Light

Datasheet

This is a reflective sensor combines a GaA1As infrared light emitting diode with a high sensitive Darlington phototransistor in a mini package.

The Light sensor module uses the GL5528 photoresistor to detect the light intensity of the environment. The resistance of the sensor decreases when the light intensity of the environment increases. The chip LM358 is used as a voltage follower to enable you get a accurate data.

The flame sensor can be used to detect fire or other wavelength at 760 nm ~ 1100 nm light. In the fire-fighting robot game, the flame plays an important role in the probe, which can be used as the robot's eyes to find fire source or football. It can make use of fire-fighting robots, soccer robots.

Flame sensor probe angle of 60 degrees, the special sensitivity of the flame spectrum, two M3 mounting holes to stabilize the module will not spin.

The flame sensor's operating temperature is -25 degrees Celsius to 85 degrees Celsius, in the course of the flame it should be noted that the probe distance from the flame should not be too close inorder to avoid damage.

Specifications

• Interface:Analog
• Supply Voltage: +5 V
• Detection range: 20cm (4.8V) ~ 100cm (1V)

This is a very small light sensor. A photocell changes (also called a photodetector, CdS or photoconductive cell) resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something).

• Light resistance : ~1k Ohm
• Dark resistance : ~10k Ohm
• Max voltage : 150V
• Max power: 100mW

Dimensions:
