What is a light sensor?
The light sensor is a sensor which detects changes in brightness levels. It uses a photocell, photo-resistor, or photodetector to detect brightness changes. It differs from a standard motion sensor; a motion sensor will only detect something physical which moves in front of it. Whereas the light sensor will trigger if only the shadow of something passes in front of it.
How does a light sensor work?
The light sensor measures the total amount of illumination received by the sensor. Once it's turned on and calibrated, it will alter you if the brightness level changes. It can only be used indoors, as the sun's brightness changes during the day can trigger it.
Does the light detector work for ghost hunting?
It is believed that ghosts often appear as shadow figures or as semi-transparent humanoid shapes, which may be hard to see with your eyes. However, the sensitive light sensor will detect the slightest disturbance in brightness levels.
Which is the best photodiode sensor?
The best ambient light sensor is currently the Shadow Master by Para4ce. It's pinpoint precise when it comes to measuring brightness levels. And it will trigger and alert you once it detects changes.
How to use the phototransistor sensor.
To use the light sensor, set it down, turn it on, and calibrate it. It can only be used indoors. Once calibrated, ensure you don't walk in front of it or cast shadows. You can ask spirits to step in front of the device to trigger it.
