This detection module that allows you to detect your heart rate and blood oxygen level from your Arduino project. You can monitor your blood oxygen level yourself to avoid going to the doctor or pharmacy on purpose. Simply press the sensor with your finger and wait for the reading of hemoglobin (Spo2), heart rate and Perfusion Index (PI%). It is a solution as an integrated heart rate sensor and pulse oximetry, which includes two LEDs, a photodetector and is optimized for analog low noise optics.

This module adapted for the arduino includes a laser diode and a 3-pin connector for a simple and quick adaptation with the Arduino. The diode is mainly used for laser toys, all kinds of level meter, instruments, stylus pen, mini LCD projector, remote listeners laser, alarm anti-theft light remote control. Light shots and different display can make the color of the image element a little different from the real object. The measurement allowed error is +/- 1-3 cm. Characteristic: - Supply voltage: 5VDC
- Connector of 3 pins:
1- GND
2- VCC
3- Light control of the laser diode
- Point mode: point facula
- Continuous output
- Operating temperature: -36 ° C - + 65 ° C
- Laser wavelength: 650nm (red)

You can easily control any device over the Internet through your phone, computer, etc.
The module can handle 5 users at the same time, it can work in two modes: STA (client) and AP (access point).
In AP mode, the module is connected via WIFI directly to your phone or computer (in open field can be up to 300 meters).
In STA mode, the relay module is connected to the access point (router) that supplies the network.
Wi-Fi in the room where the relays are located. In this case, the range mainly depends on the power of the access point antennas (routers).
You should not turn off after the configuration is completed, as some of the parameters of the WIFI module cannot be saved when power is cut off.
