is a simple serial communication program, similar to read pressure sensors, online example,
let me give you a direction, a serial port communication, ha ha, only more than 10 years ago, now you think you have a need to use this thing? I have several products are used in temperature and humidity collection of physical quantities, but certainly not a serial port communication, terminal equipment frequency conversion interface - PC - 485 communication protocol, this is the most compatible mode, and several other more concise and effective way, you can practice to explore,
my way is to use NODEMCU for temperature and humidity, and then via WIFI using UDP manner to VB.NET application,
