The Challenge
At QRL I occasionally need to find failures for system that draw DC current
on certain events. If the system is drawing current for no apparent reason (no
event), there seems to be an issue.
To find such failures you can easily measure the DC current drew from the
power supply. But since the DC current can be within 10 mA and 500 Amps (yes,
not kidding), the requirements against the measurement system are crude.
Especially against the current sensor.
As always, the budget is low. Therefore (actually it is a hobby of mine) I
homebrew a system, which can measure and (very important) log the current. In
addition to that, the system is also able to transmit the data wireless to a
receiver connected to a PC.
The Solution
Based on a micro-computer-system called C-Control I from Conrad
Electronics, I hacked quick and dirty a Basic Code. The Basic program
measures the DC current (I) and the DC voltage (Ubat) once per second.
Subsequently it calculates the Work (Ah), the Power (W) and displays all 4
values on a LC-Display. In addition to that it stores the data in a 64k E²PROM
and, by the same token, transmits the data via a serial wireless link on 433 Mhz
at the speed of max. 9k6 to a PC-Terminal.
