Zimbabwe’s mining and construction industries, long plagued by accidents and fatalities, may be entering a new era of safety developed by university students with the helmet integrates artificial intelligence and IoT (Interest of Things) sensors to provide real‑time protection for workers underground and on construction sites.
The innovation is more than a gadge, but it is a lifeline combining GPS tracking, environmental monitoring, and behavioral detection.
The helmet not only saves lives but also reduces operational risks, offering companies a pathway to safer, more efficient, and more sustainable growth.
Speaking to Zimpapers, Masters student at Chinhoyi University Munyaradzi Zhou said the helmet creates a comprehensive safety net for workers.
“Our AI Smart Helmet integrates GPS, alcohol detection, and environmental sensors to give operators real‑time visibility into worker health and location.
“It proactively warns workers against risks, significantly reducing injuries and fatalities,”he said.
Mr Zhou said multi‑modal alerts ensure dangers are communicated instantly.
“Workers hear audible warnings through a Piezoelectric Buzzer and see flashing red lights when danger is detected.
“Supervisors receive sensor data and automated SOS signals at the command center for rapid response,”he said.
Harare Polytechnic Engineering student Darrel Hunda said GPS tracking transforms rescue operations underground.
“We use high‑sensitivity GPS with IMU (Inertial Measurement Unit) and LoRaWAN triangulation to locate miners even where signals are weak.
“In emergencies, last known coordinates and flashing red lights guide rescue teams directly to trapped workers,”he said.
Another co-operator from Harare Polytechnic Grey Sipani-Hungwe said affordability makes adoption possible for all miners.
“Large companies save costs by reducing insurance premiums and legal payouts through improved safety compliance.
“For small‑scale miners, our subscription model makes advanced safety affordable without heavy upfront investment,”he said.
He added that inspiration rooted in saving lives despite technical challenges.
“We were driven by the urgent need for intelligent PPE (Personal Protective Equipment) in hazardous industries.”
“Even with challenges in sensor integration, our goal remained clear—protecting human life through innovation,”he said.
