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.

  • 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.
