A resistive strain gauge sensor with a 350 ohm nominal resistance which varies when a force is applied. By measuring the change in the sensors resistance a measurement of the force applied to it can be obtained. Note that strain gauges exhibit small changes in resistance and so this sensor should be used in a Wheatstone bridge...
A small illuminated capacitive toggle switch. This touch sensitive switch will toggle between its on and off state each time its front panel is touched (note that the switch can be modified to operate as a momentary switch - see note below). When in the on state the switch will illuminate via an LED backlight changing the switch from the opaque white to one of 4 colours (red, yellow, green or...
The AM312 is an ultra-miniature PIR module which uses a pyroelectric sensor similar to the one found in the common SR501 but in a more compact form factor.
The SR505 is a miniature PIR module which uses a pyroelectric sensor similar to the one found in the common SR501 but in a more compact form factor. It can be powered from a 5 to 12V supply and when triggered its output pin will go high (3.3V) for approximately 8 seconds before returning back to 0V. This makes it suitable for directly interfacing to both 3.3 and 5V microcontrollers.
