* DC sensors with Raspberry

In order to monitor remotely and online via Internet, the high current DC of solar panels and wind turbine an Raspberry project was implemented. These high current values reachvalues greater than 7 amps.

This project is inspired in the following links: 50A Current Sensor, Analogue Sensors On The Raspberry Pi.

This solution uses an analogue to digital converter (ADC) called MCP3008. It uses the SPI bus protocol which is supported by the Pi’s GPIO header.

The monitored values are:

- IDC Solar Panels in amps.

- IDC Wind Turbine in amps.

List of materials and prices:

• Raspberry Pi with SD Card, $ 34.99
• Wifi USB adapter, $ 7.99
• Raspberry case, $ 6.99
• MCP3008, 10.37
• 50A-Current_sensor (AC/DC), $ 17.90
• 100Amp AC/DC Current Sensor Module Board, $17.99
• Breadboard, $ 5.51

The two current sensors are based on ACS758.

This is the breadboard circuit:

This is the phyton code for this project.
