This page is for board specific information. More information can be found on the generic page for RPICT series.
The RPI LCT8 has been specifically designed for large CT of 400A and more. CT connector are screw terminal types as opposed to jack connectors.
- 8 AC current sensor
- Fit on Raspberrypi 4 holes mounting pattern.
- ATmega328 Mcu.
- Adapted for 400A CT.
|Raspberrypi 1 A||Yes|
|Raspberrypi 1 B+||Yes|
|Raspberrypi 2 B||Yes|
|Raspberrypi 3 B||Yes|
|Raspberrypi 3 B+||Yes|
AC Current sensor
Most current output CT sensor with 5A secondary can be used. In particular
Enquire with us for other CT.
See general instructions for configuration below:
The board can be configured with the online configurator.
The RPI_LCT8 is not readily stackable.
See this page below for an adaptation to stack 2 units.
Python demo script
First of all make sure you have python-serial package installed
$ sudo apt-get install python-serial
Then copy the following into an executable file and run it.
#!/usr/bin/python2 import serial ser = serial.Serial('/dev/ttyAMA0', 38400) try: while 1: # Read one line from the serial buffer line = ser.readline() # Remove the trailing carriage return line feed line = line[:-2] # Create an array of the data Z = line.split(' ') # Print it nicely print ("----------") for i in range(len(Z)): if i==0: print ("NodeID: %s" % Z) else: print ("Power %d: %s W" % (i, Z[i])) except KeyboardInterrupt: ser.close()
