RPICT8
This page is for board specific information. More information can be found on the generic page for RPICT series.
- 8 AC current sensors.
- Compute real power.
- Fit on Raspberrypi 4 holes mounting pattern.
- AtMega328 Mcu (Arduino UNO)
- MCP3208 ADC
- Stackable (up to 5 boards together)
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/python
import serial
ser = serial.Serial('/dev/ttyAMA0', 38400)
try:
while 1:
response = ser.readline()
z = response.split(",")
if len(z)>=7:
print "Power 1: %s Watts" % z[0]
print "Power 2: %s Watts" % z[1]
print "Power 3: %s Watts" % z[2]
print "Power 4: %s Watts" % z[3]
print "Power 5: %s Watts" % z[4]
print "Power 6: %s Watts" % z[5]
print "Power 7: %s Watts" % z[6]
print "Power 8: %s Watts" % z[7][:-2]
except KeyboardInterrupt:
ser.close()
