[0002] Temperature and humidity sensors, as key components of modern smart devices, are widely used in home, agriculture, industry and other fields with their ability to accurately sense changes in ambient temperature and humidity. It can not only monitor and adjust environmental parameters in real time, but also realize intelligent management and control through data feedback, bringing great convenience and efficiency to people's lives and work. In the context of the intelligent and digital era, temperature and humidity sensors are playing an increasingly important role. Temperature and humidity sensors mostly use integrated temperature and humidity probes as temperature measuring elements to collect temperature and humidity signals. After voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection circuit processing, they are converted into current signals or voltage signals that are linearly related to temperature and humidity for output. They can also be directly output through the main control chip through interfaces such as 485 or 232.
