VELLEMAN ARDUINO T000090 TinkerKit LDR Sensor Module

Product Features:

• LDR (or Light Dependant Resistor, or photoresistor) is a variable resistor. Light falling on the sensor decreases its resistance.
• The T000090 Tinkerkit is a LDR (or light dependent resistor, or photo resistor) sensor module.
• This module outputs 5V when the sensor receives no light (the circuit is open) and 0V when exposed to bright light (the circuit is closed). 
• When connected to an input on the Arduino using the Tinkerkit shield, you can expect to read values from 0 to 1023.

• A light dependent resistor
• Signal amplifier
• The standard Tinkerkit 3pin connector
• A green LED that signals that the module is correctly powered
• A yellow LED whose brightness changes according to the amount of lightness
