DO NOT TOUCH THE BOARD WHILE THE EXTERNAL POWER SUPPLY IS ON!
Note: This Click board™ needs to be used by trained personnel only while applying high voltages. Special care should be taken when working with hazardous voltage levels.
HOW DOES IT WORK?
Hall Current 18 Click is based on the MCS1806, an isolated Hall-effect current sensor from MPS. Its primary conductor has low resistance and allows current to flow close to the high-accuracy Hall-effect sensors. The current generates a magnetic field that is sensed at two different points by the integrated Hall-effect transducers. The difference in the magnetic field between those two points is converted into a voltage proportional to the applied current. As a low stable offset, a spinning current technique is used.
The MCS1806 outputs an analog signal, which on this board™ can be read in a digital form. For that purpose, Hall Current 18 Click features the MCP3221, a successive approximation A/D converter with a 12-bit resolution from Microchip. The onboard OUT SEL jumper allows you to choose between the analog and digital output of the sensor. The MCP3221 is selected by default. This Click board™ should be connected in series with the load. Two onboard terminal connectors measure the current, one terminal block for the positive and the other for the negative current input.
Hall Current 18 Click can use an analog output to allow the host MCU to read the data as analog values. In addition, over the MCP3221 and standard 2-Wire I2C interface, it can allow the host MCU to read data in a digital form and 12-bit resolution. Data can be transferred at rates of up to 100kbit/s in the Standard and 400kbit/s in the Fast Mode. Also, maximum sample rates of 22.3kSPS with the MCP3221 are possible in a Continuous-Conversion Mode with a clock rate of 400kHz.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
