Imaging & Advanced Photon Sensors
Tip: For very low-light environments, choose a sensor with high sensitivity (BH1750, TSL2591) or use NoIR cameras with an IR light source.
Optical sensor chooser (quick guide)
| Need |
Good first choice |
Notes |
| Measure brightness / ambient light |
BH1750 or TSL2561 |
Ideal for auto-brightness, solar tracking & environment monitoring. |
| Detect light/dark transitions |
LDR or basic photoresistor module |
Best for simple automation (lights on/off, alarms). |
| Detect color of objects |
TCS34725 or TCS3200 |
Used for sorting, RGB reading, and precise color analysis. |
| Short-range IR detection |
IR reflective sensor (TCRT5000/LM393) |
Perfect for line-following and object presence detection. |
| Laser or long-range IR |
Laser distance/IR modules |
Narrow beam, more precise than ultrasonic for small targets. |
| Capture images / video |
Raspberry Pi Camera or ESP32-CAM |
Good for AI, CV, surveillance, and IoT imaging. |
| Detect UV radiation |
UV sensor (ML8511, VEML6070) |
Great for weather stations or environmental dashboards. |
These are common starting recommendations; check product pages for voltage, pins, libraries, and environmental limits.
FAQ
Are these optical sensors compatible with Arduino/ESP32/Raspberry Pi?
Yes—most use analog or I²C interfaces, and imaging modules have strong library support for Arduino, ESP32-CAM, and Raspberry Pi OS.
Can light sensors be used outdoors?
Yes, but check lux rating and consider UV-resistant housings for long exposure.
Why use a dedicated lux sensor instead of an LDR?
Lux sensors provide calibrated readings, wide dynamic range, and stability—ideal for accurate monitoring and automation.
Do camera modules work in low light?
NoIR and IR-illuminated modules perform best in low-light or night conditions.
Do you ship nationwide?
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock items.
