The HT1621 chip design to replace the direct use of single-chip I / O port LCD display drivers, LCD driver enable more convenient and flexible, easier connection to the purpose of real-time display of temperature. The design principle of the realization of RC charge-discharge measurement of the heating temperature, compared with the cost of thermal resistance is much lower. Six keys to choose the way of the heaters to achieve real-time display of time, heat resistance wire, high temperature, low temperature, the choice of the size of th
