Small motion sensor HC-SR505 detects movement in its environment and it is based on infrared technology. It easily connects with Croduino/Arduino via digital pins. When it detects movement, digital output pin sets to HIGH (3.3V, analog 675).

• Model: HC-SR505
• Voltage: 4.5V – 20V DC
• Detection angle: <100 degrees
• Detection range: 3m
• Dimensions: 40 x 10 x 11mm

This module lowers the input voltage to a specific output voltage which you adjust via a trimmer on the board. It is very practical because by changing the input voltage, the output always remains the same. It converts voltages with high efficiency, significantly higher than standard voltage regulators.

• Input Voltage: 4.5V – 28V
• Output Voltage: 0.8V – 20V
• Max. current on the output: 3A
• Efficiency: do 96%
• Dimensions: 22 x 17 x 4 mm
• Current Peak: 4A
• Frequency: 100kHz do 1.5MHz

There is no protection diode in case of wrong polarity, be careful when connecting!
