Specification:
Photo resistance sensor light detector module:
Pin strip: 4 pin.
Operating voltage: 3.3V-5V
PCB size: 2.7 cm x 1.4 cm.
Size (L x W): approx. 3.2 cm x 1.4 cm
Output: DO digital switching output (0 and 1), AO analogue voltage output
4 Wire Interfaces:
VCC: positive power supply 3.3-5V.
GND: power supply is negative.
- DO: TTL switching signal output
- AO: Analog output
Use:
1. If it is not a light or light intensity, the value cannot be reached, do intensity output is high level. When light is above the value, do module performance is low level.
2. The digital output module DO can be connected directly to the microcontroller, the use of microcontrollers capture high or low level, so that the environmental light intensity change can be detected.
3. Can use this board digital output interface module drive relay directly DO can also be used as an optical switch.
4. The AO analogue output connects to the AD module, and it can obtain a more accurate light intensity value through the AD converter.
