We wanted to demo the current going through a huge motor going through a super high ampere motor driver, 160 ampere to be exact. My task is to design and develop an ampere meter, showing the current!

Introduction SN-ACS712 is a breakout board for the fully integrated Hall Effect based linear current sensor, ACS712. There are several types of current sensors and many different ways to measure current of a circuit, but we prefer using Hall effect sensor because it will not affect the load voltage as shunt resistor did. We did a tutorial showing current measurement using ACS756, a 50 ampere current sensor, check it out here. BTW, both these sensors are able...
Introduction After looking through the GSM modem tutorial, I believe you will wonder what can you do with the GSM modem in our daily life. So , I have come out with the idea of using it with the PIR sensor to detect passive infrared (I mean HUMAN). In this tutorial I will use the GSM modem with PIR sensor and SK28A with PIC18F2550. I use the SK28A since it is small and easy to...
In this tutorial, you will going to learn on how to implement and use the flexible bend (for SN-FLX-01 and SN-FLX-02) by using BBFuino and SK28A. The setup and the source code shared at here will result the voltage display on LCD as you bend the flexible sensor.
Introduction BB-ACS756 is a current sensor with integrated Hall Effect. It can be used to measure current and provide precise solution for AC or DC current sensing in industrial, automotive, commercial and communications system. Normally, it is use to measure current in motor control, load detection and other applications. It is use for over current fault protection. The BB-ACS756 is come with the one set of T-connector and a 3 ways angle pin header. Let's...
