Electronic device for monitoring vehicle environments

A vehicle-borne system comprising:

• a gateway device to connect with a Wide Area Network;
• and
• a sensor device disposed in a compartment of the vehicle to be monitored, the sensor device comprising:
• an enclosure that defines an internal volume and a plurality of external surfaces, a first external surface of the plurality of external surfaces defining an opening extending therethrough, the enclosure comprising a thermal member exposed to an ambient environment of the compartment at the opening, the thermal member of a material having a greater thermal conductivity than other portions of the enclosure, the other portions of the enclosure having a greater transmissibility of wireless signals than the thermal member, the plurality of external surfaces and the thermal member disposed such that liquids are prevented from entering the internal volume;
• a first printed circuit board (PCB) assembly disposed in the internal volume, wherein the first PCB assembly comprises one or more computer processors, the one or more computer processors comprising wireless transceiver circuitry to wirelessly couple to the gateway device, the one or more computer processors to receive electric power from a power source disposed in the internal volume;
• and
• a second PCB assembly disposed in the internal volume and connected to the first PCB assembly, wherein the second PCB assembly comprises a temperature sensor thermally contacted with the thermal member, and connected with the wireless transceiver circuitry to wirelessly transmit measurements of a temperature of the ambient environment to the gateway device, wherein the second PCB assembly is disposed in the internal volume closer to the first external surface than to a second external surface of the plurality of external surfaces that is opposite the first external surface, wherein the wireless transceiver circuitry is disposed closer to the second external surface than to the first external surface.
