====== Other hardware components ======
Here’s a description of hardware components that work well for building automation projects, are cheap but reliable, and can be purchased from Amazon, for example, with a few clicks. These devices use __Modbus__ communication, which integrates well with both Simatic and Arduino systems, as well as Labview applications running on a PC or laptop.


===== Modbus diplays =====

For example, you can get a cheap Modbus display on Amazon, this type: [[https://www.amazon.de/Eujgoov-Anzeige-Peripheriemodule-stellig-MODBUS-RTU/dp/B08PK4Y7JZ/ref=sr_1_1?crid=2RHJRYIR41X6A&keywords=Eujgoov+SPS+Anzeige&qid=1651086562&sprefix=eujgoov+sps+anzeige%2Caps%2C72&sr=8-1|Eujgoov SPS Anzeige]]. The common feature of these is the extremely affordable price and the lousy documentation - and (perhaps surprisingly) they work!

===== Energy meters =====

The meter which is used for measuring the energy utilises by the electric load is known as the energy meter. The energy is the total power consumed and utilised by the load at a particular interval of time. It is used in domestic and industrial AC circuit for measuring the power consumption. The meter is less expensive and accurate.
