Perfect for autonomous fire bots

The five-channel setup provides excellent coverage compared to single sensors. Integration with my Arduino-based firefighting robot was seamless using the digital output.

Good value for multi-sensor array

Buying one module with 5 channels is much cheaper and easier to wire than buying 5 separate modules. The detection range is consistent across all channels.

Reliable performance

Been testing this for two weeks in various lighting conditions. It ignores standard room lights but picks up candle flames reliably. Highly recommended for safety robots.

Excellent for learning projects

Used this for a university final year project. The documentation online is helpful, and the sensor reacts instantly to a lighter flame from about 30cm away.

Great sensitivity, needs calibration

Very responsive to flame sources. You do need to spend time calibrating the potentiometers for each channel to avoid false positives from sunlight, but once set, it works great.

Robust build quality

The PCB feels sturdy and the soldering points are clean. Having both analog and digital outputs gives me flexibility in how I process the data for my competition bot.

5 FAQ

Q: What is the maximum effective detection distance?

A: Under normal indoor lighting conditions, the sensor can typically detect a standard candle flame up to 100cm away. Direct sunlight or strong IR sources may reduce this range.

Q: Is this compatible with Raspberry Pi GPIO pins?

A: Yes, it is compatible. However, since Raspberry Pi GPIOs are 3.3V logic, ensure you power the module at 3.3V or use a logic level converter if powering at 5V to protect the Pi.

Q: Do all five channels output signals simultaneously?

A: Yes, all five channels operate independently and simultaneously. Each channel has its own digital output pin, allowing you to determine the direction of the flame source based on which pins go low.

Q: Does the package include connecting wires?

A: The module comes as a standalone PCB. Connecting wires or header pins are not included in the standard package, but they are commonly available and easy to solder on.

Q: Can this sensor detect gas leaks or only open flames?

A: This module is designed specifically to detect the infrared spectrum emitted by open flames (760nm-1100nm). It is not calibrated for detecting gas leaks; you would need a specific MQ-series gas sensor for that purpose.
