PIR Sensor & Photocell Manufacturer

About Newopto

      Since 2008, Newopto has designed and manufactured optoelectronic components. Our infrared LEDs, photosensitive sensors, PIR motion sensors, and IR LED modules help customers add sensing and control to smart lighting, security, home appliances, and IoT devices.

Our Story

       Newopto Photoelectric Technology Co., Ltd. was founded in Shenzhen in 2008. In 2017, we moved production to Huizhou, just northeast of Shenzhen, to expand capacity, and established two sister companies there: Huizhou Newopto Sensor Technology Co., Ltd. (“Newopto Sensor”) and Huizhou Newopto Electronic Products Co., Ltd. (“Newopto Electronic”). In 2024, we added Huizhou Gantan Technology Co., Ltd. (“Gantan Technology”) to bring Fresnel lens production in-house.

Four Companies, One Integrated Supply Chain

• Newopto Photoelectric: R&D, manufacturing, and sales of environmentally friendly photosensitive sensors, visible-light sensors, and infrared emitter and receiver diodes.
• Newopto Sensor: R&D, manufacturing, and sales of PIR (pyroelectric infrared) motion sensors and sales of PIR Fresnel lenses.

• Newopto Electronic: R&D, manufacturing, and sales of intelligent control modules, including IR LED boards for CCTV cameras, dash cams, and trail cameras, cabled light sensors for video doorbells, and PIR modules.
  

• Gantan Technology: R&D and manufacturing of PIR Fresnel lenses, supplied through Newopto Sensor or Newopto Photoelectric.
