After that, solder short Vcc & GND terminals of the two ICs with each other.Ģ) Solder the two IR transmitter LEDs on the Veroboard. You will need the following parts to build this project S.Noġ) Solder the two LM358 ICs on the veroboard. The operating temperature ranges lie in the ranges of 0˚C – 70˚C at ambient whereas the maximum junction temperature can be up to 150˚C. The maximum current rating for the LM358 IC is 700uA. The supply current for LM358 is 500uA, independent of the supply voltage range. It can be considered as one half of the LM324 Quad op-amp which contains four op-amps with a common power supply. The IC is integrated with two op-amps powered by a common power supply. The heart of this circuit is LM358 IC dual op-amp IC. So, in today’s article, we are going to go over a step by step procedure on how to design a Multi Level Proximity Sensor Using LM358 operational amplifiers These types of IR sensors are generally more preferred over the conventional ones, mainly due to their long operational life. This sensor is used for a wide array of consumer and industrial applications. A multi level proximity sensor allows contact less detection of objects that comes into its line of sight and transduces the obtained information into an electrical signal.
