IC-L7136 LCD Thermometer Circuit

I saw many car product in thermo sensor ,so i would like to show you the LCD thermo sensor which can modify for your car.

When the thermometer is the IC thermo sensor (S8100) or diode (1S1588) is used as thermal sensors.
When using the IC thermo sensor, the thermometry to +100 ° C -40 ° C are possible.
Also, when using the diode, measured at 150 ° C from -20 ° C are possible. Both sensors are contained in the set.
This time I used the diode as a heat sensor to measure more than 100 ° C. ICL 7136 of Intersil (Harris) used for the thermometer and measure the voltage change minute by management before the temperature diodes.
The 3-1/2 digit LCD (SP521PR) applied to the screen. The most significant digit can display a “1″.
ICL7136 electricity consumption is very small and it is possible to run about 3 months with 9-V cell.

The essential parts are contained in the set. The plastic casing and the cell is contained. But there is a cable connecting the sensor.
