Temperature and humidity sensors often use temperature and humidity integrated probes as temperature measuring components to collect temperature and humidity signals. After being processed by circuits such as voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current, and reverse protection, they are converted into current or voltage signals that are linearly related to temperature and humidity for output. They can also be directly output through interfaces such as 485 or 232 through the main control chip.
