This is the circuit diagram of seismic / vibration sensor. The circuit simulates a seismic sensor to detect vibrations/sounds. It’s really sensitive and may detect vibrations due to the motion of animals or human beings. So it could be utilized to monitor protected locations to restrict entry of undesirable individuals or animals. The circuit applies… Read More »
This is a very easy build, simple metal detector circuit, built based on a CS209A IC. The circuit will give surprising results and draws extremely small current from a 9 volt battery. It worked great on the bench, but not so good outside for common metal detecting. But definately a great circuit for sensing studs… Read More »
A well-known IC LM35 is chosen to be the temperature sensor in this circuit. Output voltage of LM35 will increase by 10mV per degree rise in temperature. Output of LM35 is joined to the non inverting input of the operational amplifier (op-amp) of CA3130. The inverting input of the same op-amp could be provided using the required reference voltage using variable resistor R2.
The following circuit is a simple fire alarm circuit based NE555 timer and use thermistor as a temperature detector. This sensor will activate the transistor when the temperature is in high value. The thermistor will have a low resistance at high temperature, while at low temperature, the transistor resistance is high. This characteristic of thermitor… Read More »
This is the color sensor circuit diagram. Color sensor is definitely an exciting project for hobbyists. The circuit can sense eight colors, i.e. blue, green and red (primary colors); magenta, yellow and cyan (secondary colors); and black and white. The circuit is based on the fundamentals of optics and digital electronics. The object whose color… Read More »
Above circuit design is thermocouple amplifier circuit using CA3193 operating amplifier. The CA3193 is an excellent choice for use with thermocouples.? In the circuit, the CA3193 amplifies the generated signal 500 times. The three 22M? resistors will provide full-scale output if the thermocouple opens.
