Heart Beat Sensor

Heart Beat Sensor in chennai

The Heart Beat Sensor provides a simple way to study the heart's function. This sensor monitors the flow of blood through Finger. As the heart forces blood through the blood vessels in the Finger, the amount of blood in the Finger changes with time. The sensor shines a light lobe (small High Bright LED) through the ear and measures the light that is transmitted to LDR. The signal is amplified, inverted and filtered, in the Circuit .By graphing this signal, the heart rate can be determined, and some details of the pumping action of the heart can be seen on the graph square wave Figure shows that the blood flowing through the Finger rises at the start of the heartbeat. This is caused by the contraction of the ventricles forcing blood into the arteries. Soon after the first peak a second, smaller peak is observed. This is caused by the shutting of the heart valve, at the end of the active phase, which raises the pressure in the arteries and the earlobe.

Pulse Oxymeter Sensor

Pulse Oxymeter Sensor in chennai

Heart Rate Click MAX30100 for Arduino Description: 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.

UV Sensor

UV Sensor in chennai

Description: The ML8511 breakout is an easy to use ultraviolet light sensor The MP8511 UV (ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that's detected This breakout can be very handy in creating devices that warn the.. user of sunburn or detect the UV index as it relates to weather conditions. This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW / cm2). If your microcontroller can do an analog to digital signal conversion then you can detect the level of UV! OKI (OKI) to launch the built-in operational amplifier ultraviolet (UV) sensor IC - ML8511. The use of silicon coated product (SOI) on the insulating -CMOS, the company's first analog voltage output, no filter UV sensor. OKI's UV sensor IC is easy thanks to the high degree of integration of SOI-CMOS technology, suitable for digital and analog circuits. OKI, said the company's future will utilize this expertise to strengthen the connection of the microprocessor digital output circuit, and then with the brightness control sensor sensing type (Ambient Light Sensor) constitute a single chip lineup of merchandise; hope not only to future products done for the day at a glance the amount of UV, and ready to grasp the degree of risk decorative UV measurement equipment, and will promote the application to appliances, portable field equipment. ML8511 UV light can be used with an analog voltage output proportional to the amount. Since the output voltage can therefore be directly connected to the MCU built A / D digital / analog converter, no photoelectric converting circuit. And the use of small, low-profile surface-mount package, suitable for use in portable devices.
