landa tianrui LDTR - WG0064 HC - SR505 Mini Body Induction Module for Arduino (GREEN)

Main Features:
- Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delay off high, output low
- Ultra-small size
- Repeatable trigger
- Wide operating voltage range: the default operating voltage is DC 4.5 - 20V
- Micropower: quiescent current no more than 50mA, especially for battery-powered automatic control products
- Output high signal: easy to achieve docking with various circuits
