Description:
- PCB size:1.5*1.9cm
- work voltage:5V
- output low level when not receive laser signal
- output high level when receive laser signal
The sensor uses a non-modulated laser receiver, please use indoors where no light, sunlight or other fixtures may interfere, recommended for use in dark environments.
Specification :
- Laser sensor: The laser sensor is the most important component of the module. It receives the laser light and converts it into an electrical signal that can be processed by the module's circuitry.
- Photodiode: The photodiode is a semiconductor device that converts light into electrical current. It is used to detect the laser light and convert it into an electrical signal.
- Amplifier: The amplifier is used to amplify the electrical signal produced by the photodiode. This helps to increase the signal-to-noise ratio and improve the overall performance of the module.
- Filter: The filter is used to block out unwanted noise and other signals that may interfere with the laser light detection. It helps to ensure that the module is only detecting the laser light that is being emitted.
- Output circuitry: The output circuitry is responsible for converting the amplified electrical signal into a usable form, such as a digital signal or an analog voltage.
- Power supply: The power supply is used to provide power to the module's circuitry.
