Work in Progress in Round II:Pelumi Wonuola Oluwasanya

Pelumi is a graduate holding a BSc degree in Electrical & Electronic Engineering from Olabisi Onabanjo University (Ago-Iwoye, Nigeria). Currently, Pelumi is a Corp Member at the ICT Department of the Federal University of Technology in Owerri, Nigeria.


Pelumi is working on a design that will eventually be able to measure temperature, pressure and relative humidity. The focus is in first place on the temperature. PelumiĀ“s idea is to introduce the output voltage signal from the temperature sensor to a programmable IC (integrated circuit), which connects to a display and an alarm to alert when pre-specified values are measured.

Pelumi about his progress:

“The original plan was to make use of a 12 Volts power supply to power the circuit but I realize this will make the circuit very bulky and more expensive. Especially because I want to integrate other variables to be measured: pressure and relative humidity possibly. So I’m making use of the 5 Volts provided on the Arduino [that was included in the Maker Package].

Also I discovered that a 1 MEG Ohm resistor would give better sensitivity than the original 100 KOhms, so I have replaced that too.

I have succeeded in getting the temperature sensor to give out readings on the screen via the Arduino, so currently I’m in the process of calibrating the sensor.”
