This 3/4 inch electric solenoid valve powered by 12-Volt DC with Filters on inlet and outlet ports are great for projects
This FSR will vary its resistance depending on how much pressure is being applied to the sensing area
Quad band Antenna
It allows you to detect not only the volume of the sound but also the identification of characteristic sound source
When a warm body like a human or animal passes by
Photo-Resistor Sensor (LDR or Photo-cell) 640 This 3/4 inch electric solenoidThis is a very small light sensor . It is called light sensor or photocell or LDR (light dependent sensor) or photo resistor. A photocell changes resistance depending on the amount of light it is exposed to. These little sensors make great ambient light triggers (when light in the room turns on, do something). Features Light resistance : ~1k Ohm Dark resistance : ~10k Ohm Max voltage : 150V Max power: 100mW Dimensions 2 x 4 x 5mm 4mm between pins 31mm
