Measure of current - hall sensor

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.
