Good sensitivity
Reliable detection within 5 meters. Had to adjust gain slightly for longer range but overall satisfied.

Works but range varies
Functionality is fine but outdoor sunlight interferes significantly. Best for indoor use.
5 FAQ
Q: Can this transmit IR signals too?
A: This module is primarily a receiver. For transmission, you need a separate IR LED.
Q: What is the effective range indoors?
A: Typically up to 10 meters depending on ambient light and the remote used.
Q: Is it compatible with 3.3V logic?
A: Yes, it operates comfortably between 3.3V and 5V DC.
Q: Do you provide code examples?
A: Yes, check the product wiki for Arduino library links and sample sketches.
Q: Can it withstand outdoor weather?
A: The PCB is not weatherproof. We recommend housing it in a waterproof enclosure for outdoor use.
