Introduction It is simple water level indicator which indicates the level of water. That alerts you, if level of water is overflowed. Circuit Diagram <h ...
This is a very simple Temperature Sensor. It uses LM35DT as a semiconductor Temperature Sensor which operates with a +5 volt DC. Circuit Diagram < ...
Introduction A mass flow sensor responds to the amount of a fluid (usually a gas) flowing through a chamber containing the sensor. It is intended to be insensitive to the density of the fluid. A mass airflow sensor is used to ...
Basic IR Transmitter / Receiver (Tx / Rx) pair Infrared sensors work by sending out a beam of IR light, and then computing the distance / reflectivity to any nearby objects from characteristics of the returned (reflected) signal. A simple IR ...
What is Sensor? A sensor is type of transducer that converts the measurand (a quantity or a parameter) into signal carrying information. "Something which can sense and response accordingly is called as Sensor"</stron ...
This is a simple touch dimmer circuit made of IC TT6061 . TT 6061 is specifically designed for this purpose.By touching this touch dimmer you can increase the light intensity of incandescent lamps in three steps. ...
About Now days we are living in very Noise polluted Environment therefore it is very important to know, what is the maximum level of Noise that would be tolerated. Here is a Sensor that detects the Noise Level in the Environment. Sens ...
In an automated installation, all the information needed to control it must be detected in order to be managed by the control systems. The "detection" function is therefore essential in all industrial processes, and knowledge of the various t ...
Introduction Perhaps the most commonly used of all robotic sensors, the "touch sensor" is nothing more than a simple electrical switch; when the lever is pressed an electrical circuit is completed. Touch sensors were used in making ...
Here is the circuit diagram of a very simple and accurate electronic compass using the 1490 digital compass from Dinsmore. The 1490 digital compass is a solid state Hall Effect device which is sensitive to detect the Earth’s magnetic field. The sensor is internally damped to simulate the performance of an ordinary compass. The circuit shown here is the simplest one that can be built around this sensor. ...
Temperature Sensor Types Big differences exist between different temperature sensor or temperature measurement device types. Using one perspective, they can be simply classified into two groups, contact and non-contact. The two links below ta ...
The circuit is nothing but two LEDs (D1 and D2), whose status are controlled by the temperature of the surroundings. The famous IC LM35 is used as the temperature sensor here. ...
Introduction When you're the CTO of a device networking solution company you spend a lot of time speaking to customers about their respective connectivity challenges and different technology options. Over the past few years, a shift has occurre ...
This is just another 20W audio amplifier circuit , but this time based on the LM1875 audio amplifier IC from National Semiconductors. With a 25V dual power supply LM1875 can deliver 20W of audio power into a 4 ohm speaker. ...
This rain detector will give you a heads-up the instant it starts to rain, hopefully giving you time to close windows and bring in possessions. The battery-powered circuit draws virtually no current when the sensor is dry and the current consumption is ...
According to researchers at the Lemelsen Center at MIT, radio frequency identification (RFID) is the tenth most innovative technology of the past 25years. RFID is a technology that helps store data about people or objects o ...
Introduction Within the photoelectric-sensor arena, the diffuse sensing mode has become much more prevalent with the development and refinement of background suppression—the ability of a sensor to see an object and ignore the reflective surfa ...
