Description: The tunable capacitor has the same function as the fixed capacitor in practical applications, but its flexibility is that it can adjust the size of the capacitor, and by changing this data, it can realize the resonance of the circuit with components such as inductors. Ceramic tunable capacitors have good high-frequency characteristics and can work at hundreds of MHz or more. However, ceramic production and processing are more difficult, so the price is higher and the price of the film is lower. After the ceramic adjustable capacitor is generally adjusted to the appropriate capacitance value, it does not need to be adjusted frequently. At this time, it plays the same role as the ordinary capacitor. If the debugging force is improper or the adjustment frequency is too frequent, it may be damaged. Capacitor. The capacitance of the adjustable capacitors is marked with the maximum capacitance and the minimum capacitance. Generally, there are 2/7P, 3/10P, 5/15P and other specifications, and the variation range is more than 3 times. Parameter: Product Name: Adjustable Capacitor Product model: 3/5/10/20/30/40/50/60/70/120 Plastic seal volume: 6mm Capacity range (PF): 3-120 Rated voltage: 100V Maximum voltage: 220V Insulation resistance: 10000MΩ Temperature: -12c

Heart Rate click carries Maxim's MAX30100 integrated pulse oximetry and heart-rate sensor. It's an optical sensor that derives its readings From emitting two wavelengths of light from two LEDs - a red and an infrared one - then measuring the absorbance of pulsing blood through a Photodetector. This particular LED color combination is optimized for reading the data through the tip of one's finger. The signal is Processed by a low-noise analog signal processing unit and communicated to the target MCU through the mikroBUS I2C interface. Developers of End-user applications should note that the readings can be negatively impacted by excess motion and changes in temperature. Also, too much Pressure can constrict capillary blood flow and therefore diminish the reliability of the data. A programmable INT pin is also available. Uses 3.3V power supply. Key features: Optical sensor: IR and red LED combined with photodetector Measures absorbance of pulsing blood I2C interface plus INT pin 3.3V power supply Key Benefits: Motion artefact resillence Ambient light cancellation Ready-to-use examples save development time Supported in all MikroElektronika compilers Applications Developing algorithms for pulse oximetry and heart rate readings through the tip of a finger.
