Temperature and humidity sensor for GUDE devices with RJ45 sensor connection for reliable environmental monitoring. The sensor 7205 features a combined temperature and humidity sensor. Both parameters are measured and evaluated simultaneously. The hybrid sensor is quickly and conveniently put into operation and is automatically recognized. No further settings are required. Instead of a permanently connected cable, an RJ45 socket is integrated. This allows the combination sensor to be connected with a shielded RJ45 cable of up to 40 meters in length. Existing cables can often be reused for this purpose. The sensor enables real-time monitoring of ambient temperature and humidity. With a maximum cable length of 40 meters, it can be placed in the optimal location within the infrastructure. Potentially hazardous overheating or humidity in the IT or AV environment can thus be detected early, preventing costly failures. Automatic alerts for exceeding or falling below sensor thresholds allow users to intervene proactively and prevent serious escalations.
