Microcontroller Projects: Fridge Temperature and Humidity Indicator

We can measure temperature and humidity inside the fridge using a normal temperature-humidity indicator but relative humidity (RH) could be inaccurate in that case. The moment the fridge door is opened, RH will shoot up due to ingress or egress of moisture in the surroundings. The small sniffer device, described in this article, picks up temperature and humidity from inside the fridge and transmits on an RF ...

Weather Forecasting on ESP32

In any power utility corporation ash dyke management is a huge issue. For fugitive dust control huge sprinklers that spray water all along the dry portion of the dyke are used but maintenance of these sprinklers is a problem as we really don’t have any idea when it’s going to rain or when it will be windy. So the operators in such corporations were demanding for a weather forecasting terminal to overcome th ...

Balance Beam Controller

The purpose of our final project was to create an unstable system that would allow us to investigate classical control design methods by controlling the system using a microcomputer. [gallery columns="2" size="medium" ids="31225,31226"] This was accomplished by creating a teeter-totter that pivoted around a central fulcrum and was controlled by a servo. The beam acted as a track for a ping pong ball to roll ...
