RPICT Buying Guide

We aim to answer here most commonly asked questions at buying time.

Which RPICT board should I get?

The choice of the RPICT will depend on the following factors.

• Number of channels.
• 3 phase or single phase.
• Is temperature needed.
• Is a voltage sensor needed.
• RaspberryPi standard or RaspberryPi zero.

Do I need a voltage sensor

If you are looking to estimate power consumption or detect if a device is on or off then you certainly do not need a voltage sensor. In this case we use what we call 'Estimated Power'. Rms current is measured and multiplied by a fixed estimated voltage (say 240, 200 or 110V) to get an estimated power value. You can alternatively just read the RMS current in Ampere if you prefer. RPICT boards used for this are commonly RPICT3T1 and RPICT8.
