MAX232 – RS232 to TTL Converter 3V, 5V Compatible IC
MAX232 is a communication IC. It is used to convert TTL Signals to RS232 Signal and vice versa.?MAX232?provides RS-232 voltage level outputs (approx. ? 7.5 V) from a single + 5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to + 5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.

Heart Rate Pulse Sensor Module
The working of the Pulse/Heart beat sensor is very simple. The sensor has two sides, on one side the LED is placed along with an ambient light sensor and on the other side we have some circuitry. This circuitry is responsible for the amplification and noise cancellation work. The LED on the front side of the sensor is placed over a vein in our human body. This can either be your Finger tip or you ear tips, but it should be placed directly on top of a vein. Perfect for use in various electronics projects in India, Heart Rate Pulse Sensor Module ensures reliability and performance. Ideal for various electronics projects, Heart Rate Pulse Sensor Module offers quality and performance.
