The Micro-system’s typical application is
to be mounted on electronic boards and so that the customer can
easily solder or plug it.
The micro-system is protected from drift due to humidity and is fully calibrated and compensated.
This product can be directly used with a micro-controller without additional
components.
The item is ready and easy to use and is provided with a digital output.
Schematic
The main functions of the microcontroller used:
The timer0 module as a counter.
This is a 8 bit timer, the sensor humidity channel frequency output is connected to its clock (T0CKl pin). The MSB is connected (by software) to the timer1 count Enable (Timer1 gate).
The timer1 module as a counter.
This is a 16 bit timer, the crystal quartz oscillator is connected to his clock (T1CKl pin).
The counting frequency must be at least 1Mhz .
