Versatile Current Monitor
Approx construction cost US$24
Monitors Equipment current flow and warns if changes significantly.
This neat little monitor module will allow the current flowing through some existing circuit or piece of equipment to be monitored. An audible or visible warning will then be given if it rises above or, alternatively, falls below some preset threshold value. Such a circuit will find numerous uses for power supplies, charging units and certain battery-operated devices.
