Schematic of the ACS712 Current Sensor Circuit (tested circuit diagram of the current sensor module) The internal resistance of this conductive path is 1.2 mΩ typical, providing low power loss. The do ...

Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

With a little help from an Arduino mega, ... a hall effect sensor, and a handful of current regulation ICs. ... The rest of the circuit is straightforward.

For evaluation, a board is available (see photo) with five partially-populated current sensor circuit layouts: 10, 20 and 50V/V ICs are in-position, while space is provided for 100 and 200V/V ICs.
