        <description>Bed Sensor

Motivation

Everyone who has become infected with the topic of smart home considers almost continuously how he/she can still automate manual, recurring tasks further. Provided that the appropriate sensors and actuators are already available. A sensor area that seems somewhat underrepresented is the occupancy sensor, e.g. to trigger or refrain from actions by going to bed.</description>

Motivation

In the age of &#039;music streaming&#039;, terrestrial radio listening seems antiquated. In the absence of WLAN or mobile communications, however, it can be an alternative to stay connected to the world, at least while consuming. FM (UKW) transmission was first trial took place in Germany almost 100 years ago (1925). And actually FM was supposed to be discontinued in 2012, but this only became reality in the cable network.

Motivation

If you want to include the shutters in home automation, you need a corresponding control. If you don&#039;t want to retrofit the roller shutters yourself, you can switch to electronic belt winders. These are fully developed but require an external power supply. There are several manufacturers on the market who also have a wireless remote control in their range.

Motivation

Part of the Solar System is the battery management system (BMS). In my case I used a Chinese company JKBMS that has made a name for itself online. One drawback was the missing link between BMS and inverter. Without this link the inverter can only estimate the battery charge level for instance. The following project closed the gap.</description>

Motivation

The annual electricity bill can be surprising if, for example, you are a single household with over 3500KWh. Switching providers may also help to reduce costs, but of course it is better to reduce consumption. But how do you get consumption without using an ammeter behind every device?</description>

Motivation

[ The final sensor logger]
[ and here the back with microSD card slot]

The idea for the following circuit actually arose from the consideration that in addition to recording the consumption of the domestic heating system (here gas), it would also be very interesting to also record the outside and inside temperature. After all, the colder the weather, the more Ito heat. You may already have a temperature measurement system in use at home in the form of a weather station…</description>

Motivation

Solar energy as part of the renewable energy sources is a good alternative to fossil fuels.
The sun&#039;s energy reaches a daily average intensity of around 165 W/m² on the earth&#039;s surface. This can be used directly with photovoltaic systems. In Germany, the annual radiation output (GHI = Global Horizontal Irradiation) is about 1,056kWh/m² and in my adopted country of Thailand it is around 1,800kWh/m² per year.

Motivation

[ The finished Tonohmeter]
Everyone knows the problem that circuits or wiring do not work due to short circuits or interruptions. The domestic multimeter offers a continuity tester that acoustically reveals a low-resistance connection. It only becomes difficult if the location of the short circuit does not reveal itself immediately. A tonohmmeter can be used for such cases. This means that the measured resistance is mapped to the associated pitch. The smaller the resista…</description>
