- Asus Tinkerboard has been reported to work with RPICT units. Note we wont be able to provide support for the Tinkerboard.
Current Sensor
Recommended sensor: SCT-013-000
For AC current only.
Temperature Sensor
Connector: 3.5mm Jack
The intended temperature sensor is the DS18B20.
The connector is a 3 way screw terminal connector.
Configuration
Starting from sketch version 1.4 the RPICT4T4 is configured over serial.
See general instructions for configuration over serial.
Emoncms Config (Emonhub)
For default configuration.
[[11]]
nodename = RPICT4T4
hardware = RPICT4T4
[[[rx]]]
names = Power1, Power2, Power3, Power4, T1, T2, T3, T4
datacode = 0
scales = 1,1,1,1,1,1,1,1
units = W,W,W,W,C,C,C,C
Python Example
Please note the uploaded sketch must have CSV enabled. The example script below will be a good starting point.
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[0])
elif i in [1,2,3,4]:
print ("Power %d: %s W" % (i, Z[i]))
else:
print ("Temperature %d: %s C" % (i,Z[i]))
except KeyboardInterrupt:
ser.close()Files
