Good value
Sensitivity takes some tweaking to get right for indoor lighting, but once set it is stable. Good price for the quality.

Okay but basic
Does the job but no analog output available on this specific version. Make sure you need digital only before buying.
Q: Is a library required for Arduino?
A: No library is needed. You can use the standard digitalRead function to read the sensor state.
Q: Is there an analog output pin available?
A: No, this specific module provides a digital TTL output only. Please check our analog sensor series if you need variable voltage output.
Q: Does this work with 3.3V logic systems like ESP32?
A: Yes, the operating voltage range is 3.3V to 5V, so it is fully compatible with ESP32 and similar boards.
Q: What is the typical current consumption?
A: The module typically consumes around 15mA when active. It is suitable for battery-powered projects.
Q: Can it detect direct sunlight without damage?
A: Yes, the photoresistor is designed to handle ambient light variations including sunlight. Adjust the potentiometer for best results.
