion detector. It is a passive sensor based on measuring infrared light radiating from objects within its field of view.
  • LDR Photoresistors
    LDR Photoresistors
    Light dependent resistor is made of semi conductor material, and the conductance changs with light. We have high-quality photoresistors for sale.
  • Analog Optoisolator
    Analog Optoisolator
    Linear optocoupler is an optoelectronic device that controls the change in resistance by a change in input current. It is an analog linear optocoupler made by CdS and LED semiconductor.
  • Linear Light Sensor
    Linear Light Sensor
    Photoresistor or light-dependent resistor (the latter is abbreviated as ldr) or lightconductor (photoconductor), commonly used materials are cadmium sulfide, in addition to selenium, aluminum sulfide, etc.
  • Fresnel Lens
    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.
  • PIR Sensor Module
    PIR Sensor Module
    Pyroelectric sensor is a kind of sensor, also known as human body infrared sensor, used for life burglar alarm, visitor notification, etc., the principle is to release the charge through the amplifier into a voltage output.
  • Infrared Bandpass Fliter
    Infrared Bandpass Fliter
    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. Widely used in high quality optical components.
  • Low Differential Pressure Transmitter/Transducer
    Low Differential Pressure Transmitter/Transducer
    For measuring very small pressure differences between two measurement points either side of a ventilation fan, both sides of an air filter or either side of clean room wall.

Owning very strong R&D Center, Senba can research and develop the pyroelectric infrared sensor independently. Among those pir sensor manufacturers, Senba Sensor has become the first owner of this special technology enterprise in China. We are awarded as "Henan high-tech enterprises" in 2006 and awarded as "Notional high-tech enterprises" in 2012.
