You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

As a multi-mode connectivity board, it supports both the LTE Cat M1 and NarrowBand-IoT (LTE Cat.NB) air interfaces and provides fall-back compatibility with the E-GPRS standard. The LPWA LTE ...

While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that can measure pressures as low as 1 Pa. I was not able to find online a ...
