Description
Acs712 current meter module based on the ACS712ELC-20A chip. With this sensor you can measure both alternating and direct current up to a maximum of 20A. Suitable for measuring 230V mains voltage.
The sensor module can measure 20A positive and negative. The output is 100mV per measured Ampere.
Acs712 specifications:
– Sensor chip: ACS712ELC-20A
– Works on: 5V
!Please note 230V is not a hobby voltage!

Accurately measure current with almost negligible series resistance of a few milliohms, both direct and alternating current. Just like a multimeter, you can reverse the connections for the current to be measured, a minus sign will then appear in front of the measured current if you measure direct current. If you want to measure from a few milliamperes, this sensor is not suitable, but currents between 50 and 20.000 milliamperes are measured accurately with steps of 10 milliamperes (= 0.01 A).
Easy to connect to the analog input of the Arduino. The code is easy to find by googling "acs712 Arduino". For measuring alternating current you have to search longer to find information about that.
I have used this sensor to measure 220 Volt alternating currents and it works very well and accurately, but this is not recommended without expertise for safety reasons.
