On Friday, October 24^th 2025, the Batch 6 students of the WASCAL Climate Change and Human Habitat (CC & HH) Programme at the Federal University of Technology, Minna (FUT Minna), Niger State, conducted a practical field activity as part of the Urban Development and Green Infrastructure course. The activity focused on installing temperature, air pressure and humidity sensors across selected locations within the university campus to monitor environmental conditions over several days.

Prior to the field activity, Prof. Elke Mertens, the German guest lecturer for the course, and the twelve WASCAL CC HH students spent an hour calibrating the sensors to ensure accuracy and proper functionality. Six sensors were available, and the students were divided into pairs, with each group responsible for one device. The sensors were programmed to collect data continuously from Friday 24^th October to Wednesday 29^th October 2025.

Three sensors were installed at the premises of WASCAL CC HH, one each at the Campus radio (SearchFM 92.3 MHz) and the university Security Unit premises, and one within the courtyard of the female hostel. Prior authorization was obtained before installation. Permission for the female hostel was granted by the Dean of Students, while approval for SearchFM and the Security unit was obtained from the Chief Security Officer (CSO) of the university. The CSO and his team also agreed to monitor the sensors during the data collection period.

The students were enthusiastic and delighted to take part in this practical exercise, which provided them with valuable hands-on experience in environmental monitoring and field data collection. The activity strengthened their understanding of urban climate dynamics and the importance of green infrastructure studies.

Special appreciation goes to Prof. Elke Mertens, who personally purchased the Temperature/Air Pressure/Relative Humidity measuring device to make the hands-on experience possible for the students.

On Wednesday, October 29^th, the data loggers were removed and the data checked. All loggers worked well and gave reasonable results. Here are the results of the 4 days, 15 hours and 45 minutes temperature, relative humidity, and air pressure measurements at one of the flag poles in front of the WASCAL CC HH centre:
