CSLA2CD

I found that in the fablab:

Honeywell CSLA2CD-W/SCREWS, The hole diameter on this sensor is about 0.43 inches so it would fit up to a size 4 or size 2 AWG wire. SOME ASSEMBLY REQUIRED HERE. You will need to connect one leg of this sensor to a DC voltage source between 6 and 13 volts. For that you will need to use a soldering iron and a voltage regulator. See picture in the listing for a schematic showing detailed information on how to hook this sensor up. This current sensor is a linear output Hall effect transducer. For every Amp that it detects, it changes its output by approx. 0.032 mV. Normal mounting is with 0.375 inch long 4-40 screw and square nut (included) . However you could solder three wires to the pins and put heat shrink around each of them and runs this sensor to wherever you want. (Read More)

Electrically isolated from your power source

3 Micro Second Response Time

Use this sensor with a volt meter, data logger, or data acquisition system

Good for monitoring AC or DC current

Large wire capability - up to size 4 AWG

ACS758: How to measure up to ±50A with this magnetic sensor.

Download the ACS758 sensor Datasheet here.

I receive this one also. But in this document

ACS758 : Is a magnetic Hall effect sensor that :

Can measure very high current ±50A.

Is capable of measuring within high voltage up to 700Vrms.

For 240Vrms mains can measure to 8kW (240Vrms x 35Arms).

Cannot measure below 60W (240V x 0.25A) - due to the magnetic noise effect.

Since my solar pannel I want to monitor is 100W, in the best condition... this one will not be usefull.

ha well, maybe not. This one use a RC filter and it seems to work fine.
