Features : 16-key board TTP229 capacitive touch sensor IC,Onboard power indicator,Working voltage: 2.4V-5.5V,The module can be set to output mode, the key output mode, the longest time and fast output / low power options Etc.
The TTP229 is a capacitive touch sensor that can be used as an alternative to push button switches or the matrix keypad in embedded projects. more...
Specification : Base on LM393 and Thermal sensor designed,Power supply 3.3V or 5V,Output signal adjustable sensitivity,Set aside one voltage comparator circuit(P3) Etc.
The Thermal Sensor Module is used a thermal senor and a LM393 dual differential comparator. You can use the potentiometer adjust the sensitivity. Once close to the heat source, the D1 state LED will light, and output signal is 1.1V~1.9V.more...
This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.58�-diameter (1.5 cm) active area, allowing you to create a sensor that is able to detect forcemore...
