Reliable and sensitive

Bought this to teach my kids about safety sensors. It detects a lighter flame from quite a distance. The build quality feels solid for the price point.

Easy integration

The digital output makes coding very straightforward. No complex libraries needed, just a simple digitalRead function. Works perfectly with my ESP32 home automation setup.

Excellent sensitivity adjustment

The blue potentiometer allows for fine-tuning which is crucial for indoor vs outdoor use. Very happy with this purchase for my smart home monitoring system.

Perfect for my robotics project

This sensor works exactly as described. I integrated it into a small fire-fighting robot prototype, and the response time to a candle flame is impressive. The sensitivity potentiometer makes it easy to calibrate for different lighting conditions.

Good value for learning

Great module for university projects. It connects easily to Arduino. Just note that direct sunlight can trigger false positives if not shielded properly, but that is expected with IR sensors.

Does the job well

Solid performance. The detection range is accurate according to the specs. I deducted one star because the included wires are a bit short, but that's a minor issue.

5 FAQ

Q: Can this sensor detect a candle flame through glass?

A: Generally, standard glass blocks most infrared radiation, so detection through a closed window may be unreliable or impossible depending on the glass type. Direct line of sight is recommended for best results.

Q: Does this come with a library for Python?

A: Since this is a digital switch output sensor, it does not require a specific library. You simply read the HIGH/LOW state using standard GPIO commands in Python (RPi.GPIO) or C++ (Arduino IDE).

Q: Is this module compatible with 5V Arduino boards?

A: Yes, the KF2510 module operates comfortably within the 3.3V to 5V range, making it fully compatible with standard 5V Arduino boards like the Uno and Mega.

Q: What is the maximum current consumption of this sensor?

A: The module typically consumes around 20mA when active. Please refer to the datasheet for specific power management recommendations in battery-operated projects.

Q: Can I use this outdoors in the rain?

A: No, this module is not waterproof. It should be housed in a weatherproof enclosure if used outdoors to protect the electronic components from moisture and dust.
