In this post I would like to share some random notes on flame sensor rods. My hope is you will find this post interesting… In principle we can use a regular infrared diode or phototransistor to sense ...

The sensor allows the pilot light to be automatically re-ignited if the flame is no longer present. The circuit is a surprisingly simple one, with a PNP transistor being turned on by the flame ...

Called Smart Rod Sensor, the device is exactly what it sounds like: a smart sensor that attaches to fishing poles, where it tracks the number of fish the user has caught, shuttling the data off to ...
