sku: SEN-14544

The low current version of the SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for low to moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!


This low current sensor breakout is capable of sensing very small currents down to around 10mA and large currents up to 5A! However, since the output is analog, your usable readings will be limited by noise and the resolution of the ADC reading the output. Additionally, this breakout has full electrical isolation of measured and sensed circuits and (thanks to an on-board amp) can adjust its sensitivity. Although the analog output is adjustable to 80kHz, the bandwidth on the ACS723 Sensor Breakout width filter has been set to 20kHz to reduce noise when using at high gains. The full 80KHz bandwidth that the sensor is capable of can be recovered by closing the JP1 (Bandwidth Select) jumper on the back of the board.


Note: Although the chip itself is rated for up to 2.4kV (RMS) of isolation, the board has not been designed for such high voltage applications.

easily punctured by dog teeth & not durable
Size: Large Size 3, Color: World Cup
I have a medium size dog 25lbs. The tabs all came off within 4 days & deflated/punctured in the same amount of time this ball is not as sturdy as they say.

Quality product but sold on Amazon cheaper with different seller.
Size: Medium Size 2, Color: White-Blue
The size is the reason for the missing star. Made of good quality but found cheaper from another buyer. My 9month Cane Corso hasn't destroyed it yet and enjoys playing keep away with the other dogs.

absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
Size: Large Size 3, Color: White-Blue
I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

Perfect for keep-away
Size: Large Size 3, Color: Red-Blue
I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.
