UVM-30A 3V To 5V Ultraviolet Ray Sensor Detection Module Description: Designed to require high reliability and accuracy measurement uv index (UVI) occasions Suitable for measuring total sunshine ultraviolet radiation intensity The world health organization (who) ultraviolet index classification standard Detection of UV wavelength: 200-370 nm Extremely fast response, the interchangeability Adopt the solid polymer having the patent structure, waterproof and dustproof easy to clean Linear output voltage signal Feature: Working voltage: DC 3-5 v Output voltage: DC 0-1 v Test accuracy: + / - 1uv INDEX  Working current: Typical values 0.06 mA, The maximum 0.1 mA Response wavelength: 200 nm to 370 nm Work stability: - 20 ¿¿¿ -- 85 ¿¿¿ Application: Uv tester, uv index instrument, outdoor uv monitoring equipment, sterilization lamp, flame detection Package included: 1 x Ultraviolet Ray Sensor Detection Module

Feature: Auto PIR motion detection for light on/off Durable and energy-saving High sensitivity, high light and low consumption Suitable for corridor, pathway, stair, garden, yard, etc Specification: Color: Silver LED light: White Connector type: E27 Detection range: ≤ 5m Detection angle: About 120° Power: 7W LED Qty: 5730 SMD 12 LED Rated voltage: 85 - 265 V Product dimension: 134mm x 58mm Operation instruction: 1.Bulb can be installed near stair, better to let bulb head turn to exit/entrance 2.The bulb should be keep far away from heater, air condition, fridge, stove, such places which temperature is high and sensitive (over absolute zero degree object will probably make bulb light up) 3.Do not put any shield, furniture, or big object around the bulb 4.Do not turn it to the window for avoiding hot air /white light perturbance, and body motion to wrongly light up the bulb 5.Do not install bulb near gate or airway Work principle: Smart body sensor PIR bulb, when person gets in sense range, bulb will light up and auto light off after 1 minute when person leaves; also it will not light up in the day, only work in dark environment or at night Trouble removal: 1.When install it, it will auto light up and off, occasionally it can auto light up, the reason may be there's animal moving or bulb turns to hot place, or install angle is not correct 2.If it auto light up every 8s and light off every 30s and it repeats that, now you should check whether there's person or animal moving around it, or can take the bulb to another room for checking. Package Included: 1X E27 PIR Motion Sensor Detection LED Lamp
