This light sensor circuit that is photos sensor is the gap between light and electronics. This circuit is built by op amp and microcontroller PIC16C63 for control the sensor. This circuit is not precision application, but they can be effectively used in position photo sensing applications minus the headaches of amplifier stability. This is the [...]

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.

LCD car thermo circuit

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 [...]
