Detecting a fire source
One of requirements of building an autonomous firefighter robot is to find a fire's source. Fire-detection sensors are available for Arduino and Raspberry Pi. In this section, we'll explore fire-detection sensors.
Grove - flame sensor
If you have a Grove shield from SeeedStudio, we can use the Grove flame sensor to detect a fire. Technically, this sensor uses the YG1006 sensor with high photosensitivity. This sensor is easy to use on Arduino and Raspberry Pi. If you are interested, you can visit the website to obtain further information: https://www.seeedstudio.com/Grove-Flame-Sensor-p-1450.html. You can see the Grove flame sensor here:

SainSmart flame detection sensor module
If you don't have a Grove shield for a flame sensor, you can use any flame sensor module, for instance, the flame sensor module from SainSmart. This sensor module enables the Arduino and Raspberry Pi to be attached to the board. This sensor module is cheap, and you can find it at https://www.sainsmart...
