V2PWM - Voltage Converter Module-to-PWM-Based ATmega8

 
V2PWM module is a converter Voltage-to-PWM functioning in changing the voltage to the PWM pulse. This module has input voltage of 0-5V DC or 0-10V DC, with the output of the PWM pulse. The module is equipped with a L293D motor driver components.

With this module you can control the rotation speed of a DC motor in accordance with the magnitude of the input voltage applied to the module. In addition to pictures, mini fan rotation speed is controlled based on temperature conditions that are read by LM35-Zelio module.

LM35-Zelio module has output voltage between 0-10V DC which represents the value of the temperature between 000-100 degrees Celsius. The output voltage is used as the input voltage of the module V2PWM. This input voltage is converted into a PWM pulse by the microcontroller ATmega8.

Furthermore, the PWM pulse will trigger the DC motor driver L293D, and mini fan will spin at speeds comparable to the magnitude reply temperature measured by LM35-Zelio module. The higher the temperature, then the mini fan will spin faster.

     This module is suitable for experimental material control system uses PLC functions involving analog input and analog output.

To perform experiments analog inputs and analog outputs, normally used as the unit of analogue input module temperature sensor or a temperature controller with an output voltage 0-10V DC. And analog outputs are used as the unit that controls the inverter AC motor rotation speed.

If you need a module to experiment with the functions of PLC analog input and analog output, the LM35-Zelio module and module-to-PWM Voltage you can use. Both are solutions at an economical cost.
