The industrial automation system and building automation system, often have on the equipment and limit switches that provide the on or off of circuits under the force of pressure exerted on the lever krańcówki. We offer limit switches and force sensors, pressure in the form of Grove compatible modules with the plates of Arduino and Raspberry Pi. A simple way to connect and compact dimensions facilitate the use of Grove sensors in various projects of automation systems and measurements.
Module from the Grove series, is equipped with a sensor of pressure force FSR402. The sensor communicates with the analog voltage signal. It is able to detect a pressure in the range from 0.2 N to 20 N. It is supplied with the voltage from 3.3 V to 5V. It has an analog output that makes it compatible with most of the commissioning modules, including...
FSR sensors used in its construction surface element whose resistance value changes depending on the pressure force on the specified on this element. The surface of the FSR sensor consists of two layers separated from each other by air - conducting layer and dielectric layer. Transmits pressure to the sensor, causing deformation of its conductive layer and the reduction of its resistance. After removal of the load from the sensor, there is an increase in resistance of the conductive layer to the value before application of load to the sensor. Resistive force sensors pressure find application, in particular to electrical musical instruments such as drums and electric keyboards, in which the strength of the kick drum, plate or key, sets the volume of the audio signal at the output of the instrument. They are used as control elements inside the car, for example, to install the outer rear view mirrors.
