1. A sensor unit for a fire suppression system, comprising:
a sensor module comprising:
a first housing including a shoulder and a fitting configured to be coupled to a tank containing a fluid;
a pressure sensor located within the first housing and configured to sense a pressure of the fluid and provide pressure data related to the pressure of the fluid; and
a temperature sensor located within the first housing and configured to sense a temperature and provide temperature data related to the temperature of the fluid;
a display module comprising:
a second housing selectively attached to the first housing such that the display module is selectively removable from the sensor module, the second housing including a connector boss having a threaded exterior; and
a user interface configured to display the pressure data to a user;
a nut rotatably coupled to the first housing and configured to engage the shoulder of the first housing, wherein the nut is threaded onto the threaded exterior of the connector boss and engages the shoulder to secure the attachment between the sensor module and the display module;
an antenna configured to wirelessly transfer data; and
a controller operatively coupled to the pressure sensor and the temperature sensor and configured to transfer the pressure data and the temperature data to a network through the antenna.
