ADC Pi

ADC Pi data logger

We have  a demo script to our GitHub page for datalogging with the ADC Pi and Raspberry Pi to a text file.  The demo python script saves the ADC values every second and adds a timestamp to each reading. You can view and download the demo script and Python library...

ADC Pi on a BeagleBone Black

You to use the ADC Pi board on a BeagleBone Black board. We have a new folder on our GitHub account for BeagleBone Black files at https://github.com/abelectronicsuk/bbb These instructions are based on the default installation of Angstrom which is supplied with the BeagleBone Black. All...

ADC Pi with ACS712

The ADC Pi can also be used with the ACS712 range of current sensors to read AC or DC current. The code sample from our GitHub page will allow you to read the 30 amp version of the ACS712 sensor and display the current flow which is updated every second. View Python demo code on our...

ADC Pi with HIH-4000

In this tutorial we will use the ADC Pi or ADC Pi Plus with a Honeywell HIH-4000 Series Humidity Sensor to make a digital humidity reader. For this you will need your Raspberry Pi, an ADC Pi or ADC Pi Plus, and a Honeywell HIH-4000 Series Humidity Sensor. We will use the AB Electronics...

ADC Pi with TMP36

In this tutorial we will use the ADC Pi with a Analog Devices TMP36 temperature sensor to make a digital thermometer. For this you will need your Raspberry Pi, an ADC Pi and a TMP36 Voltage Output Temperature Sensor. We will use the AB Electronics python library to talk to the ADC Pi,...

ADC Sample Rate Comparison

The ADC Pi and ADC Differential Pi from AB Electronics UK use the MCP3424 analogue to digital converter from Microchip.  The MCP3424 has programmable bit rates from 12 bits to 18 bits and the number of samples that can be taken each second depends on the bit rate you have chosen. ...

Using 4-20mA sensors with the ADC Pi

We often receive enquires for how to use commercial sensors which have a 4-20mA output with the Raspberry Pi. As many of the commercial sensors operate from a 24 volt supply and need to be isolated from the Raspberry Pi it wouldn’t be possible to measure the output current across a load...

Using the ADC Pi with Arduino

The ADC Pi can also be used with the Arduino range of development boards or any other processor which has an I2C interface. The Arduino library for MCP3424 from ArduSat allows you to easily use the 8 different analogue inputs on the ADC Pi with your Arduino project and stack up to 4 ADC Pi...
