The RPIZCT4V3T1 is a great all round and self contained unit. It can be configured to read both single phase and 3 phase systems.
Several temperature sensors can be interfaces. It is made to host a user provided Raspberrypi zero.
Future enhancement will feature mezzanine stack for additional sensor capacity.
An enclosure solution is proposed using aluminium extruded case.
- Hosts RaspberryPi Zero
- ATmega328 mcu (Arduino UNO)
- 4 CT sensors
- 3 AC Voltage
- 1 DS18B20 port (temperature)
- Powered from Raspberrypi (microusb)
- Fits in Aluminium Enclosure from Evatron
- Option to stack mezzanine board for additional sensors.
- AC Current sensor: SCT-013-000
- AC Voltage sensor:
- UK: 77DB-06-09
- EU: 77DE-06-09
- US: 77DA-10-09
- Temperature: 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. If a new probe is connected the arduino mcu should be restarted for the new probe to be registered.
Multiple probes should connected as shown below.
The default configuration can be obtained using the command
The online configurator can be used with the RPIZ_CT4V3T1. Use a single board of RPICT4V3 when editing the configuration.
The board has been designed to fit inside an aluminium extruded enclosure. 3D printed end plates are provided. Enclosure kit is available in the shop.
The RPIZ_CT4V3T1 can be programmed using the NanoProg.
IMPORTANT. Make sure the Raspberrypi Zero is removed before connecting the NanoProg.
Once the Arduino firmware flashed the default config must be loaded using the lcl-rpict-config.py tool.
