1、Mainly adopt TEMT6000X01 elements, which is a high‑sensitivity visible light photosensitive (NPN type) transistor. 2、The caught tiny light can be changed and magnified about 100 times, and it can be easily recognized by the microcontroller for AD conversion. 3、Its response characteristics to visible illuminance are similar to the characteristics of the human eye, and it can simulate people's judgment on the intensity of ambient light, so as to facilitate the application of friendly interaction with people. 4、When wiring, input the sensor signal end (S end) to the analog port of the single‑chip microcomputer, sense the change of the analog value, and display the corresponding analog value on the serial monitor. 5、There are two kinds of interfaces, one is the anti‑reverse insertion white terminal with a pitch of 2.54mm. When in use, you can use the module's own wire to connect to the microcontroller; the other is a pin header with a pitch of 2.54mm, uses male to female jumps wire, can be directly connected to the microcontroller. Item Type: Light Sensor Module Material: PCB Working Voltage: DC 5V Interface: Anti-reverse interface/pin header interface Positioning Hole Diameter: Approx. 3mm/0.12in Control Signal: Analog signal Illumination Range: 1-5000Lux Purpose: Suitable for operation, learning and development of college students, engineers, technicians, factories, DIY, electronic enthusiasts, etc. 1 x Light Sensor Module
