Fire and flame sensor module for use in own projects, Arduino etc. The sensor has a digital output that sends a signal 1, i.e. high 5V when it detects a flame or a signal 0, i.e. GND. The soldered potentiometer allows you to adjust the sensitivity of the sensor. The sensor only has a digital signal D0. Specification: - Supply voltage: 5V - Comparator used: LM393 - LED indicating power - Sensitivity adjustable by potentiometer - Dimensions: 42x14mm - Detection Angle: 60 degrees - Output: digital switching outputs (0 and 1) - With fixed screw hole for easy installation - Weight: 2.1g https://elecena.pl/product/22604993/flame-sensor-fire-detector-on-lm393-arduino 2023-02-22 https://elecena.pl/product/22604993/flame-sensor-fire-detector-on-lm393-arduino 2025-10-29
