Usage Instructions
- The photoresistor module is the most sensitive to environmental light. It is generally used to detect the brightness of the surrounding environment and trigger the microcontroller or relay module, etc.
- When the environmental light brightness does not reach the set threshold, the DO pin outputs a high level. When the external environmental light brightness exceeds the set threshold, the DO pin outputs a low level.
- The DO outputcan be directly connected to the microcontroller. Through the microcontroller, the high and low levels can be detected, thereby detecting the change in environmental light brightness.
- The DO outputcan directly drive the relay module, thus forming a light control switch.
- The analog output AO of the module can be connected to the AD module. Through AD conversion, more accurate values of environmental light intensity can be obtained.
Announcement
- It should be noted that when using this module, avoid direct exposure to strong light to prevent damage to the internal components.
- The power polarity must not be reversed. Otherwise, the chip may be damaged. When the switch signal indicator light is on, the output is a low level. When it is off, the output is a high level, the level of the output signal is close to the power voltage.
Application Scenarios
It can be used to adjust the brightness of equipment, detect day and night, or activate light switch, etc. It is widely applied in automatic lighting systems, photocontrol switches, and various intelligent devices.
