Need help in project involving microcontroller
I'm currently working on a project which requires the usage of microcontroller and I need help.
The project's objective is to read current(ampere) from vehicle electrical system and activates relay under certain current(ampere) range. For example, if the system reads current(ampere) below 1A, it will activates the relay. If the system read the current(ampere) above 1A, it will deactivates the relay.
My idea is; The flow of the system will start from current(ampere) reading gauge. The current(ampere) reading from the gauge will received by microcontroller. The microcontroller acts to determine the current(ampere) range to activate and deactivates the relay. This system contains 3 device to operate, reading gauge, microcontroller, relay.
My question is; 1) Is the idea above possible ? 2) If the idea is possible, how microcontroller will read the current(ampere) value from the gauge (input for microcontroller) ? 3) Is there any product which contains all the function of these 3 devices and programmable ? Posted in: #Coffee Room
Micro-controllers don’t have specific ports for measuring currents, but they have ADC through which you can measure analog voltages to a certain range.😁
I'm not very sure about the readily available product. Try in your local automobile market. 😔
I think you are complicating by using a MC. If activating a relay is your only application i suggest you to search for some current sensing relays and try using it.😛
Dear CEans- Correct me if i'm wrong.😘
And as @deal2die said Your idea is really feasible
Yes , it is possible . In fact in one of my project I have already send my current value on serve in ampere . In market there is a current sensor named la25-p this is a hall effect sensor it gives you current as for 25 A output of sensor is 5v which can be used with your microcontroller . For more details you can contact me I will help you in your project my contact no. 8218065178
