Heartbeat sensor provides a simple way to study the function of the heart which can be measured based on the principle of psycho-physiological signal used as a stimulus for the virtual- reality system. The amount of the blood in the finger changes with respect to time.
The TTP226 is a touch pad detector IC which offers 8 touch key. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Capacitive touch allows electronics to sense when your finger is within a few millimetres of a surface to simulate a button “press” just like how the pushbutton works. Capacitive sensing may…
4 Way Capacitive Touch Switch Module uses the touch-sensing IC TTP224 to sense the touch input thus making it easy to add capacitive touch input to your project. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. The module has 4 touch pads. Power the module with 2.4 ~ 5.5V DC and the…
TEC1-12715 40x40mm Thermoelectric Cooler 15A Peltier Module. Thermoelectric coolers also are known as TEC or Peltier Module create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of…
TEC1-12706 Thermoelectric Peltier Cooler – 12V, 60W. Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own DIY project, what you can do with this Peltier module is limitless. Module consist primarily of semiconductor material sandwiched between ceramic plates and…
Rain Water Drop Sensor Module Connected to 5 v power supply power, no water droplets on induction plate, the DO output for the high level, switch lights out, a drop of water drops, the DO output for the low level, switch indicator,brush away the water droplets, return to again, the output high level state.
This High Sensitivity Vibration Sensor module mainly used for security detecting. This module features high sensitivity, fast response and excellent performance, and it is widely used to for security applications such as anti-theft system for vehicle. The module outputs a logic Low voltage. when vibration detected, and the sensitivity can be adjusted by the potentiometer, which would be convenient for…
Capacitive Touch Sensor Module. The Capacitive Touch Sensor Module TTP223B is useful to control devices just by a touch. Compared to a normal push button, this module is small and is operational.
The capacitive touch switch module, working sink current up to 10A, support stepless dimming, red and blue color indicator and other characteristics, can be widely used in lighting control, toys household appliances, kitchen, bathroom mirror and other products. 10A large sink current, multi-mode can be set mini small size, easy to install red and blue color indicator light LED indicator…
This is a 3000W Thyristor SCR Voltage Regulator Temperature Dimmer for Speed / Light (AC 220V). 3000W Thyristor SCR Voltage Regulator is SCR Dimmer which can be used to control 220V Appliances. It can be used as light dimmer, fan speed controller, stove temperature controller. It is easy and simple to use and can control appliances up to 3000W!
The module is designed to switch heavy DC loads from a single digital pin of your microcontroller. Here is a simple breakout board for the IRF520 Mosfet. Easy hookup to your Arduino or another 3-5v microcontroller. Pulse current through a PWM pin, and use this to control a pump, LED, or other DC device at up to 24v, and ~5A.
Dimming can be achieved by Pulse Skip Modulation:- Method 1 — One or more cycles (sine wave signal) are transferred to the load, while following one or several cycles are blocked. Method 2 — Partial transferrence of each sine wave to the load. Method 3 — Generation of modulated full sine signal of different frequency up to few hundred hertz.…
