A degassing unit comprising a base comprising an attachment means for fluid-tightly attaching to a venting opening of the electronic housing and an opening covered by a semipermeable membrane thereby forming a gas passage; a sensor module including a gas property sensor, the sensor module attachable to the base on an inner side of the base, the sensor module extending away from the semipermeable membrane towards a direction substantially perpendicular to the semipermeable membrane. ## Claims ### Claim 1 An alert system for an electronic housing, comprising: a gas property sensor and a processor, wherein the gas property sensor and the processor are communication couplable to each other via a communication channel, wherein the processor is configured to receive gas property data from the gas property sensor, and further configured to, based on the gas property data, determine a property of a battery comprised in the electronic housing, a degassing unit for attaching to the electronic housing and configured to enable passage of gases and to prevent passage of liquids and solids, wherein the gas property sensor is attached to the degassing unit at an inner side which is a side for facing an interior of the electronic housing. ### Claim 2 (depends on 1) The alert system of claim 1, wherein the processor is comprised by a battery management system and wherein the communication channel comprises a first wired communication channel and a second wireless communication channel. ### Claim 3 (depends on 1) The alert system of claim 1, wherein one of the first and second wireless communication channels is a main channel and the other one is a backup channel, and wherein the processor is configured to received data via the main channel and, when the main channel is faulty, receive data via the backup channel. ### Claim 4 (depends on 1) The alert system of claim 1, wherein the processor is configured to determine whether the communication channel is faulty, and issue an alert when determined that said communication channel is faulty. ### Claim 5 (depends on 1) The alert system of claim 1, wherein the property of the battery is a probability of a future thermal runaway within a pre-determined period of time. ### Claim 6 A degassing unit for an electronic housing, the degassing unit comprising: a base comprising an attachment means for fluid-tightly attaching the base to a venting opening of the electronic housing and an opening covered by a semipermeable membrane thereby forming a gas passage, the side of the base facing the venting opening being an inner side and the opposite side being an outer side facing the environment when in attached configuration, wherein the semipermeable membrane enables passage of gases and prevents passage of liquids and solids therethrough, wherein the semipermeable membrane is flat, when there is no gas pressure difference between opposing sides of the membrane, a sensor module comprising a gas property sensor, the sensor module attachable to the base on an inner side of the base, wherein the sensor module is configured to, when attached to the base, extends towards a first direction away from the semipermeable membrane. ### Claim 7 (depends on 6) The degassing unit of claim 6, wherein the base comprises a cavity adapted to cooperably engage with the sensor module. ### Claim 8 (depends on 7)

the inner side. ### Claim 10 (depends on 7) The degassing unit of claim 7, further comprising a connector on a side of the sensor module which is outside the cavity for connection with an electronic housing's inner. ### Claim 11 (depends on 10) The degassing unit of claim 10, wherein the connector comprises a sleeve which fits over the external portion of the sensor module and extends on at least on 2 opposite sides of the sensor module. ### Claim 12 (depends on 7) The degassing unit of claim 7, wherein the cavity extends towards the outer side and connectors are blocked from gases from the battery by the sensor module. ### Claim 13 (depends on 7) The degassing unit of claim 7, wherein the cavity and the sensor module are configured such that the sensor module protrudes towards the inner volume. ### Claim 14 (depends on 7) The degassing unit of claim 7, wherein the sensor module comprises openings for allowing gas exchange for sensing and faces towards a central axis of the degassing unit. ### Claim 15 (depends on 7) The degassing unit of claim 7, wherein the sensor module overlaps the semipermeable membrane and covers less than half, preferably between 1/100th and one tenth, of a gas passage area of the gas passage. ### Claim 16 (depends on 7) The degassing unit of claim 7, wherein the sensor module further comprises a locking mechanism for restricting movement of the sensor module in an insertion direction which is a direction in which the sensor module is insertable into the cavity. ### Claim 17 (depends on 7) The degassing unit of claim 7, wherein the locking mechanism is at least one snap lock element for interlocking with the sensor module. ### Claim 18 (depends on 17) The degassing unit of claim 17, wherein a main frame of the base, a wall defining the cavity, and the snap lock element are a monolithic injection molded part. ### Claim 19 (depends on 7) An electronic housing comprising the battery system, a battery management system, and the degassing unit
