A temperature measurement device includes: a temperature sensor designed to measure a temperature, a thermo-generator forming, with the temperature sensor, what is known as a measurement surface, the thermo-generator being configured to convert thermal energy of the measurement surface into electrical energy, and the sensor being designed to measure a temperature of a sample in contact with the measurement surface, and an electronic board designed to receive the electrical energy converted by the thermo-generator and supply the temperature sensor, the device including the electronic board is positioned a non-zero distance away from the measurement surface in a direction perpendicular to the measurement surface.

A monitoring system is provided that may include a sensor configured to detect at least one characteristic related to at least one axle of a first vehicle. The monitoring system may also include a controller having one or more processors in communication with the sensor. The one or more processors may be configured to restrict movement of the first vehicle based at least in part on the at least one characteristic related to the at least one vehicle axle, and vary movement of a second vehicle based at least in part on the at least one characteristic related to the at least one vehicle axle.
