    This init does not come with the sensor fitted and there is no indication which way it is supposed to fit, if fitted the wrong way the sensor will burn out as I found out by trial and error, It appears you can;t purchased the senor LDR seperately. I think the little buldge goes up when looking at it as in the picture

    This is a very useful little module. Make sure you insert the detector the right way round (bulb side should face the capacitor and pins on the board) otherwise it will burn out! (But if you remove it quickly, after smelling the burning,, with only partial burning it will still work). It is for use with the KY-008 laser modules and can be use for very rapid wireless serial communications between embedded devices like arduino boards, raspberry pi etc. Range is incredible, you can transmit reliable serial data over a 100 metres. Sensor works best at 3.3v I found, laser should be at 5v.
