I am currently an engineering student in Jomo Kenyatta University of Agriculture and Technology. I am interested in how engineering can be used to solve local problems. Gearbox Kenya had an internship programme which offered an opportunity to build with some friends the projects displayed below.
I am a participatant of the Robotics Dojo program. I look foward to imptoving my skills especially in control methods. I am also interested in mechanical design and embedded programming.
Arduino
The proximity sensor senses the proximity of the user and alerts them to pick a mask beofre leaving. The number of remaining masks is updated each time a mask is picked. Incase the number runs low, the user is notified.
Node MCU
The actuation of the servo motor is dependent on the intensity of the light shining on the LDR. It can be applied for automatic doors and windows.
Node MCU Thingspeak
The pulse-sensor is attached to a point on the subjects body where the pulse can be felt (like the wrist or temple). It senses the pulse and trasmits its signal to Thingspeak through the Node MCU where it can be monitored remotely.
Node MCU Blynk
Control of a motor remotely through Blynk phone application where by its direction of rotation can be changed. It can be applied in remote door control.
Node MCU Blynk
Prototype for an air quality detection system especially with the pandemic. It detects the amount of smoke in air in ppm which if above a pre-dtermined level in send the user a notification through the Blynk phone app.
Arduino
The SR04 proximity sensor is used to sense a person's proximity to the door and the serveo motor (standing in for the door) is actuated when the person is at a set distance away from the door.
Node MCU Google Sheets
A temperature and humidity senssor sends real time data through Node MCU to google sheets where it is logged. It can be applied in monitoring and logging of ambient conditions that can be useful for troubleshooting.
Arduino
When someone brings their hand close to the faucet upto a predefined distance, it automatically turns on the submersible pump which lets the water run. When the person withdraws their hand, the submersible pump is turned off.
