10PCS -SR505 Human Body Sensor Module Mini IR PIR Human Sensor Detector Module for

-SR505 small human body sensing module is based on infrared technologyAutomatic control products, high sensitivity, strong reliability, ultra-small size, ultra-lowvoltage operating mode. Widely used in types of automatic induction electrical equipmentEspecially automatic control products powered by dry batteries.Fully automatic sensing: when a person enters its sensing range, it outputs a high level.When leaving the sensing range, it will automatically delay to turn off the high level and output low level.Ultra small size.Repeatable triggering : that is, after the sensor outputs a high level, during the delayDuring the interval, if there is a human body moving within its sensing range, its output willIt remains high until the person leaves and then delays the change to high level.is low level (the sensing module will automaticallyautomatically postpone a delay period and start the activity in the last zonetime is the starting point of the delay time).Application scope:Human body sensor lamp mouth human body sensor toySecurity products industrial automation controlAutomatic induction electrical equipment, battery-powered automatic control, etc.The appearance and color of different batches of products may be different, which will not affect the use.Colour:greenMaterial:PCBPackage Contents:10 x ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
