This IR module can also be used to calculate the time taken by the elevator to reach the next floor. If the time period exceeds the limit, this indicates that the lift may have been stopped in the middle due to power failure or other issues. This circuit is also designed to detect smokes and other poisonous gasses along with the basic surveillance
