This Gravity Analog 20A Current Sensor is based on the Hall current sensing principle. It can be used for AC or DC current measurement, has a wide voltage range, a small footprint, requires no soldering and has a high level of precision. This component is the newest member of Gravity series. All Gravity components include a standard 3-pin interface to make it simple to use and easy to connect to all Arduino compatible boards. It is ideal for any automation control applications.
relié à un arduino, trouvé une routine sur al gores interweb et utilisé ce morceau de code pour me donner une lecture plus précise. comparé à un clip DC sur un ampèremètre et cela fonctionne très bien pour notre but - détecter lorsque le moteur atteint 6 ampères.

works as advertised
hooked it up to an arduino, found a routine on al gores interweb and used that chunk of code to give me a more accurate reading. compared it to DC clip on ammeter and it works fine for our purpose - sensing when the motor reaches 6 amps.
