Arduino Uno R3 Starter Kit
HC-SR 04-Ultrasonic Range Finder
PIR Motion Sensor Detector Module HC-SR501
- Automatic induction: to enter the sensing range of the output is high, people leave the sensing range is automatically delayed off high, output low.
- Photosensitive control (optional, not factory setting) can be set photosensitive control, day or light intensity without induction
- Two kinds of trigger modes: (jumper selectable), Working voltage range: DC 4.5-20V, Power Consumption: 65mA, TL output: 3.3V, 0V
- Unrepeatable trigger: the sensor output high, the delay time is over, the output automatically from high into low
- b - Repeatable trigger: the sensor output high, the delay period, if there is human in its sensing range Activities, the output will remain high until after the delay will leave high to low
