- 4x AC Current Sensors
- 4x DS18B20 Temperature Sensors
- Attiny84 Mcu
Current Sensor
Recommended sensor: SCT-013-000 50mA/100A
Burden Resistor: 24 Ohm
Connector: 3.5mm Jack
Default Voltage for power calculation: 240V (can be modified in firmware).
For AC current only.
Temperature Sensor
Connector: 3.5mm Jack
The intended temperature sensor is the DS18B20 which can be configure in either parasite or normal mode.
The connection to a 3.5mm jack connector is shown below.
NOTE: Raspberrypi must be switched off while connecting and disconnecting the temperature sensor.
