A Four Channel Remote Control Using EnOcean Pi

In my last couple of blog posts, I did a brief overview of the EnOcean Pi sensor kit from Newark and demonstrated how to compile and run the example code using a Raspberry Pi. In this blog post, I will show a real world example – a four-channel remote control built using the EnOcean Pi in conjunction with the EnOcean pushbutton module.

Compiling and Running EnOcean Sensor Kit Example Code

In my previous post, I took a quick look at the EnOcean sensor kit from Newark for Raspberry Pi and tested its basic functionalities using the Fhem home automation software. In this blog post, I will walk you through the process of compiling and running the example code that comes with the EnOcean Link library. While there are instructions on how to do this, some of the information is out-dated and hard to follow. So I will provide my own step-by-step instructions here.

A Quick Overview of the EnOcean Pi and EnOcean Sensor Kit

I recently got the EnOcean Pi and EnOcean sensor kit from Newark. The sensor kit includes a temperature sensor module (STM330), a magnet contact transmitter module (STM320) and a pushbutton transmitter switch module (PTM210). The EnOcean Pi module is a receiver adapter board that connects directly to the popular Raspberry Pi. It is a gateway for handling the all the communications with the wirelessly connected sensors.

Wavetek 907 Repair, YIG Oscillator Teardown

As I mentioned in my previous posting, there was an issue with my Wavetek 907 microwave frequency generator. While everything was fine during my initial testing, the frequency display is now stuck with an out-of-range display and the adjustable frequency range is limited to between around 6.9 Ghz to 7.9 Ghz (instead of all the way up to 11 Ghz). My initial suspicion was that the PTC heater inside the YIGGunn oscillator was malfunctioning. But as it turned out, it was something else.
