Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter (for example: temperature, blood pressure, humidity, speed, etc.) into a signal which can be measured electrically. Let’s explain the example of temperature. The mercury in the glass thermometer expands and contracts the liquid to convert the measured temperature which can be read by a viewer on the calibrated glass tube.
A pressure sensor, as the name suggests, is a device that senses and measures pressure (usually of gases or liquids). The pressure sensor in electronic circuits is in the form of an integrated circuit that acts as a transducer, that is, it replicates (in the form of an electrical signal) the signal it receives as a function of imposed pressure.
Phidget Touch Sensor The 1129 is a capacitive touch sensor and can detect a touch through plastic, glass, or paper. We recommend a material thickness of up to 1/2”. The sensor can work as a close proximity sensor, sensing objects at a distance of up to 1/2” from the board in all directions without direct contact.
