Typical Throttle Position Sensor Circuit Diagram
Here is a typical schematic diagram of the car Throttle Position Sensor Circuit. The Throttle Position Sensor (TPS) is designed to indicates the position of the throttle valve. Usually the Throttle Position Sensor is mounted on the throttle body and converts the throttle valve angle into an electrical signals. Inside the TPS is a resistor and a wiper arm. The arm is always contacting the resistor.
How the Throttle Position Sensor works?
A wiper arm inside the sensor is mechanically connected to a moving part, such as valve or vane. As the part moves, the wiper arm also moves. The wiper arm is also in contact with a resistor. As the wiper arm moves on the resistor, the signal voltage output changes which indicates position.

Sensor and Detector Liquids Wiring diagram Schematic
This is a very simple liquid detector which controls a relay, this gives you the option to be used for hundreds of applications. You can use it as a float switch to turn on the water pump alarm, rain, etc.. He uses a 4093 IC and transistor can be anyone, provided that it meets the power relay. This sensor can be used with Arduino no problem .

Alcohol Gas Sensor MQ 3
Alcohol Gas Sensor MQ-3 is an alcohol sensor is suitable for detecting levels of alcohol directly, for example on our breath.
Alcohol Sensor MQ-3 has high sensitivity and fast response time. Alcohol Sensor MQ-3 series drivers for alcohol Sensor MQ-3 is very simple, only need 1 piece of variable resistors. Output of Sensor MQ-3 alcohol in the form of an analog voltage that is proportional to the alcohol content is received. The necessary interface is quite simple, can use the ADC that can respond to voltage 0 volt - 3.3 volt saja.Nilai mounted resistors must be differentiated for various types of gas concentration. So need to be calibrated to 0.4 mg / L (about 200ppm) concentrations of alcohol in the air and on the output resistance of about 200K (100K to 470K)| Alcohol Gas Sensor MQ-3 |
Featured Alcohol Gas Sensor MQ-3:
- Sensitivity to high alcohol and low on gasoline
- Fast response and high sensitivity
- Stable and durable
- 5VDC or AC voltage source
- Operating Temperature -10 70 degree C samapai
- Current consumption less than 750mW

Dual Sensor 555 Timer Alarm
This electronic schema is a very nice and simple alarm schema that is based on the 555 timer integrated schema. This alarm schema can be used with many types of sensors like : light or temperature sensors. As you can see below some types of sensors that can be connected at this type of alarm schema ( darkness , light , cold and heat sensor ).
If the sensor detects that the temperature or light is outside of the desired range the alarm will be activated .By turning the potentiometer from the base of Q1 you will modify the sensibility of the sensor . When the alarm is activated the Q2 transistor acts as an audio amplifier and speaker driver for the 16 ohms speaker .
