Problem Statement
In a laboratory environment, there are many safety and security issues which can arise on a day-to-day basis which can cause harm and damage to sensitive equipment. Many of these problems are caused due to human error and negligence and can have serious infrastructural and financial setbacks. For instance, if the temperature in the lab were to change drastically due to a window being left open, the change in temperature and humidity could have serious effects on delicate temperature sensitive equipment. Modern sensors today are not equipped with reprogrammable thresholds for temperature and humidity to alert lab owners of potential harm to their equipment. Moreover, lab equipment safety is of paramount importance, with many sensors unable to notify owners of who has entered the lab and at what time.
System Specifications
The device should be portable enough such that it can be mounted to the ceiling or top of fume hood – about 180mm x 60mm and less than 2.5kg (imagine two decks of cards side by side at their longest side).
The device should be powered from a wall outlet and have a battery backup with enough energy to last one week in case the power goes out.
The device should have user friendly interface to receive notifications and calibrate the connected sensors and devices (app with touch controls).
The device design should be modular and customizable to customer requirements (each component can be connected through a Bluetooth connection).
