1. An asbestos abatement device, comprising:
a housing defining a housing cavity;
first and second inlet ports coupled to the housing, the first inlet port is configured to measure a first pressure of an asbestos containment environment and the second inlet port is configured to measure a second pressure of an external environment;
a negative air machine outlet coupled to the housing; and
a processor coupled to a circuit board positioned inside the housing cavity, wherein the processor is in communication with the first and second inlet ports and the negative air machine outlet, and wherein the processor is configured to:
receive first pressure data from the first inlet port and second pressure data from the second inlet port;
determine a pressure differential between the asbestos containment environment and the external environment based on the received first pressure data and second pressure data;
determine whether the pressure differential is at or less than a threshold value; and
transmit a signal to the negative air machine outlet, wherein the signal is an ON signal that turns the negative air machine outlet on when the pressure differential is at or less than the threshold value.
