Octopus Electronic Bricks, you can use them to build electronics projects just as easy as piling bricks. By using Octopus electronic bricks, you may connect Arduino/Freaduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos…even buttons, just plug and play.

OCTOPUS Flame Sensor is a module based on the infrared receiver (IR probe), simple in design, light, convenient, very sensitive. It can be used to detect the source of fire, make a simple fire-fighting robots, produce fire alarms and so on.

Note that the infrared sensor operating temperature is generally from -25 degree to 85 degree,therefore, in order to avoid damage, in the process of use, maintain suitable distance from the flame probe to the flame, not too near.
