ACS712 Current Sensor Brick

Overview

Electronic brick of current sensor is based on ACS712 sensor, which can accurately detect AC or DC signals. The maximum AC or DC that can be detected can reach 5A, and the present current signal can be read via analog I / O port.

Features

1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.

2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.

3. Terminals with screws for easy wiring and removing.
