This temperature & humidity sensor provides a pre-calibrated digital output. A unique capacitive sensor element measures relative humidity and the temperature is measured by a negative temperature coefficient (NTC) thermistor. It has...

This new version of button twig contains one independent button, which are configured with pull-down resistor ? Ready for use with our microcontrollers as digital input. The button signals the SIG wire,NC is not used on this twig....

This straight bar load cell (sometimes called a strain gauge) can translate up to 10kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and...

Put the pedal to the metal with this metal foot switch. This is the same kind of foot pedal you might find switching the power supply for a tattoo machine or as a sustain pedal on an electric piano. The non-slip pad on top and rubber...
