current to voltage converter
I am designing a data logger device and a part from it is I need to convert an amount of current into its corresponding voltage equivalent. I already have an ADC chip that converts analog to digital voltages, this is applicable for analog sensing devices such as liquid level sensors, temperature sensors and pressure sensors that outputs analog voltage. But there are analog devices that outputs current normally within the range of 0-40mA. Example, a water level sesnor outputs a current amounting to 15mA, it should be converted into it corresponding voltage level that will then be converted to digital voltage to determine its corressponding water level.
So can someone help me on how to design a Current to Voltage converter circuit that would satisfy the explanation above. I know that a simple Op-Amp circuit can solve my problem but can someone explain how to do it.
Are there other circuits that can also function as a current to voltage converter.
Hoping for your massive replies!
