Arduino datasheet

9. Ethernet shield
• The Arduino Ethernet Shield allows an Arduino
board to connect to the internet.
• It is based on the Wiznet W5100 Ethernet chip.
LEDs:
PWR: indicates board & shield are powered
LINK: indicates network link & flashes when the shield transmits or receives data
FULLD: indicates full duplex connection
100M: indicates the presence of a 100 Mb/s network connection (as opposed to 10
Mb/s)
RX: flashes when the shield receives data
TX: flashes when the shield sends data
COLL: flashes when network collisions are detected

10. Passive Infrared Motion sensor
Output: Digital pulse high (3V) when
triggered
Sensitivity range: up to 20 feet (6 meters)
Power supply: 5V-12V input voltage

11. Temperature sensor
• Its model number is DS18B20.
• Measures temperatures from -55°C to +125°C.
• Power supply range is 3.0V to 5.5V

12. Magnetic door sensor(MC-31)
