Grove Flame Sensor
Introduction Grove Flame Sensor:
The Grove-Flame Sensor can be used to detect fire sources of other light sources of the wavelength in the range and 760nm - 1100 nm. It is based on the YG1006 sensor which by a high-speed and highly sensitive NPN silicon phototransistor.
Due to its black epoxy, the sensor by sensitive to infrared radiation. In firefighting robot game, the sensor plays a very important role, it can be used as and robot's eyes to find the fire source.

Circuit Operation:
A flame sensor module that consists of a flame sensor (IR receiver), resistor, capacitor, potentiometer, and comparator LM393 in an integrated circuit. It can detect infrared light with a wavelength ranging from 700nm to 1000nm.
Sensor failures can be caused by mechanical damage, environmental factors, electrical interference, or calibration errors. These failures can have various effects on the PLC system, such as false readings, loss of communication, or system shutdown.
This sensor detects flame otherwise wavelength within the range of 760 nm – 1100 nm from the light source. This sensor can be easily damaged to high temperature.
So this sensor can be placed at a certain distance from the flame. The flame detection can be done from a 100cm distance and the detection angle will be 600.

How the Grove Flame Sensor Work:
A flame sensor detects the presence of fire or flames. In extremely hazardous environments, flame sensors work to minimise the risks associated with fire. There are several different types of flame sensor - some will raise an alarm while others may activate a fire suppression system or deactivate a combustible fuel line.
Among the many different types of flame sensor, ultraviolet flame sensors, near IR array flame sensors, infrared flame sensors and IR3 flame detection sensors are the most prominent.
In a hazardous environment, such as a petrochemical processing plant, failing to detect gas leaks, fires or explosions could prove disastrous. However, more needs to be done to help distinguish dangerous gas leaks or flames from annoying false alarms. In this article, Artificial Neural Network Technology Improves Gas & Flame Detection in Hazardous Areas, we take a closer look at the different ways we can reduce false alarms.
Frequently Asked Questions
What is the principle of flame sensor?
The sensors in the flame detector will detect the radiation that is sent by the flame, the photoelectric converts the radiant intensity signal of the flame to a relevant voltage signal and this signal would be processed in a single chip microcomputer and converted into a desired output.
What is the function of a flame sensor?
A flame sensor detects the presence of fire or flames. In extremely hazardous environments, flame sensors work to minimise the risks associated with fire.
What is the resistance of a flame sensor?
With a good flame and a good Cad Cell, the resistance reading should usually be between 300 to 1000 ohms. The oil primary control is usually looking for an electrical resistance below 1600 ohms in order to verify the flame is present.
What is the temperature range of a flame sensor?
Notice: The working temperature of the far infrared flame sensor is -25°~85°, and the storage temperature is 30°~100°.
What is a good flame sensor reading?
When the flame lights, you should read between 0.5 and 10 microamps (μA), depending on the furnace. Readings between 2 and 6 are common.
