RPICT3T1
This page is for board specific information. More information can be found on the generic page for RPICT series.
Overview
The RPICT3T1 measures AC Power and Temperature.
- 3x AC current sensor
- 1x DS18B20 Temperature Sensor
- Attiny84 Microcontroller
Notice
Power is computed using a fixed estimated Voltage. This estimated voltage can be configured. Default value is 240V. You will be able to change this to 110 or 220 depending on the country where it is used.
If you require more accurate power measurement then use the RPICT3V1 board instead. This will also read Voltage and calculate Real Power. A voltage sensor will be required in this case.
Compatibility
Version | Compatible? |
---|---|
Raspberrypi 1 A | Yes |
Raspberrypi 1 B+ | Yes |
Raspberrypi 2 B | Yes |
Raspberrypi 3 B | Yes |
Raspberrypi 3 B+ | Yes |
Configuration
Starting from sketch version 1.1 the RPICT3T1 is configured over serial.
See general instructions for configuration over serial.
Temperature Sensor
The DS18B20 temperature sensor can be connected directly to the screw terminal connector.
Connection is as follow:
Vcc - Red
Din - Yellow
Gnd - Black
Calibration
If calibration is required only ICAL has any effect on the calibration.
VCAL and PHASECAL might be present in the config but have no effect. These should be ignored.
Emoncms Config (Emonhub)
For default configuration. Used as single board only (not stacked).
