  • 4 AC current sensors.
  • 3 AC Voltage sensors.
  • 1 Temperature port
  • Compute real power.
  • Fit on Raspberrypi 4 holes mounting pattern.
  • AtMega328 Mcu (Arduino UNO)
  • MCP3208 12 bits ADC
  • Stackable with RPICT8_slave and RPI_T8.
  • Onboard voltage transformer

RPICT4W3T1 is the equivalent board to the RPICT4V3 with ZMPT voltage transformer integrated and the addition of a DS18B20 temperature sensor port.

Compatibility

Version Compatible?
Raspberrypi 1 A No
Raspberrypi 1 B No mounting holes.
Raspberrypi 1 B+ Yes
Raspberrypi 2 B Yes
Raspberrypi 3 B Yes
Raspberrypi 3 B+ Yes
Raspberrypi 4 B Yes
Raspberrypi 5 Yes
  • AC Current sensor:
    • SCT-013-000
    • SCT-019
    • SCT-006
  • AC Voltage sensor:
    • ZMPT101B module is integrated.
  • Temperature:
    • DS18B20

VOLTAGE OUTPUT CT SUCH AS SCT-013-030 and other SCT-013-0XX ARE NOT COMPATIBLE WITH THIS BOARD. Only use the SCT-013-000 which is a current output CT.

Temperature Sensor

DS18B20

The temperature port supports mutiple sensor on the same Onewire line.

The sketch is programmed to search for all connected probe at bootup and output all their values when polled.

Multiple probes should connected as shown below.

Connect multiple DS18B20 sensor together

Software Configuration

For any units ordered before the 1st of February 2022 the firmware version is version 3. Please upgrade to firmware version 4.

Upgrading to sketch version 4

First make sure the lcl-package is installed if not done already.

wget lechacal.com/RPICT/tools/lcl-rpict-package_latest.deb
sudo dpkg -i lcl-rpict-package_latest.deb

Now starts a server instance on the Raspberrypi using.

lcl-server.sh

You can now access the Raspberrypi configuration server if you point your browser to the link below

http://raspberrypi:8000/

You can now edit the configuration.
