- 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.
- AC Current sensor:
- AC Voltage sensor:
- ZMPT101B module is integrated.
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.
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.
The documentation for serial configuration can be found on this page.
Configuration for 3Phase firmware
The online configurator can be used with the RPICT4W3T1. Use a single board of RPICT4V3 when editing the configuration.
Using the manufacture firmware the data output is:
NodeID Vrms1 Vrms2 Vrms3 Realpower1 Realpower2 Realpower3 Irms1 Irms2 Irms3 Irms4 PF1 PF2 PF3 Temperature
Real Powers are computed using the following rules:
RealPower1 -> CT1 & V1
RealPower2 -> CT2 & V2
RealPower3 -> CT3 & V3
These rules can be modified in the configuration if needed.
Other output type can be streamed out. This should be configured in the unit.
All outputs type available are
- Vrms (V)
- Irms (mA)
- Real Power (W)
- Apparent Power (W)
- Power Factor
- Estimated Power
- Reactive Power
This is the default firmware from manufacture.
This sketch can be loaded directly from the Raspberrypi following this guide and executing the commands below.
