UNN Engr Students Design CO Monitoring System [Video]
Design and Construction of a Carbon Monoxide (CO) Monitoring System Fitted With a Remote Automatic On/Off Switch Control for Mini-Generators
Measurement and Instrumentation Project Designed by 3rd Year Mechanical Engineering Students of the University of Nigeria, Nsukka (UNN)
Carbon Monoxide (CO) gas is a highly poisonous gas that is emitted from the incomplete combustion of fossil fuel. The gas is usually emitted from the exhaust of fossil fuelled power-plants like the mini-generators found in most Nigerian households.
So many people have died while asleep because they inhaled this poisonous gas beyond the medically-prescribed safe limit required for human beings. In order to stop the death of human beings due to the use of mini-generators, it therefore becomes very necessary to build a Carbon Monoxide (CO) Monitoring System that will check the CO level in a room and possess the ability to remotely turn off the generator once the safe limit of the CO in the room close to the generator is exceeded.
The Arduino based measurement system offers a cost-effective and do it yourself method of building measurement systems. This project seeks to design and develop an Arduino based instrument that will monitor (every 30 seconds) the CO level in the room close to the generator and will also have the ability to remotely turn off the generator once the safe limit of CO in the room close to the generator is exceeded.
Components Used For Design:
- Arduino UNO board
- MQ-7 CO Sensor
- NPN Transistor
- 12V 5-pin Relay
- Flywheel diode
- 1KOhm and 10KOhm resistors
- Bread board
- Jumper wires
- 9V battery
The particular Arduino board that was used for the project is called the Arduino UNO. Other types of Arduino such as the MEGA, Due, Ethernet, Nano, etc. exist which have special and different functions than the UNO board.

NLNG Erects Engineering Laboratory For UNN
The Nigeria Liquefied Natural Gas limited (NLNG), is currently constructing an engineering laboratory at the University of Nigeria, Nsukka (UNN).
Speaking during an inspection tour of the project, the Deputy Managing Director of NLNG, Mr Isa Inuwa said the project would costs about 320 million Naira.
He said the Laboratory is part of the company’s contribution to complement the various efforts of government in improving standards.
Mr Inuwa also explained that the laboratory which would be equipped with the state of the art facility is to boost engineering education capacity in the country.
