Product Highlights- ✅【𝐖𝐀𝐓𝐄𝐑𝐏𝐑𝐎𝐎𝐅 𝐌𝐀𝐓𝐄𝐑𝐈𝐀𝐋】: ip55 rain cover (fog), dust (worm) and other comprehensive weather-related sealed structures, infrared detector can maintain normal operation in harsh environments. in severe weather (fog, rain, dust, etc.) the range of infrared detector can be reduced to 30%.
- ✅【𝐔𝐍𝐈𝐐𝐔𝐄 𝐃𝐄𝐒𝐈𝐆𝐍】: high-power transmitter, 90% sensitivity margin, high-power infrared transmitter-receiver pair tube, low-power processing technology lightning protection circuit design.high level of anti rfi/emi capability and unique digital filter circuit design.
- ✅【𝐈𝐍𝐒𝐓𝐀𝐋𝐋𝐀𝐓𝐈𝐎𝐍】: the best installation height should be more than 20 cm, installation distance should be not less than 1 m; infrared protection device should be vertically placed, and in the same horizontal line.first, please install the receiver, then the transmitter(when in a straight line, off light of receiver goes out), then fix,connect line and complete installation.
- ✅【𝐒𝐀𝐅𝐄 𝐀𝐍𝐃 𝐑𝐄𝐋𝐈𝐀𝐁𝐋𝐄】: the pair of infrared detectors can reliably generate visible infrared rays up to 20 meters long. the barrier detector frequency of the single beam alarm is 1.92 khz, the power supply is 12 v dc and the wavelength is 940 nm.
- ✅【𝐖𝐈𝐃𝐄 𝐀𝐏𝐏𝐋𝐈𝐂𝐀𝐓𝐈𝐎𝐍】: the infrared detector is suitable for security systems in schools, office buildings, hospitals, parking lots, apartments and other places. the barrier detector widely used in alarm systems, access control systems, etc.
- ✅【𝐀𝐂𝐓𝐈𝐕𝐄 𝐑𝐄𝐆𝐔𝐋𝐀𝐓𝐈𝐎𝐍】: resistant to strong light up to 50,000 lux, built-in automatic adjustment of strong light filter system, to avoid the impact of strong light or car lights.moreover, the detector will automatically enhance sensitivity when encountering heavy fog or bad weather.(agc circuit)

Product Highlights
- The proximity function offers plug and play detection to 100 mm (without front glass) thus eliminating the need for factory calibration of the end equipment or sub-assembly.
- Features - working voltage:2.8-3.8v. als, ir led and proximity detector in an optical module; ambient light sensing (als); approximates human eye response;
- The apds-9930 provides digital ambient light sensing (als), ir led and a complete proximity detection system in a single 8 pin package.
- The proximity detection feature operates well from bright sunlight to dark rooms. the wide dynamic range also allows for operation in short distance detection behind dark glass such as a cell phone.
- Features - programmable interrupt function with upper and lower threshold; up to 16-bit resolution; high sensitivity operates behind darkened glass.
