Battery Charger with Temeperature Sensor
Battery with a LM35 temperature sensor on the charger used to monitor the battery temperature is in charge. Battery temperature sensor is needed because the battery temperature will rise at the time in charge. Battery temperature sensor LM35 temperature sensor has high accuracy in monitoring the battery temperature, it is because the temperature sensor LM35 is a temperature sensor that can convert temperature changes into voltage changes linearly.
At the time of the charge a battery will experience changes in temperature, where the battery temperature will begin to rise when the battery began to fill. To avoid over heat the battery, the battery temperature sensor LM35 temperature sensor is required to terminate the battery charging current to avoid overheating.
On the battery charger circuit temperature sensor with temperature sensor 35 lm above the R1 is used for setting the maximum value of the desired temperature. Therefore, when the temperature was in-charge the battery begins to rise and reach temperatures setup then this series will break the current battery charge.
