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.

LM35 Temperature Sensor Modules for Zelio Smart Relay


Some types of Zelio Smart-Relay is equipped with an analog input 0-10V DC, one of which is Zelio SR3B101BD. With the analog input, then the Zelio can accept analog input voltage of the transducer. Thus, Zelio can be used to control analog output system based on the condition of a sensor.
The picture is a LM35 Temperature Sensor Modules for Zelio PLC or a ready-made. This module has a voltage output 0-10V for the measurement of the temperature range 0 ° C - 100 ° C. This module requires a supply voltage between 12-24V DC. Therefore it is suitable for use with Zelio Smart Relay.
LM35 Temperature Sensor Module can be used for applications such as room temperature controller, temperature controller greenhouses, or for experiments in the laboratory.
Here is a sample program that serves Zelio SR3B101BD temperature display on Zelio display and control the turn on the relay when the temperature is more than equal to 50 ° C.



Pictured above is a simulation result when the temperature of 29 ° C. Output Q4 is OFF.



Pictured above is a simulation result when the temperature of 50 ° C. Output Q4 turned ON.
IB-IE is the analog input to 8-bit ADC that converts the analog input 0-10V into digital 0-255. GAIN component in this program to convert function (mapping) data 0-255 to 0-100 ° C. And as a comparator used to compare the component input numeric constants 50. The program also displays temperature data in the display Zelio.
