Thank you patrik, i already ordered an sct-013-005, but i need sometimes higher measurements than 5a. With this second sensor i will be able to compare the results.
yeah 5A is within its range. I usually sit between 1A-20A
Had a chance to sit down and build this node. Made a few tweaks which you may be interested in.
Rewrote the code to sleep for 60 seconds between measurements. This saves approx 80% power ( 22mA down to 4.6mA on my 3.3v pro mini). This also corrects for the drift in the original code which resulted in gaining a second every few mins of measurements (its now only 2ms/min)
Added battery level monitoring which is reported in volts every hour and require no additional hardware or wiring than the originally posted circuit but requires a new vcc library. The actual votlage is only reported if the battery level has changed since the last reading - to save power) .
Let me know what you think:
